A group of drugs used to treat high blood pressure (HYPERTENSION). Untreated hypertension leads to STROKE, heart attacks and heart failure. The high incidence of hypertension in western countries has led to intensive research to discover antihypertensive drugs, and many have been marketed. The drugs may work by reducing the power of the heartbeat, by dilating the blood vessels or by increasing the excretion of salts and water in the urine (diuresis). Antihypertensive treatment has greatly improved the prognosis of patients with high blood pressure by cutting the frequency of heart and renal failure (see KIDNEYS, DISEASES OF), stroke, and coronary thrombosis (see HEART, DISEASES OF). Drugs used for treatment can be classi?ed as follows: diuretics; vasodilator antihypertensives; centrally acting antihypertensives; adrenergic neurone-blocking drugs; alpha-adrenoreceptorblocking drugs; drugs affecting the renin-angiotensin system; ganglion-blocking drugs; and tyrosine hydroxylase inhibitors. The drugs prescribed depend on many factors, including the type of hypertension being treated. Treatment can be di?cult because of the need to balance the e?ectiveness of a drug in reducing blood pressure against its side-effects.... antihypertensive drugs

One third of those taking tranquillisers become addicted. One of the problems of psychological dependence is the discomfort of withdrawal symptoms.

Symptoms. Tremors, restlessness, nausea and sleep disturbance. The greater potency of the drug, the higher the rebound anxiety. Many drugs create stress, weaken resistance to disease, tax the heart and raise blood sugar levels.

Drugs like Cortisone cause bone loss by imperfect absorption of calcium. Taken in the form of milk and dairy products, calcium is not always absorbed. Herbs to make good calcium loss are: Horsetail, Chickweed, Slippery Elm, Spinach, Alfalfa.

Agents to calm nerves and promote withdrawal may augment a doctor’s prescription for reduction of drug dosage, until the latter may be discontinued. Skullcap and Valerian offer a good base for a prescription adjusted to meet individual requirements.

Alternatives. Teas: German Chamomile, Gotu Kola, Hops, Lime flowers, Hyssop, Alfalfa, Passion flower, Valerian, Mistletoe, Oats, Lavender, Vervain, Motherwort. 1 heaped teaspoon to each cup boiling water; infuse 5-15 minutes; half-1 cup thrice daily.

Decoctions: Valerian, Devil’s Claw, Siberian Ginseng, Lady’s Slipper. Jamaica Dogwood, Black Cohosh.

Tablets/capsules. Motherwort, Dogwood, Valerian, Skullcap, Passion flower, Mistletoe, Liquorice. Powders. Formulae. Alternatives. (1) Combine equal parts Valerian, Skullcap, Mistletoe. Or, (2) Combine Valerian 1; Skullcap 2; Asafoetida quarter. Dose: 500mg (two 00 capsules or one-third teaspoon) thrice daily. Formula No 2 is very effective but offensive to taste and smell.

Practitioner. Tincture Nucis vom. once or twice daily, as advised.

Aloe Vera gel (or juice). Russians tested this plant on rabbits given heavy drug doses and expected to die. Their survival revealed the protective property of this plant: dose, 1 tablespoon morning and evening. Aromatherapy. Sniff Ylang Ylang oil. Lavender oil massage for its relaxing and stress-reducing properties.

Diet. Avoid high blood sugar levels by rejecting alcohol, white flour products, chocolate, sugar, sweets and high cholesterol foods.

Supplements. Daily. Multivitamins, Vitamin B-complex, B6, Vitamin C 2g, Minerals: Magnesium, Manganese, Iron, Zinc. Change of lifestyle. Stop smoking. Yoga.

Notes. “Do not withdraw: insulin, anticoagulants, epileptic drugs, steroids, thyroxin and hormone replacement therapy (the endocrine glands may no longer be active). Long-term tranquillisers e.g., Largactil or any medicament which has been used for a long period. Patients on these drugs are on a finely-tuned medication the balance of which may be easily disturbed.” (Simon Mills, FNIMH)

ARRHYTHMIA is a variation in the normal rhythm of the heartbeat. Management of the condition requires accurate diagnosis of the type, and ELECTROCARDIOGRAPHY is vital in this process (see HEART, DISEASES OF). Drug treatment is usually part of the management, and antiarrhythmic drugs can be divided clinically into those that act on supraventricular arrhythmias, those that act on both supraventricular and ventricular arrythmias, and those that act on ventricular arrythmias. Respective examples are VERAPAMIL, DISOPYRAMIDE and LIDOCAINE. This large group of drugs can also be classi?ed according to their effects on the electrical reactions of active myocardial cells. The many drugs available are described in the British National Formulary.... antiarrhythmic drugs

These widely used drugs include a range of different preparations which relieve DEPRESSION. All the antidepressants available at the time of writing are more or less equally e?ective. In studies where patients agree to take either antidepressants or identical dummy PLACEBO pills (without knowing which), at least two-thirds of those who receive antidepressants feel much better within three months, while fewer than one-third of those on placebos recover naturally in the same period. In general these drugs are useful for severe and moderate depression including postnatal illness; they are not e?ective in milder forms of depression although they may be tried for a short time if other therapies have failed.

The most widely prescribed type of antidepressants are the tricyclics, so-called because their molecular structure includes three rings. The other commonly used types are named after the actions they have on chemicals in the brain: the SELECTIVE SEROTONIN-REUPTAKE INHIBITORS (SSRIS) and the MONOAMINE OXIDASE INHIBITORS (MAOIS) – see also below. All types of antidepressant work in similar ways. Tricyclic antidepressants have cured depression in millions of people, but they can cause unpleasant side-effects, particularly in the ?rst couple of weeks. These include SEDATION, dry mouth, excessive sweating, CONSTIPATION, urinary problems, and impotence (inability to get an erection). Up to half of all people prescribed tricyclic drugs cannot tolerate the side-effects and stop treatment before their depression is properly treated. More seriously, tricyclics can upset the rhythm of the heart in susceptible people and should never be given in the presence of heart disease.

The SSRIs are newer, coming into wide use in the late 1980s. They increase the levels in the brain of the chemical messenger SEROTONIN, which is thought to be depleted in depression. Indeed, the SSRIs are as e?ective as tricyclics and, although they can cause nausea and excessive sweating at ?rst, they generally have fewer side-effects. Their main disadvantage, however, is that they cost much more than the most commonly used tricyclic, amitriptyline. On the other hand, they are more acceptable to many patients and they cause fewer drop-outs from treatment – up to a quarter rather than a half. The money saved by completed, successful treatment may outweigh the prescribing costs. SSRIs have been reported as associated with an increased risk of suicide.

Another group of antidepressants, the MAOIs, have been in use since the late 1950s.

They are stimulants, rather than sedatives, and are particularly helpful for people who are physically and mentally slowed by depression. They work well but have one big disadvantage – a dangerous interaction with certain foods and other drugs, causing a sudden and very dangerous increase in blood pressure. People taking them must carry an information card explaining the risk and listing the things that they should avoid. Because of this risk, MAOIs are not used much now, except when other treatments have failed. A new MAOI, moclobemide, which is less likely to interact and so cause high blood pressure, is now available.

LITHIUM CARBONATE is a powerful antidepressant used for intractable depression. It should be used under specialist supervision as the gap between an e?ective dose and a toxic one is narrow.

St John’s Wort is a popular herbal remedy which may be e?ective, but which is handicapped by di?erences of strength between di?erent preparations or batches. It can interact with a number of conventional drugs and so needs to be used cautiously and with advice.

In general, antidepressants work by restoring the balance of chemicals in the brain. Improved sleep and reduced anxiety are usually the ?rst signs of improvement, particularly among people taking the more sedative tricyclic drugs. Improvement in other symptoms follow, with the mood starting to lift after about two weeks of treatment. Most people feel well by three months, although a few residual symptoms, such as slowness in the mornings, may take longer to clear up. People taking antidepressants usually want to stop them as soon as they feel better; however, the risk of relapse is high for up to a year and most doctors recommend continuing the drugs for around 4–6 months after recovery, with gradual reduction of the dose after that.

Withdrawal reactions may occur including nausea, vomiting, headache, giddiness, panic or anxiety and restlessness. The drugs should be withdrawn gradually over about a month or longer (up to six months in those who have been on maintenance treatment).

A wide range of antidepressant drugs is described in the British National Formulary. Examples include:

Tricyclics: amitryptyline, imipramine, doxepin.

MAOIs: phenelzine, isocarboxazid.

SSRIs: citalopram, ?uoxetine, paraxtene. (Antidepressant drugs not in these three

groups include ?upenthixol, mertazapine and venlafaxine.)... antidepressant drugs

Dracontiasis, or dracunculiasis, is a nematode infection caused by Dracunculus medinensis (guinea-worm). The major clinical problem is secondary infection of the worm track, causing CELLULITIS, SYNOVITIS, epididymo-ORCHITIS, periarticular FIBROSIS, and ARTHRITIS; TETANUS is a potentially lethal complication. CHEMOTHERAPY is unsatisfactory and the time-honoured method of extracting the female adult by winding it around a matchstick remains in use. Surgical treatment may be necessary. Ultimate prevention consists of removing Cyclops spp. from drinking water.... dracontiasis

Antihistamine drugs antagonise the action of HISTAMINE and are therefore of value in the treatment of certain allergic conditions (see ALLERGY). They may be divided into those with a central action (e.g. ?upheniramine and cyclizine) and those such as loratidine and terfenadine with almost no central action. Antihistamines are also of some value in the treatment of vasomotor RHINITIS (see also under NOSE, DISORDERS OF); they reduce rhinorrhoea and sneezing but are usually less e?ective in relieving nasal congestion. All antihistamines are useful in the treatment of URTICARIA and certain allergic skin rashes, insect bites and stings, as well as in the treatment of drug allergies. Chlorpheniramine or promethazine injections are useful in the emergency treatment of angio-oedema (see under URTICARIA) and ANAPHYLAXIS.

There is little evidence that any one antihistamine is superior to another, and patients vary considerably in their response to them. The antihistamines di?er in their duration of action and in the incidence of side-effects such as drowsiness. Most are short-acting, but some (such as promethazine) work for up to 12 hours. They all cause sedation but promethazine, trimeprazine and dimenhydrinate tend to be more sedating while chlorpheniramine and cyclizine are less so, as are astemizole, oxatomide and terfenadine. Patients should be warned that their ability to drive or operate machinery may be impaired when taking these drugs, and that the effects of ALCOHOL may be increased.... antihistamine drugs

A brief episode affecting the nervous system that causes the person to fall suddenly. There is no loss of consciousness. The loss of tone in the muscles, responsible for the fall, may persist for several hours; in such cases moving the patient or applying pressure to the soles of the feet may restore muscle tone. In most cases, however, recovery is immediate. The cause is probably a temporary interference with the blood supply to the brain. In others there may be some disturbance of the vestibular apparatus which controls the balance of the body. (See EAR, DISEASES OF; TRANSIENT ISCHAEMIC ATTACKS OR EPISODES (TIA, TIE).)... drop attack

A group of drugs, also known as thrombolytics, with the ability to break down the protein FIBRIN, the prime constituent of blood clots (see THROMBUS; THROMBOSIS). They are used to disperse blood clots that have formed in the vessels of the circulatory system. The group includes STREPTOKINASE, alteplase and reteplase. The drugs work by activating PLASMINOGEN to form PLASMIN which degrades ?brin and breaks up the blood clot (see COAGULATION).... fibrinolytic drugs

A technique for ?xating specimens of tissue, involving a minimum of chemical and physical alteration. The histological specimen is immersed in a chemical, isopentane, which has been cooled in liquid air to a temperature just below 200 °C. This preserves the tissue instantly without large ice crystals forming – these would result in structural damage. The specimen is then dehydrated in a vacuum for three days, after which it can be examined using a MICROSCOPE.... freeze drying

A variety of drugs with di?ering actions are available for the treatment of peptic ulcer, the composite title covering gastric ulcer (see STOMACH, DISEASES OF) and DUODENAL ULCER. Peptic ulceration may also involve the lower OESOPHAGUS, and after stomach surgery the junction of the stomach and small intestine.

The drugs used in combination are:

The receptor antagonists, which reduce the output of gastric acid by histamine H2receptor blockade; they include CIMETIDINE, FAMOTIDINE and RANITIDINE.

ANTIBIOTICS to eradicate Helicobacter pylori infection, a major cause of peptic ulceration. They are usually used in combination with one of the PROTON-PUMP INHIBITORS and include clarithomycin, amoxacillin and metronidazole.

A group of drugs used to treat diabetes mellitus, in which a lack of insulin, or resistance to its actions, results in raised blood glucose levels. A wide range of antidiabetics are used to keep the blood glucose level as close to normal as possible, and consequently reduce the risk of complications such as vascular (blood vessel) disease.

Antidiabetic drugs include insulin, which must be administered by injection, and oral hypoglycaemics such as glibenclamide and metformin. Acarbose and guar gum reduce or slow absorption of carbohydrate from the intestines after meals. Repaglinide stimulates insulin release from the pancreas for a short time and may be taken directly before meals. Rosiglitazone reduces resistance to the effects of insulin in the tissues and may be used together with other hypoglycaemics.... antidiabetic drugs

opiates such as cocaine and morphine, amfetamine drugs, and barbiturate drugs. controlled trial A method of testing the effectiveness of new treatments or comparing different treatments. In a typical controlled drug trial, 2 comparable groups of patients suffering from the same illness are given courses of apparently identical treatment. However, only one group receives the new treatment; the second control group is given a placebo. Alternatively, the control group may be given an established drug that is already known to be effective. After a predetermined period, the 2 groups are assessed medically. Controlled trials must be conducted “blind’’ (the patients do not know which treatment they are receiving). In a “double-blind’’ trial, neither the patients nor the doctors who assess them know who is receiving which treatment. contusion Bruising to the skin and underlying tissues from an injury. convalescence The recovery period following an illness or surgery during which the patient regains strength before returning to normal activities.... controlled drug

When a new drug is introduced, it has usually been studied only in relatively few patients – typically 1,500. If n patients have been studied, and no serious effects observed, there is still a chance of a serious adverse e?ect occurring in the general population as frequently as 3/n (1:500).

Adverse effects can be divided into types. First, those which are closely related to the concentration of the drug and accord with what is known of its PHARMACOLOGY. These so-called type A (augmented pharmacological) effects are distinguished from type B (bizarre) effects which are unpredictable, usually rare, and often severe. ANAPHYLAXIS is the most obvious of these; other examples include bone-marrow suppression with CO-TRIMOXAZOLE; hepatic failure (see HEPATITIS) with SODIUM VALPROATE; and PULMONARY FIBROSIS with AMIODARONE. A more comprehensive classi?cation includes reactions type C (chronic effects), D (delayed effects – such as teratogenesis or carcinogenesis) and E (end-of-dose effects – withdrawal effects). Examples of adverse reactions include nausea, skin eruptions, jaundice, sleepiness and headaches.

While most reported adverse reactions are minor and require no treatment, patients should remind their doctors of any drug allergy or adverse e?ect they have suffered in the past. Medical warning bracelets are easily obtained. Doctors should report adverse effects to the authorities – in the case of Britain, to the Committee on Safety of Medicines (CSM), using the yellow-card reporting machinery.... adverse reactions to drugs

Andrographis Tea is well known for its bitter taste, as well as for its healthy benefits. It has proven to be an adjuvant in treating severe illness such as hepatitis, due to its high content of antioxidants. Andrographis Tea description Andrographis is originating from Asia, being used for centuries in Ayurvedic medicine. The plant is easy to grow: its propagation is by seeds, planted during spring and summer. Andrographis grows both in full sun or shade, developing vigorously in moist conditions. The herb has been proved to treat infectious diseases. This fact was discovered during the global flu epidemic of 1919, known as one of the most destructive infectious to outbreak in history, which killed millions worldwide, in many countries. Andrographis Tea is the resulting beverage from brewing the andrographis plant. It is widely known for its bitter taste as well as for its adjuvant properties against flu, depression, digestion complaints, but not only. Andrographis Tea brewing To brew Andrographis tea:

• place 1 teaspoon of dried andrographis in a tea infuser (10 grams of fresh leaves)
• place the infuser in a tea cup
• cover it with 1 cup of boiling water
• steep the tea for 10 minutes
• drink it slowly

The resulting tea has an extreme bitter taste. Another possibility of enjoying the benefits of Andrographis tea is to intake capsules containing the plant. Andrographis Tea benefits Andrographis Tea has many proven benefits, such as:

• Treating gastrointestinal complains
• Treating throat infections
• Dispelling toxins
• Increasing biliary flow
• Treating coughs, headaches, edema
• Treating pain conditions, inflammation
• Treating arthritis, rheumatism
• Treating constipation
• Treating pneumonia, tuberculosis, leprosy, hepatitis, herpes, diabetes, bronchitis

Andrographis Tea side effects It has been showed that Andrographis Tea should not be used by pregnant and nursing women or by children. It has been also noticed that large doses of Andrographis Tea may lead to infertility. Andrographis Tea is a healthy beverage which has the ability to strengthen the immune system, stop cancer cells from multiplying, and also render a good physical state. It can be consumed as tea or medicinal pills.... andrographis tea: a drop of health

Black Dragon Pearl tea is a type of black tea that provides a full range of benefits to consumers of all ages, worldwide. It distinguishes itself through its chocolate taste and therapeutical benefits. Black Dragon Pearl Tea description Black Dragon Pearl tea, originating from the Chinese province Yunnan, is a type of unsteady black tea, well-known in the area. Each tea pearl contains thirty hand-picked leaves and buds which are immediately rolled to prevent leaves from drying. A morning or afternoon cup of Black Dragon Pearl tea together served with fruits may be a pleasant way to relax oneself. How to prepare Black Dragon Pearl Tea Black Dragon Pearl Black tea can be infused up to three times and still keeps its malty flavor. In case of steeping too long, like any black tea, it can get bitter. When brewed, it has a reddish-brown color, whose aroma makes it identifiable for the senses and, when drunk it has a very delicate and chocolaty taste. Black Dragon Pearl Black tea can be served with or without sugar (or honey) and milk. It contains a relatively low caffeine level. When preparing Black Dragon Pearl tea:

• Use 1 teaspoon of tea for 8 ounces of water ( 2ounces of tea equals 25-30 teaspoons)
• Heat water until it is almost boiling (195 degrees).
• Pour over the pearls.
• Steep them for 3 or 4 minutes.

Black Dragon Pearl Tea benefits Studies revealed the important qualities of Black Dragon Pearl tea. Like any type of black tea, this luxurious beverage contains antioxidants - proven adjuvants in treating cancer and stopping tumors growth. This type of tea has been associated to lowering the risk of stomach, colon and breast cancer, although the connection is not fully scientifically proven. Researchers claim that a compound in Black Dragon Pearl tea caused colorectal cancer cells to disappear, whereas normal cells were not affected by it. Black Dragon Pearl tea is also recommended in dealing with:

• poor arterial functioning that can cause heart attacks and strokes
• inflammation
• viruses
• cholesterol reduction
• teeth decay
• blood toxins removing
• aging effects

Black Dragon Pearl Tea side effects In case of intaking more than 3 cups of tea per day, headaches and dizziness can sometimes appear. Rarely, symptoms of upset stomach may follow Black Dragon Pearl tea consumption. A diet based on Black Dragon Pearl tea plays an important part in one’s life because it renders the sufficient quantity of antioxidants needed by human body to fight against a large array of diseases.... black dragon pearl tea

Also called beta blockers, these drugs interrupt the transmission of neuronal messages via the body’s adrenergic receptor sites. In the HEART these are called beta1 (cardioselective) receptors. Another type – beta2 (non-cardioselective) receptors – is sited in the airways, blood vessels, and organs such as the eye, liver and pancreas. Cardioselective beta blockers act primarily on beta1 receptors, whereas non-cardioselective drugs act on both varieties, beta1 and beta2. (The neurotransmissions interrupted at the beta-receptor sites through the body by the beta blockers are initiated in the ADRENAL GLANDS: this is why these drugs are sometimes described as beta-adrenergic-blocking agents.)

They work by blocking the stimulation of beta adrenergic receptors by the neurotransmitters adrenaline and noradrenaline, which are produced at the nerve endings of that part of the SYMPATHETIC NERVOUS SYSTEM – the autonomous (involuntary) network

– which facilitates the body’s reaction to anxiety, stress and exercise – the ‘fear and ?ight’ response.

Beta1 blockers reduce the frequency and force of the heartbeat; beta2 blockers prevent vasodilation (increase in the diameter of blood vessels), thus in?uencing the patient’s blood pressure. Beta1 blockers also affect blood pressure, but the mechanism of their action is unclear. They can reduce to normal an abnormally fast heart rate so the power of the heart can be concomitantly controlled: this reduces the oxygen requirements of the heart with an advantageous knock-on e?ect on the respiratory system. These are valuable therapeutic effects in patients with ANGINA or who have had a myocardial infarction (heart attack – see HEART, DISEASES OF), or who suffer from HYPERTENSION. Beta2 blockers reduce tremors in muscles elsewhere in the body which are a feature of anxiety or the result of thyrotoxicosis (an overactive thyroid gland – see under THYROID GLAND, DISEASES OF). Noncardioselective blockers also reduce the abnormal pressure caused by the increase in the ?uid in the eyeball that characterises GLAUCOMA.

Many beta-blocking drugs are now available; minor therapeutic di?erences between them may in?uence the choice of a drug for a particular patient. Among the common drugs are:

Primarily cardioselective	Non-cardioselective
Acebutolol	Labetalol
Atenolol	Nadolol
Betaxolol	Oxprenolol
Celiprolol	Propanolol
Metoprolol	Timolol

These powerful drugs have various side-effects and should be prescribed and monitored with care. In particular, people who suffer from asthma, bronchitis or other respiratory problems may develop breathing diffculties. Long-term treatment with beta blockers should not be suddenly stopped, as this may precipitate a severe recurrence of the patient’s symptoms – including, possibly, a sharp rise in blood pressure. Gradual withdrawal of medication should mitigate untoward effects.... beta-adrenoceptor-blocking drugs

In the United Kingdom, controlled drugs are those preparations referred to under the Misuse of Drugs Act 1971. The Act prohibits activities related to the manufacture, supply and possession of these drugs, and they are classi?ed into three groups which determine the penalties for o?ences involving their misuse. For example, class A includes COCAINE, DIAMORPHINE, MORPHINE, LSD (see LYSERGIC ACID DIETHYLAMIDE and PETHIDINE HYDROCHLORIDE. Class B includes AMPHETAMINES, BARBITURATES and CODEINE. Class C includes drugs related to amphetamines such as diethylpropion and chlorphentermine, meprobamate and most BENZODIAZEPINES and CANNABIS.

The Misuse of Drugs Regulations 1985 de?ne the classes of person authorised to supply and possess controlled drugs, and lay down the conditions under which these activities may be carried out. In the Regulations, drugs are divided into ?ve schedules specifying the requirements for supply, possession, prescribing and record-keeping. Schedule I contains drugs which are not used as medicines. Schedules II and III contain drugs which are subject to the prescription requirements of the Act (see below). They are distinguished in the British National Formulary (BNF) by the symbol CD and they include morphine, diamorphine (heroin), other opioid analgesics, barbiturates, amphetamines, cocaine and diethylpropion. Schedules IV and V contain drugs such as the benzodiazepines which are subject to minimal control. A full list of the drugs in each schedule can be found in the BNF.

Prescriptions for drugs in schedules II and III must be signed and dated by the prescriber, who must give his or her address. The prescription must be in the prescriber’s own handwriting and provide the name and address of the patient and the total quantity of the preparation in both words and ?gures. The pharmacist is not allowed to dispense a controlled drug unless all the information required by law is given on the prescription.

Until 1997 the Misuse of Drugs (Noti?cation and Supply of Addicts) Regulations 1973 governed the noti?cation of addicts. This was required in respect of the following commonly used drugs: cocaine, dextromoramide, diamorphine, dipipanone, hydrocodeine, hydromorphone, levorphanol, methadone, morphine, opium, oxycodone, pethidine, phenazocine and piritranide.

In 1997 the Misuse of Drugs (Supply to Addicts) Regulations 1997 revoked the 1973 requirement for noti?cation. Doctors are now expected to report (on a standard form) cases of drug misuse to their local Drug Misuse Database (DMD). Noti?cation by the doctor should be made when a patient ?rst presents with a drug problem or when he or she visits again after a gap of six months or more. All types of misuse should be reported: this includes opioids, benzodiazepines and central nervous system stimulants. The data in the DMD are anonymised, which means that doctors cannot check on possible multiple prescribing for drug addicts.

The 1997 Regulations restrict the prescribing of diamorphine (heroin), Diconal® (a morphine-based drug) or cocaine to medical practitioners holding a special licence issued by the Home Secretary.

Drugs are usually administered distant to their site of action in the body; they must then pass across cell membranes to reach their site of action. For example, drugs given by mouth must pass across the gut membrane to enter the bloodstream and then pass through the endothelium of vessel walls to reach the site of action in the tissues. This process is called absorption and may depend on lipid di?usion, aqueous di?usion, active transport, or pinocytosis – a process in which a cell takes in small droplets of ?uid by cytoplasmic engulfment.... drug absorption

One of the most popular drinks in China, Dragon Well tea is part of the green teas family, having an inviting and a toasty flavor. A truly enjoyable and spectacular cup of tea.

Description of Dragon Well tea

Dragon Well tea is a type of pan-fried green tea, most commonly named Longjing tea from Hangzhou, Zheijang province in China, where is produced mainly by hand. During the production process, the Dragon Well is dried under a wood-fired Chinese pan called “wok”. This process removes the green, grassy taste and also inhibits enzyme activity. Due to the widespread opinion in China that the Dragon Well tea has a cooling effect, its popularity significantly increases especially during the spring and summer seasons. Often called the national tea of China, Dragon Well tea is often served to head of states and foreign delegations during their visits in China. Presented as a tribute to many generations, it was given even to Richard Nixon during his memorable encounter with Mao Zedong. This tea is very popular because of its unique properties:  jade color, vegetative aroma, mellow chestnut flavor and singular shape. It has a buttery, nutty, rich texture and an enjoyable dry finish. Commonly, Dragon Well tea is graded using a scale of six levels from superior quality to low quality so it is advisable to chose wisely when you decide to buy it. When the flavor can barely be sensed, it is clear that you deal with a poor quality.

How to store the Dragon Well tea

If the tea is sealed, keep it in a freezer. Cover with a box to insulate from temperature change. In order to get warm, leave it to room temperature before opening. This prevents condensation. After opening the package of Dragon Well tea, it is best to keep it away from light, moisture, smell and heat in an airtight container.

Ingredients of Dragon Well tea

Like most green teas, the Dragon Well tea contains amino acids, vitamins, flavonoids, proteins, calcium, iron, fluorine, theine and has one of the highest concentrations of catechins among teas, second only to white teas.

How to brew Dragon Well tea

When it comes to brewing Dragon Well tea, the best choice is a clear glass teacup, so that you can see the beauty of the leaves as they dance and unfurl in the water. It is really spectacular. Quality of tea is related directly to the beauty of the buds. Glass is most suitable also because it disperses heat quickly and prevents over-steeping. If you see that the buds have reached the bottom, this means that the tea is ready to drink. You should infuse a small amount of leaves in high temperature water for as long as it takes. Pour hot water at approximately 80 - 90 degrees Celsius. Immerse until most of the tea buds has sink to the bottom of the glass and the tea liquor turns yellow. This will take 5 to 10 minutes for the first infusion. During soaking, the tea brings out a soft, pure aroma, a yellow-green color and a rich flavor. Decant and leave a small quantity as you may use it as the seed for the next infusion. Infuse for another 2 to 4 times with progressively shorter steeping time.

Health Benefits of Dragon Well tea

All tea comes from the same plant named Camellia sinensis. The method of production creates the different types of tea. Dragon Well tea contains the highest content of antioxidant compounds. Antioxidants are proven to fight against certain cancers, lower cholesterol levels and blood pressure, reduce the likely-hood of getting the flu and other infections, boosting the immune function of our body and help reduce the signs of aging. It is also a fat burning accelerator so let’s not forget its important benefits for diets. There’s also enough fluoride found in green tea to aid against plaque and other oral bacteria.

Side effects of Dragon Well tea

Like any other green tea, Dragon Well tea may have few side effects like restlessness, palpitations, insomnia, anxiety, irritability, increased heart rate, and elevated blood pressure due to the caffeine content. It may also cause pain in the stomach area or reduce the body’s absorption of iron by 25% so it is contraindicated to people with anemia, faintness, gastritis with hyperacidity, stomach and duodenal ulcer.

Many patients are on several prescribed drugs, and numerous medicines are available over the counter, so the potential for drug interaction is large. A drug may interact with another by inhibiting its action, potentiating its action, or by simple summation of effects.

The interaction may take place:

(1) Prior to absorption or administration – for example, antacids bind tetracycline in the gut and prevent absorption.

(2) By interfering with protein binding – one drug may displace another from binding sites on plasma proteins. The action of the displaced drug will be increased because more drug is now available; for example, anticoagulants are displaced by analgesics.

(3) During metabolism or excretion of the drug – some drugs increase or decrease the activity of liver enzymes which metabolise drugs, thus affecting their rate of destruction; for example, barbiturates, nicotine, and alcohol all activate hepatic enzymes. Altering the pH of urine will affect the excretion of drugs via the kidney.

(4) At the drug receptor – one drug may displace another at the receptor, affecting its e?cacy or duration of action.... drug interactions

These are natural products or synthetic chemicals that can alter the way in which the body works, or be used to prevent or treat disease. One or more drugs, combined with stabilisers, colourings, and other ingredients, make(s) up a medicine for practical use in treating patients. (See DEPENDENCE; MEDICINES.) In Britain, the supply of drugs is controlled by the Medicines Act. Some drugs are available only on prescription; some both on prescription and over the counter; and some are not available on NHS prescription. When enquiring about drugs that a patient is taking, it is essential to ask about all items bought over the counter and any herbal or traditional remedies that might be used, as these can interact with other prescribed drugs (see DRUG INTERACTIONS) or affect the patient’s presenting complaints. Each drug has a single generic name, but many will also have several proprietary (brand) names. It is often much cheaper to prescribe the generic form of a drug, and many doctors do so. Many hospitals and general practices in the United Kingdom now provide a list of suggested drugs for doctors to prescribe. If a doctor wishes to use a drug not on the list, he or she must give a valid reason.

Prescriptions for drugs should be printed or written clearly in ink and signed and dated by the prescriber (computer-generated facsimile signatures do not meet legal requirements). They should include the patient’s name, address and age (obligatory for children under 12), the name of the drug to be supplied, the dose and dose frequency, and the total quantity to be supplied. Any special instructions (e.g. ‘after food’) should be stated. There are special regulations about the prescription of drugs controlled under the Misuse of Drugs Regulations 1985 (see CONTROLLED DRUGS). A pharmacist can advise about which drugs are available without prescription, and is able to recommend treatment for many minor complaints. Information about exemption from prescription charges in the NHS can be obtained from health visitors, general practitioners, or social security o?ces.... drugs

About Pau D’Arco Tea Pau D’Arco tea uses the inner bark of the Pink Ipê tree, also known as Pink Lapacho. The tree can be found in many South American countries. The Pink Lapacho is a large tree which can grow up to 30m tall. Usually, the trunk represents a third of that height, while the rest is used by the tree’s branches. The bark is dark brown, tough and hard to peel, and its branches spring up with opposite and petiolate leaves, and large, tubular-shaped pink flowers which bloom between July and September. How to make Pau D’Arco Tea To enjoy some pau d’arco tea, add 3 tablespoons to a pot containing 1 liter of water and bring it to boiling point. Once it reaches boiling point, lower the heat to medium-low and leave it like this for about 20 minutes. Once that’s done, strain the tea and pour it into cups. Pau d’arco tea can be served both hot and cold. If you want to, you can sweeten it with honey, stevia or fruit juice. Pau D’Arco Tea Benefits The inner bark of the Pink Lapacho tea has important active constituents, such as lapachol, lapachone and isolapachone, as well as various flavonoids and tannins. They are transferred to the pau d’arco tea; this way, the beverage helps us stay healthy. Pau d’arco tea plays an important role in the help against cancer.

Although researches are still being made in this area, it is recommended in the treatment for leukemia, anemia and other blood disorders. Pau d’arco tea is also useful in fighting fungi. It is used to treat yeast infection and candida, due to its antifungal nature. It can help in the treatment for stomach ulcers, tuberculosis, pneumonia, and dysentery. It also protects you against tropical diseases (malaria, schistosomiasis). Pau D’Arco Tea Side Effects Pau d’arco tea may act like a blood thinner.

If you drink more, it might lead to nausea, vomiting or bleeding (in which case you should consult a doctor). Other symptoms include headaches, dizziness and diarrhea. Pau d’arco tea has lots of important health benefits, but it also has a few side effects which you should remember. If you make sure it’s safe to drink this tea, you can enjoy it with no worries!... drink pau d’arco tea from south america

Unnecessary drugs during pregnancy should be avoided because of the adverse e?ect of some drugs on the fetus which have no harmful e?ect on the mother. Drugs may pass through the PLACENTA and damage the fetus because their pharmacological effects are enhanced as the enzyme systems responsible for their degradation are undeveloped in the fetus. Thus, if the drug can pass through the placenta, the pharmacological e?ect on the fetus may be great whilst that on the mother is minimal. WARFARIN may thus induce fetal and placental haemorrhage and the administration of THIAZIDES may produce THROMBOCYTOPENIA in the newborn. Many progestogens have androgenic side-effects and their administration to a mother for the purpose of preventing recurrent abortion may produce VIRILISATION of the female fetus. Tetracycline administered during the last trimester commonly stains the deciduous teeth of the child yellow.

The other dangers of administering drugs in pregnancy are the teratogenic effects (see TERATOGENESIS). It is understandable that a drug may interfere with a mechanism essential for growth and result in arrested or distorted development of the fetus and yet cause no disturbance in the adult, in whom these di?erentiation and organisation processes have ceased to be relevant. Thus the e?ect of a drug upon a fetus may di?er qualitatively as well as quantitatively from its e?ect on the mother. The susceptibility of the embryo will depend on the stage of development it has reached when the drug is given. The stage of early di?erentiation – that is, from the beginning of the third week to the end of the tenth week of pregnancy – is the time of greatest susceptibility. After this time the risk of congenital malformation from drug treatment is less, although the death of the fetus can occur at any time.... drugs in pregnancy

If you’ve decided to go on a diet in order to lose weight, you have to be careful with what you drink and eat. Sodas and some juices are a definite no, and while you can drink water all the time, it might get a bit dull. If you want to try something different, and especially pleasant to the taste, tea’s the best choice. Find out more about the perfect teas for weight loss. Benefits of tea for weight loss If you drink your tea simple, without sugar, then you’ll enjoy a hot beverage with 0 calories. This at least prevents you from gaining weight. However, based on the effect one type of tea may have on the digestive system, drinking tea can even help you lose weight. From green tea to oolong tea, each has its own health benefits which help you when you’re on a diet. Types of tea for weight loss First of all, green tea is perfect when you’re on a diet. Among its active constituents, green tea has catechin polyphenols, which is quite useful when you want to lose weight. Thanks to this, drinking green tea will increase thermogenesis (the amount of calories which are burned) and fat oxidation. You can drink 4-5 cups of tea a day. Oolong tea is also helpful if you’re on a diet. It even has a stronger effect than green tea, by speeding up the body’s metabolism and promoting fat burning. If you include it in your diet, don’t drink more than two cups a day. Peppermint tea is included on the list of teas you can drink while on a diet. Besides the fact that it promotes a good digestion, it helps you burn calories as it speeds up the digestive process. Other teas that help you lose weight include star anise tea, rose petal tea, as well as various types of herbal teas. Tea Steeping Time Steeping time varies from one type of tea to another. If you use teabags, follow the instructions written on the box. If you use dried leaves to make your tea for weight loss, then here are a few steeping instructions. If you’re drinking green tea, it’s best that you let it steep for about 3 minutes. Steeping time for oolong tea can vary from one minute to 5, based on how strong you want the tea’s flavor to be. And as for peppermint tea, you should let it steep for about 4-5 minutes. Tips to sweeten your diet tea If you want to sweeten your tea even when on a diet, you mustn’t use sugar or milk, even if you like those the best. While they won’t add weight, they also won’t help you lose it. The best solution, in this case, is for you to use honey. Other things you can use to sweeten it are fruit juices (especially lemon juice) and stevia leaves. Based on your preferences and the taste of the tea you choose, you can even combine them. Caffeine in tea and weight loss The caffeine found in various types of tea also helps you lose weight. Caffeine acts as a stimulant; therefore it gives you more energy. The more energetic you feel, the more you’re bound to exercise in order to burn more fats. Also, as it acts as a stimulant, it can help reduce your appetite. Caffeine might not be the only stimulant you’ll find in teas. Other stimulants include ginseng, taurine, and guarnine. Side effects related to weight loss tea People who know coffee doesn’t do them good should be careful with teas that contain caffeine. It can cause unpleasant side effects, such as insomnia, anxiety, headache, dizziness, irritability, blurred vision and skin rashes. When you combine your diet tea with a different alimentation and exercising, the side effects might become more unpleasant. Also, make sure you check the amount of tea that’s recommended for drinking. You can have 4-5 cups of green tea per day, while in the case of oolong tea, it is advised that you drink two cups. The amount varies from one tea to another. Now, drinking tea for weight loss sounds like a tempting idea. Considering how helpful tea can be when you’re trying to lose weight, make sure you pick one when you go on a diet.... drink tea for weight loss

These drugs reduce the amount of low-density LIPOPROTEINS, which transport CHOLESTEROL and triglycerides (see TRIGLYCERIDE) in the blood, or raise the concentration of high-density lipoproteins. The aim is to reduce the progression of ATHEROSCLEROSIS and therefore help prevent coronary heart disease (see HEART, DISEASES OF). These drugs should be combined with reducing other risk factors for raised lipid concentrations, such as a high-fat diet, smoking and obesity. Lipid-regulating drugs include STATINS, ?brates, anion-exchange resins, and NICOTINIC ACID, which may be used singly or in combination under careful medical supervision (see HYPERLIPIDAEMIA).... lipid-regulating drugs

Women need to be careful both with what they eat and drink during pregnancy. Even if tea is generally recommended as an everyday beverage, most teas shouldn’t be drunk during pregnancy. Find out which teas you should and shouldn’t drink when you’re pregnant. Careful with teas for pregnancy There are various reasons why pregnant women should be careful with the type of tea they drink. Many are related to the caffeine content some tea varieties might have. Drinking tea with caffeine content might lead to birth defects or even unwanted miscarriages. Also, other tea varieties can lead to uterine contractions, or have properties that involve regulating menstruation. These can also lead to miscarriages. That doesn’t mean that, during pregnancy, women should completely stay away from teas. They just have to know what type of tea they can drink. Teas you can drink for pregnancy Rooibos tea is often recommended to pregnant women, as it doesn’t contain caffeine at all. It contains antioxidants, as well as a low level of tannins. Thanks to this, they are less likely to interfere with iron absorption and, therefore, cause anemia during and after pregnancy. It also helps with indigestion and may relieve nausea. Pregnant women can drink ginger tea or mint tea, which help with morning sickness, or chamomile tea to prevent insomnia. Also, nettle tea can be drunk during the second and third trimester of the pregnancy (not the first) only if it’s made from nettle leaves and not from the root. Raspberry leaf tea has many benefits related to pregnancy. First of all, if a woman wants to get pregnant, this tea will increase fertility, as well as strengthen the uterine wall and relax the muscle in the uterus. During pregnancy, it helps with leg cramps, morning sickness and diarrhea. Also, drinking this tea may lead to less artificial ruptures in the membranes, which lowers the chances of needing a caesarean delivery, as well as needing forceps or vacuum birth. Teas you shouldn’t drink for pregnancy Even if teas are usually considered to be good for our health, this isn’t the case. Women should be careful not to drink various types of tea for pregnancy. It is considered best for pregnant women not to drink teas that contain caffeine. Teas made from the Camellia sinensis plant (green tea, black tea, white tea, oolong tea) contain caffeine, so it is best to avoid them. Small amounts may be acceptable, however it can still be risky, as they might still lead to birth defects or miscarriages. Pregnant women should also be careful with herbal teas. The varieties they shouldn’t drink include devil’s claw, ephedra, fenugreek, gentian, ginseng, hawthorne, motherwort, red raspberry leaf, senna, shepherd’s purse, St. John’s wort, or yarrow. Teas for labor Partridge tea is recommended for pregnant women who are due to give birth. It is recommended to be drunk during the last 2-3 weeks of pregnancy. Partridge tea helps with relieving congestions of the uterus and ovaries. It can also be used as an antiseptic to treat vaginal infections. Plus, when it is combined with raspberry leaves, it can help even more during the last two weeks of pregnancy. Pregnant women should be careful even when it comes to the type of tea they drink. Some might be harmful, while others may help them a lot both during and after pregnancy. If you want to get pregnant, make sure you remember the accepted teas for pregnancy.... drinking tea for pregnancy

See also MEDICINES. Government legislation covers the manufacture, sale and prescription of drugs in the UK. As well as stating which drugs may be sold over the counter (OTC) without a doctor’s or dentist’s prescription, and those which can be obtained only with such a prescription, government regulations determine the extent of availability of many substances which are liable to be abused – see Misuse of Drugs Act 1971 (below). The Misuse of Drugs Regulations 1985 de?ne those individuals who in their professional capacity are authorised to supply and possess controlled drugs: see the schedules of drugs listed below under the 1985 regulations.

Misuse of Drugs Act 1971 This legislation forbids activities relating to the manufacture, sale and possession of particular (controlled) drugs. These are classi?ed into three grades according to their dangers if misused. Any o?ences concerning class A drugs, potentially the most damaging when abused, carry the toughest penalties, while classes B and C attract lesser penalties if abused.

Class A includes: cocaine, dextromoramide, diamorphine (heroin), lysergic acid (LSD), methadone, morphine, opium, pethidine, phencyclidine acid and injectable preparations of class B drugs.

Class B includes: oral amphetamines, barbiturates, codeine, glutethimide, marijuana (cannabis), pentazocine and pholcodine.

Class C includes: drugs related to the amphetamines, anabolic and androgenic steroids, many benzodiazepines, buprenorphine, diethyl propion, human chorionic gonadotrophin (HCG), mazindol, meprobamate, pemoline, phenbuterol, and somatropin.

Misuse of Drugs Regulations 1985 These regulations de?ne those people who are authorised in their professional capacity to supply and possess controlled drugs. They also describe the requirements for legally undertaking these activities, such as storage of the drugs and limits on their prescription.

Drugs are divided into ?ve schedules and some examples follow.

I: Almost all are prohibited except in accordance with Home O?ce authority: marijuana (cannabis), LSD.

II: High potential for abuse but have

accepted medical uses: amphetamines, cocaine.

III: Lower potential for abuse: barbiturates, meprobamate, temazepam.

IV: Lower potential for abuse than I to III. Minimal control: benzodiazepines.

V: Low potential for abuse: generally compound preparations containing small amounts of opioids: kaolin and morphine (antidiarrhoeal medicine), codeine linctus (cough suppressant).

Green tea is considered a “wonder drug” because of its healthy contribution in human diets. Its antioxidant properties fight successfully against cancer, but not only. Green tea description Green tea is made from Camellia sinensis, an Asian plant, originating from China, Japan and South Korea. Oolong tea and black tea are prepared from the same plant as the green tea. A special feature of this type of tea is the ability to block the natural process of fermentation: after being picked, its leaves are steamed, dried and then rolled, thus blocking fermentation. Due to its constituents, it acts as an antioxidant, diuretic, cerebral and fattening burning stimulator, and also as a cancer protector. Green tea has been the subject of many scientific and medical studies so as to determine its health benefits. It seems that regular green tea drinkers may have a lower risk of developing heart diseases and certain types of cancer. There are several types of green tea available on the market: Bancha Tea, Chun Hao Tea , Dao Ren Tea , Dragonwell Tea , Genmaicha Tea , Gunpowder , Gyokuro Tea , Hojicha Tea , Kai Hua Long Ding Tea, Kukicha Tea , Matcha Tea , Sencha Tea , White Monkey Tea. Green Tea brewing To prepare green tea, use: two grams of tea per 100ml of water, or one teaspoon of green tea per five ounce cup. Green tea steeping time varies from thirty seconds to two, three minutes. The temperature differs as well, from 140°F to 190°F. Consumers recommend that lower-quality green teas to be steeped hotter and longer and higher-quality teas to be steeped cooler and shorter. In case of steeping the green tea too hot or too long, the resulting beverage is bitter and astringent. Green Tea benefits Green Tea lowers the risk of cancer. Studies have shown the green tea’s contribution against tumors growth, due to its high content of antioxidants, able to fight free radicals which are responsible for cancer spreading. Green Tea lowers the risk of stroke and heart diseases. The formation of blood clots (or thrombosis) is the main cause of the heart attacks and strokes. Green Tea has been acknowledged to exhibit abnormal blood clot formation. Green Tea lowers blood pressure. Green Tea is proven to block the effects of an enzyme secreted by the kidneys, considered to be one of the main causes of hypertension. Green Tea prevents tooth decay. Dental plaque and bacterial colonies that occur on the tooth surfaces and cause tooth decay can be inhibited by one of the compounds of the green tea. Also, this beverage has been shown to be effective against fighting gum diseases. Green Tea inhibits viruses Studies revealed that green tea can kill certain bacteria and staphs. It blocks the development of several viruses such as viral hepatitis. Green tea has also been successful in:

• Slowing early aging;
• Diets;
• The treatment of physical or intellectual fatigue;
• Treating fast cold and flu recovery;
• Preventing allergenic reactions;
• Balancing body fluids;
• Improving the immune function of the epidermis;
• Preventing and mending arthritis;
• Improving bone structure

Green Tea side effects Green tea is not recommended to patients suffering from high blood pressure, gastric acid secretion, gastritis and ulcer. Due to the amount of caffeine contained, scientists advise a reduced consumption of green tea for pregnant and nursing women. Also, this tea should not be drunk after 5 p.m., because the consumption may lead to insomnia, palpitations and agitation. Green tea is a well known beverage, especially due to its medicinal contribution to a large array of diseases such as arthritis, heart diseases and several types of cancer.... green tea or the wonder drug

These act by inhibiting the formation of PROSTAGLANDINS which are mediators of INFLAMMATION. They act both as ANALGESICS to relieve pain, and as inhibitors of in?ammation. Aspirin is a classic example of such a compound. Newer compounds have been synthesised with the aim of producing fewer and less severe side-effects. They are sometimes preferred to aspirin for the treatment of conditions such as RHEUMATOID ARTHRITIS, OSTEOARTHRITIS, sprains, strains and sports injuries. Their main side-effects are gastrointestinal: gastric ulcers and gastric haemorrhage may result (see STOMACH, DISEASES OF). This is because prostaglandins are necessary for the production of the mucous protective coat in the stomach and, when the production of prostaglandin is inhibited, the protection of the stomach is compromised. NSAIDs should therefore be used with caution in patients with DYSPEPSIA and gastric ulceration. The various nonsteroidal anti-in?ammatory drugs di?er little from each other in e?cacy, although there is considerable variation in patient response. Ibuprofen is one of the ?rst choices in this group of drugs as it combines good e?cacy with a low incidence of side-effects and administration is only required twice daily. Other drugs in this series include diclofenac, fenbufen, fenclofenac, fenoprofen, feprazone, ?urbiprofen, indomethacin, indoprofen, ketoprofen, ketorolac, naproxen, piroxicam, sulindac, tiaprofenic acid and tolmetin.... non-steroidal anti-inflammatory drugs (nsaids)

The COMMITTEE ON SAFETY OF MEDICINES (CSM) has the function of scrutinising the e?cacy, quality and safety of new DRUGS before clinical trials and before marketing, as well as the surveillance of each drug after marketing so that adverse reactions are monitored and documented, and warnings issued as required. Early clinical trials of a drug can only be carried out after a clinical-trial certi?cate has been issued by the licensing authority.

The major defect in this system is the dif?culty in obtaining reports of adverse reactions. Evidence suggests that at most, about 10 per cent of such reactions are reported. One method of trying to obtain this information is the ‘yellow card’ system. It is so called because it is based on the distribution of yellow cards to all doctors, pharmacists and dentists, on which they are asked to report any adverse reaction happening to someone taking a drug, whether or not they think it is the cause. Alternatively the CSM has a Freephone line and on-line computer facilities (ADROIT) for practitioners to use. Even though the annual number of adverse reactions reported in this way has risen from around 5,000 in 1975 to more than 18,000, this is probably fewer than the number actually occurring.

Two further committees in this safety screen are the Joint Committee on Vaccination and Immunisation and the Adverse Reactions to Vaccines and Immunological Substances Committee.... safety of drugs

These drugs stimulate the activity of the SYMPATHETIC NERVOUS SYSTEM. There are three groups: inotropic and vasoconstrictor sympathomimetics, and those used for cardiopulmonary resuscitation. The properties of these drugs vary according to whether they act on alpha or beta adrenergic receptors.

Inotropics act on beta receptors in heart muscle (see HEART), increasing its contractility and sometimes the heart rate. DOBUTAMINE and DOPAMINE are cardiac stimulants, while dopexamine acts on heart muscle and, via peripheral dopamine receptors, increases the excretion of URINE. ISOPRENALINE is used only as emergency treatment of heart block (interruption of the heart’s conduction) or severe slowing of the heart rate (bradycardia).... sympathomimetic drugs

Having a lucid dream means dreaming while being aware of the fact that you are dreaming. However, many people become lucid in the middle of the dream or, on the contrary, fall lose reality contact after being lucid at first. Although traditional medicine can’t be very helpful in these cases, alternative medicine has a few tricks up its sleeve. How a Tea for Lucid Dreams Works A Tea for Lucid Dreams’ main purpose is to make you recall what you have dreamed by calming your nervous system and improving your memory function. These teas are good for a number of other diseases, such as memory loss, headaches or migraines. However, talk to an herbalist or to your doctor before starting any kind of herbal treatment in order to make sure everything will be alright. Efficient Tea for Lucid Dreams In order to work properly, a Tea for Lucid Dreams needs to be both very efficient and one hundred percent safe (since lucid dreams are not exactly a medical problem, you may want to avoid developing one). A tea that is rich in antioxidants, nutrients, tannins, volatile oils and minerals (sodium, magnesium, iron, manganese) would be very adequate. You may want to avoid teas with a large amount of acid agents (they could cause stomach pain). If you don’t know which teas could be useful for lucid dreams, here’s a list for guidance: - Green Tea – contains all the ingredients necessary to sustain life, so it’s useful for a wide range of ailments, not just lucid dreams. If you’re suffering from infertility, anemia, asthenia, loss of appetite, digestive tract complaints or nervous system failure, this decoction could also be useful. However, you must avoid it at all costs if you’re experiencing some menstrual or menopausal symptoms. The same advice if you’re pregnant (it may cause uterine contractions and therefore miscarriage). - Valerian Tea – was been used as a sleep aid since ancient times, when the Romans and the Greeks took it before going to bed. This Tea for Lucid Dreams, thanks to its active compounds, is a mild sedative and could also work miracles on your nervous system. However, you need to make sure that you don’t exceed the number of cups recommended per day in order to avoid hallucinations, tiredness or even death. - Chamomile Tea – of course, the world’s greatest panacea shouldn’t be left aside. If you’re having trouble remembering your dreams, try a cup of Chamomile Tea before you go to bed! This Tea has a great fragrance and a pleasant smell. Plus, it’s one hundred percent safe so you can drink as much as you want. Tea for Lucid Dreams Side Effects When taken according to specifications, these teas are generally safe. However, exceeding the number of cups recommended per day may lead to a number of health problems, such as diarrhea, nausea, vomiting, upset stomach or even death! If you’ve been taking one of these decoctions for a while and you’re experience a negative response from your body, ask for medical assistance right away! Don’t take a Tea for Lucid Dreams if you’re pregnant, breastfeeding, on blood thinners or anticoagulants. The same advice in case you’re preparing for a surgery. If your doctor says it’s ok to start an herbal treatment, choose a tea that fits best your requirements and enjoy its wonderful benefits!  ... tea for lucid dreams

This group of drugs is one of three main types of drugs used to treat DEPRESSION, and was the ?rst to be introduced (in the 1950s). Tricyclic drugs work by blocking the re-uptake of the neurotransmitters SEROTONIN and NORADRENALINE (see NEUROTRANSMITTER), thus increasing the amount of the neurotransmitters at the nerve cell’s receptors. In people with depression, fewer neurotransmitters than normal are released, resulting in a slowing of neural activities. The drugs have a sedative e?ect, which can be useful for depressives with sleep problems, and an antimuscarinic action which can cause dry mouth and constipation (see ANTIMUSCARINE). Overdosage can produce COMA, ?ts (see SEIZURE) and irregular heart rhythm (ARRHYTHMIA). They are sometimes used for treating bed-wetting. (See also ANTIDEPRESSANT DRUGS.)... tricyclic antidepressant drugs

Dropsy of heart origin is distinguished from renal dropsy by an increase in oedema as the day proceeds. In the morning there may be no swelling but by the evening legs become swollen from the ankles upwards. Fluids stagnate in the tissues from inability of the heart to perform efficiently as a pump. The condition is a symptom of heart failure with increasing breathlessness which may lead to general dropsy.

Symptoms: worse after exercise, breathlessness, headache, general weakness, feeble pulse, pale face, skin cold, swollen tissues pit on pressure.

Drugs that are used to treat or prevent allergic reactions (see allergy). There are several groups, including corticosteroids, antihistamines, leukotriene receptor antagonists, and sodium cromoglicate.... antiallergy drugs

A group of drugs used to relieve the symptoms of anxiety. Benzodiazepine drugs and beta-blocker drugs are the 2 main types, although antidepressant drugs may occasionally be used. Benzodiazepine drugs promote mental and physical relaxation; they can also be used to treat insomnia, but their use for this purpose is avoided because they are addictive. Beta-blockers reduce only the physical symptoms of anxiety, such as shaking and palpitations, and are not addictive.... antianxiety drugs

A group of drugs used to treat and prevent abnormal blood clotting, to treat thrombosis, and to prevent and treat stroke and transient ischaemic attack. Anticoagulant drugs are also given to prevent abnormal blood clotting after major surgery (especially heart-valve replacement) or during haemodialysis (see dialysis). The most common anticoagulants are heparin and the newer heparin-derived drugs, such as tinzaparin, all of which have to be given by injection, and warfarin, which is taken orally.

Excessive doses of anticoagulant drugs increase the risk of unwanted bleeding, and regular monitoring is needed.... anticoagulant drugs

A group of drugs used to treat or prevent seizures. They are used mainly in the treatment of epilepsy but are also given to prevent seizures following serious head injury or some types of brain surgery. They may be needed to control seizures in children with a high fever (see convulsions, febrile).

Anticonvulsants may produce various side effects, including impaired memory, reduced concentration, poor coordination, and fatigue. If the side effects are severe, they can often be minimized by use of an alternative anticonvulsant.... anticonvulsant drugs

 Oedema. Hydrops. Not a disease but a condition. An abnormal accumulation of fluid in a body cavity or beneath the skin. Due to weakened walls of capillaries caused by circulating toxins obstructing the flow of blood or lymph. Gross oedema of nephrotic syndrome associated with low plasma protein level and high proteinuria.

Renal dropsy is worse in the early morning, with loose tissues under the eyes.

Treatment. When fluid rapidly collects it may have to be aspirated (drawn off) but before this stage is reached herbal diuretics and cardiac tonics have much to offer. In acute conditions, sweat glands should be stimulated by suitable diaphoretics to assist elimination of excess fluid through the skin. Attention to the bowels is important; a timely copious bowel action greatly assisting elimination. A well-known diuretic for dropsy is Juniper, 3 to 5 drops taken in honey 2 or 3 times daily.

Alternatives. Teas. (Simple infusions): Agrimony, Bearberry, Boldo, Boneset, Borage, Buchu, Celery seed, Clivers, Corn Silk, Dandelion leaves, Parsley leaves, Elderflowers, Bogbean, Heartsease, Lime flowers, Parsley Piert, Pellitory, Plantain, Sea Holly, Wild Carrot, Yarrow.

Drugs used to reduce or stop diarrhoea and to help regulate bowel action in people with a colostomy or ileostomy.

In most acute cases of diarrhoea, the only treatment recommended is oral rehydration therapy.

Antidiarrhoeal drugs include adsorbents, bulk-forming agents such as kaolin, and antimotility drugs (including the opioid drugs, morphine and codeine, and loperamide), which slow movement through the intestine.

None of these drugs are suitable for children.... antidiarrhoeal drugs

A group of drugs used to treat nausea and vomiting.

Antihistamine drugs and anticholinergic drugs reduce vomiting in motion sickness, vertigo, and Ménière’s disease.

The most powerful antiemetics are used to control nausea and vomiting associated with radiotherapy or anticancer drugs.

These drugs include serotonin antagonists such as ondansetron and nabilone.

Antiemetics are not normally used in the treatment of food poisoning because the body needs to rid itself of harmful substances.

Only certain antiemetics can be used to treat vomiting in early pregnancy because damage to the developing fetus may occur.

Many antiemetics cause drowsiness.... antiemetic drugs

Herbs should be harvested from unsprayed dust-free zones and spread out on racks or suitable fittings. Smaller batches may be hung in bunches. Rotting may set in if fresh herbs are left compressed in bags, baskets, etc. Never wash herbs before drying or place one above another. Turn or agitate daily. They should be dried in a well-ventilated room in the absence of excessive heat, sunlight or bright lights which may destroy the volatile oils of aromatic herbs. They should not be cut until thoroughly dried.

Only roots should be washed soon after lifting, and cut before drying into hardness. In a few cases drying of roots may be assisted by added heat. ... drying herbs

Alternative. Adopt Mecca position. Kneel down, place head on ground and tuck under. The spray will reach the maximum surface of action in the nasal cavity. ... nose drops drill

Drugs used to relieve pain. The 2 main types are nonopioid and opioid. Nonopioid analgesics, which include aspirin, paracetamol, and nonsteroidal anti-inflammatory drugs (NSAIDs), are useful in the treatment of mild to moderate pain (for example, headache or toothache). Combinationsof a weak opioid analgesic, such as codeine, with a nonopioid analgesic relieve more severe pain. Potent opioids such as morphine are used only when other preparations would be ineffective because they can produce tolerance and drug dependence.

Adverse effects are uncommon with paracetamol. Aspirin and NSAIDs may irritate the stomach lining and cause nausea, abdominal pain, and, rarely, a peptic ulcer. Nausea, drowsiness, constipation, and breathing difficulties may occur with opioid analgesics.... analgesic drugs

A group of drugs used to treat infections caused by fungi. Antifungal drugs are commonly used to treat different types of tinea, including athlete’s foot and scalp ringworm. They are also used for candidiasis (thrush) and rare fungal infections, such as cryptococcosis, that affect internal organs.

Antifungal preparations are available in various forms including tablets, injection, creams, and pessaries. Prolonged treatment of serious fungal infections can result in side effects that include liver or kidney damage.... antifungal drugs

Drugs that reduce inflammation. The main groups of these drugs are nonsteroidal antiinflammatory drugs and corticosteroid drugs. (See also analgesic drugs.)... anti-inflammatory drugs

Drugs used to treat malaria. One antimalarial drug, chloroquine, is also used to treat arthritis.... antimalarial drugs

Drugs that reduce the tendency of platelets to stick together to form blood clots when blood flow in the arteries is disrupted. This action reduces the risk of thromboembolism, which can cause potentially fatal disorders such as a myocardial infarction or stroke. Aspirin and dipyridamole are commonly used antiplatelet drugs. Others, such as ticlopidine, are used specifically to protect against clots forming in the coronary arteries of people with angina.... antiplatelet drugs

Drugs that are used to relieve persistent itching (pruritus).

Antipruritics may be applied as creams and emollients and may contain corticosteroid drugs, antihistamine drugs, or local anaesthetics.

Oral antihistamines may also be used to relieve itching.... antipruritic drugs

Natural or synthetic androgen hormones used as drugs; one of the most important is testosterone. These drugs are used in the treatment of male hypogonadism (underactivity of the testes) to stimulate the development of sexual characteristics.

Androgen drugs are occasionally used to treat certain types of breast cancer. They have been widely used by sportsmen wishing to increase muscle bulk and strength, a practice that is dangerous to health (see steroids, anabolic).

Adverse effects include fluid retention, weight gain, increased blood cholesterol, and, rarely, liver damage. When taken by women, the drugs can cause male characteristics, such as facial hair, to develop.

androgen hormones A group of hormones that stimulate the development of male sexual characteristics.

Androgens are produced by specialized cells in the testes in males and in the adrenal glands in both sexes. The ovaries secrete very small quantities of androgens until the menopause. The most active androgen is testosterone, which is produced in the testes. The production of androgens by the testes is controlled by certain pituitary hormones, called gonadotrophins. Adrenal androgens are controlled by ACTH, another pituitary hormone.

Androgens stimulate male secondary sexual characteristics at puberty, such as the growth of facial hair and deepening of the voice. They have an anabolic effect (they raise the rate of protein synthesis and lower the rate at which it is broken down). This increases muscle bulk and accelerates growth. At the end of puberty, androgens cause the long bones to stop growing. They stimulate sebum secretion, which, if excessive, causes acne. In early adult life, androgens promote male-pattern baldness.

Androgen deficiency may occur if the testes are diseased or if the pituitary gland fails to secrete gonadotrophins. Typical effects include decreased body and facial hair, a high-pitched voice, underdevelopment of the genitalia, and poor muscle development.

Overproduction of androgens may be the result of adrenal disorders (see adrenal tumours; adrenal hyperplasia, congenital), of testicular tumours (see testis, cancer of), or, rarely, of androgensecreting ovarian tumours (see ovary, cancer of).

In men, excess androgens accentuate male characteristics; in boys, they cause premature sexual development.

In women, excess androgens cause virilization, the development of masculine features such as an increase in body hair, deepening of the voice, clitoral enlargement, and amenorrhoea.... androgen drugs

A group of drugs used to treat infections caused by bacteria and to prevent bacterial infection in cases of immune system impairment.

Most of the commonly used antibiotic drugs belong to one of the following classes: penicillins, quinolones, aminoglycosides, cephalosporins, macrolides, and tetracyclines. Some antibiotics are effective against only certain types of bacteria; others, which are known as broad-spectrum antibiotics, are effective against a wide range.

Some bacteria develop resistance to a previously effective antibiotic drug. This is most likely to occur during long-term treatment. Some alternative antibiotics are available to treat bacteria that have become resistant to the more commonly prescribed drugs.

Most antibiotic drugs can cause nausea, diarrhoea, or a rash. Antibiotics may disturb the normal balance between certain types of bacteria and fungi in the body, leading to proliferation of the fungi that cause candidiasis (thrush). Some people experience a severe allergic reaction to the drugs, resulting in facial swelling, itching, or breathing difficulty.... antibiotic drugs

Drugs that are used to treat many forms of cancer. They are particularly useful in the treatment of lymphomas, leukaemias, breast cancer, cancer of the testis (see testis, cancer of), and prostate cancer and are often used together with surgery or radiotherapy.

Most anticancer drugs are cytotoxic (kill or damage rapidly dividing cells), but some act by slowing the growth of hormone-sensitive tumours. Anticancer drugs are often prescribed in combination to maximize their effects.

Treatment with cytotoxic drugs is often given by injection in short courses repeated at intervals. Some drugs cause nausea and vomiting and may result in hair loss and increased susceptibility to infection. Others, such as tamoxifen, which is used for breast cancer, are given continuously by mouth for months or years and cause few side effects.... anticancer drugs

Drugs that reduce fever. Examples of antipyretic drugs include paracetamol, aspirin, and other non-steroidal anti-inflammatory drugs.... antipyretic drugs

Drugs that are used to slow or halt the spread of viruses in people with HIV infection and AIDS. There are 3 main groups: reverse transcriptase inhibitors, protease inhibitors, and non-nucleoside reverse transcriptase inhibitors. Drugs from different groups are often used in combination. Antiretroviral drugs can have a range of side effects, including nausea, vomiting, diarrhoea, tiredness, and a range of effects on blood chemistry, particularly involving fats.... antiretroviral drugs

A group of drugs used to treat rheumatoid arthritis and types of arthritis that are caused by other autoimmune disorders such as systemic lupus erythematosus.

Antirheumatic drugs affect the disease process and may limit joint damage, unlike nonsteroidal anti-inflammatory drugs, which only relieve pain and stiffness.

The main antirheumatic drugs are corticosteroid drugs, immunosuppressant drugs, chloroquine, gold, penicillamine, and sulfasalazine.

Many of these drugs can have serious side effects, and treatment must be under specialist supervision.... antirheumatic drugs

A group of drugs that relax spasm in smooth muscle in the wall of the intestine or bladder. These drugs are used to treat irritable bowel syndrome and irritable bladder. Possible side effects include dry mouth, blurred vision, and difficulty in passing urine. (See also anticholinergic drugs.)... antispasmodic drugs

A group of drugs that block the effects of acetylcholine, a chemical released from nerve endings in the parasympathetic autonomic nervous system. Acetylcholine stimulates muscle contraction, increases secretions in the mouth and lungs, and slows the heartbeat.

Anticholinergic drugs are used in the treatment of irritable bowel syndrome, urinary incontinence, Parkinson’s disease, asthma, and bradycardia (abnormally slow heartbeat).

They are also used to dilate the pupil before eye examination or surgery.

Anticholinergic drugs are used as a premedication before general anaesthesia and to treat motion sickness.

They may cause dry mouth, blurred vision, urinary retention, and confusion.... anticholinergic drugs

Drugs that suppress or relieve a cough (see cough remedies).... antitussive drugs

Drugs used in the treatment of infection by viruses. No drugs have been developed that can eradicate viruses, and at present immunization is the most effective way of preventing serious viral infections.

However, antiviral drugs can reduce the severity of some viral infections (most notably herpes, influenza, viral hepatitis, and cytomegalovirus infections), particularly in people who have reduced immunity.

Advances have also been made in the treatment of infection (see antiretroviral drugs).... antiviral drugs

A group of sedative drugs that work by depressing activity within the brain. They include thiopental and phenobarbital. In the past, barbiturates were widely used as antianxiety drugs and sleeping drugs but have been largely replaced by benzodiazepine drugs and other nonbarbiturates. Barbiturates are now strictly controlled because they are habit-forming and widely abused. An overdose can be fatal, particularly in combination with alcohol, which dangerously increases the depressant effect on the brain (including suppression of the respiratory centre). However, phenobarbital is still commonly used as an anticonvulsant drug in the treatment of epilepsy. Thiopental is very short acting and is used to induce anaesthesia (see anaesthesia, general).... barbiturate drugs

A group of drugs given for short periods as sleeping drugs for insomnia and to control the symptoms of anxiety or stress (see tranquillizer drugs). Common benzodiazepines include diazepam, which is used as a tranquillizer, and nitrazepam, which is sometimes used for insomnia. Benzodiazepines are also used in the management of alcohol withdrawal and in the control of epilepsy.

Minor adverse effects of benzodiazepines include daytime drowsiness, dizziness, and forgetfulness. Unsteadiness and slowed reactions may also occur. Regular users may become psychologically and physically dependent; for this reason, the drugs are usually given for courses of 2–3 weeks or less. When the drugs are stopped suddenly, withdrawal symptoms, such as anxiety, restlessness, and nightmares may occur. Benzodiazepine drugs are sometimes abused for their sedative effect.... benzodiazepine drugs

A group of drugs, also known as beta-adrenergic blocking agents, prescribed principally to treat heart and circulatory disorders such as angina and hypertension. Beta-blockers block the effects of the sympathetic nervous system, which releases adrenaline (epinephrine) and noradrenaline (norepinephrine) at nerve endings that are known as beta receptors.

There are 2 types of beta receptor: beta 1 and beta 2. Beta 1 receptors are present in the heart and blood vessels, and beta 2 in the lungs. Some betablockers (such as acebutolol, atenolol, and metoprolol) are termed cardioselective and, because they act mostly on beta 1 receptors, are used mainly to treat heart disease such as angina, hypertension, and cardiac arrhythmia. The drugs are sometimes given after a myocardial infarction (heart attack) to reduce the likelihood of further damage to the heart muscle.

Other types of beta-blocker, such as oxprenolol, propranolol, and timolol, may be given to prevent migraine attacks by acting on blood vessels in the head; reduce the physical symptoms of anxiety; or control the symptoms of thyrotoxicosis. Beta-blocker drugs such as timolol are sometimes given in the

form of eye drops to treat glaucoma and work by lowering the fluid pressure in the eyeball.

Beta-blockers may reduce an individual’s capacity for strenuous exercise. The drugs may worsen the symptoms of asthma, bronchitis, or other forms of lung disease. They may also reduce the flow of blood to the limbs, causing cold hands and feet. In addition, sleep disturbance and depression can be side effects of beta-blockers.... beta-blocker drugs

See bisphosphonate drugs.... biphosphonate drugs

Drugs used to slow bone metabolism (for example in Paget’s disease) and to reduce the high calcium levels in the blood associated with destruction of bone by secondary cancer growths.

Bisphosphonates are also used in the prevention or treatment of osteoporosis.... bisphosphonate drugs

A large group of antibiotic drugs derived from the fungus

CEPHALOSPORIUM ACREMONIUM, which are effective against a wide range of infections.

Cephalosporins are used to treat ear, throat, and respiratory tract infections, and conditions, such as urinary tract infections and gonorrhoea, in which the causative bacteria are resistant to other types of antibiotics.

Occasionally, the drugs cause allergic reactions, such as rash, itching, and fever.

Rarely, anaphylactic shock occurs.

Other side effects include diarrhoea and blood disorders.... cephalosporin drugs

A group of drugs that widen the bronchioles (small airways in the lungs) to increase air flow and improve breathing, especially in the treatment of asthma and chronic obstructive pulmonary disease (see pulmonary disease, chronic obstructive). There are 3 main types of bronchodilator: sympathomimetic drugs (such as salbutamol), anticholinergic drugs, and xanthine drugs (such as aminophylline). Sympathomimetic drugs are used primarily for the rapid relief of breathing difficulty. Anticholinergic and xanthine drugs are more often used for the long-term prevention of attacks of breathing difficulty. Drugs can be given by inhaler, in tablet form, or, in severe cases, by nebulizer or injection.

The main side effects of sympathomimetics are palpitations and trembling.

Anticholinergics may cause dry mouth, blurred vision, and, rarely, difficulty in passing urine.

Xanthines may cause headaches, nausea and palpitations.... bronchodilator drugs

A preparation containing more than one active substance.... combination drug

A group of drugs that are similar to the corticosteroid hormones produced by the adrenal glands. Corticosteroids are used as hormone replacement therapy in Addison’s disease and when the adrenal glands or pituitary gland have been destroyed or removed. They are also used to treat inflammatory intestinal disorders such as ulcerative colitis and Crohn’s disease and as an urgent treatment for inflammation in the artery supplying the retina in temporal arteritis. Other uses include treatment of autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis, and treatment of asthma, eczema, and allergic rhinitis. Corticosteroid drugs are also used to prevent organ rejection after transplant surgery and in the treatment of some types of cancer, such as a lymphoma or leukaemia. Corticosteroid injections may relieve pain in disorders such as tennis elbow and arthritis.

Side effects are uncommon when corticosteroids are given as a cream or by inhaler, but tablets taken in high doses for long periods may cause oedema, hypertension, diabetes mellitus, peptic ulcer, Cushing’s syndrome, inhibited growth in children, and, in rare cases, cataract or psychosis. High doses also impair the body’s immune system. Long-term treatment suppresses production of corticosteroid hormones by the adrenal glands, and sudden withdrawal may lead to adrenal failure.... corticosteroid drugs

A group of non-steroidal anti-inflammatory drugs (NSAIDs) that cause less stomach irritation as a side effect than other NSAIDs. Examples of -2 inhibitors include celecoxib and rofecoxib.... cox-2 inhibitor drugs

Drugs that are used to relieve nasal congestion commonly in people with upper respiratory tract infections.

They work by narrowing blood vessels in the membranes lining the nose.

This action reduces swelling, inflammation, and the amount of mucus produced by the lining.

Common drugs include ephedrine, oxymetazoline, and phenylephrine.

Small amounts of these drugs are present in many over-thecounter cold remedies.

Taken by mouth, decongestant drugs may cause tremor and palpitations.

Adverse effects are unlikely with nose drops, but if taken for several days they become ineffective and symptoms may then recur or worsen despite continued treatment.... decongestant drugs

A group of drugs that are extracted from plants belonging to the foxglove family.

They are used to treat heart conditions, most commonly atrial fibrillation.

Those most frequently used are digitoxin and digoxin.... digitalis drugs

An appliance inserted into a body cavity or wound to release air or to permit drainage.

Drains range from simple soft rubber tubes that pass from a body cavity into a dressing to wide-bore tubes that connect to a collection bag or bottle.

Suction drains are thin tubes with many small holes to help collect fluid or air, which is drawn into a vacuum bottle.... drain, surgical

The interpretation of a person’s dreams as part of psychoanalysis or psychotherapy.

First developed by Sigmund Freud, it is based on the idea that repressed feelings and thoughts are revealed, in a disguised manner, in dreams.... dream analysis

Mental activity that takes place during sleep. It is thought to occur only during periods of (rapid eye movement) sleep, which last for about 20 minutes and occur 4–5 times a night. Compared to other phases, the phase of sleep is active. Blood flow and brain temperature increase, and there are sudden changes in heart-rate and blood pressure.

Dreams usually closely mirror the day’s preoccupations.

Dreaming can be seen as a process in which the mental impressions, feelings, and ideas are sorted out.

People roused during sleep report especially vivid dreams.... dreaming

An uncommon disorder, also known as postinfarction syndrome, that may occur after a myocardial infarction (heart attack) or heart surgery.

It is characterized by fever, chest pain, pericarditis, and pleurisy.

Treatment is with aspirin or, in severe cases, with corticosteroid drugs.... dressler’s syndrome

Drugs that help remove excess water from the body by increasing the amount lost as urine. They are used in the treatment of various disorders, which include severe premenstrual syndrome, hypertension, heart failure, the eye condition glaucoma, nephrotic syndrome, and cirrhosis of the liver.

Types of diuretic drug differ markedly in their speed and mode of action. Thiazide diuretics cause a moderate increase in urine production. Loop diuretics are fast-acting, powerful drugs. They are often used as an emergency treatment for heart failure. Potassium-sparing diuretics are used along with thiazide and loop diuretics, both of which may cause the body to lose too much potassium. Carbonic anhydrase inhibitors block the action of the enzyme carbonic anhydrase, which affects the amount of bicarbonate ions in the blood; these drugs increase urine output moderately but are effective only for short periods of time. Osmotic diuretics are used to maintain urine output following serious injury or major surgery.

Diuretic drugs may cause chemical imbalances in the blood.

Hypokalaemia (low blood levels of potassium) is usually treated with potassium supplements or potassium-sparing diuretic drugs.

A diet rich in potassium may be helpful.

Some diuretics raise the blood level of uric acid, increasing the risk of gout.

Certain diuretics increase the blood glucose level, which can cause or worsen diabetes mellitus.... diuretic drugs

Involuntary leakage of urine (see incontinence, urinary) or of saliva from the mouth (also known as drooling).

Dribbling of saliva is normal in infants.

In adults, it may be due to poorly fitting dentures or may be the result of facial paralysis, dementia, or another disorder of the nervous system, most commonly Parkinson’s disease.

Dribbling of saliva may also be caused by obstruction to swallowing.... dribbling

A form of drowning in which no fluid enters the lungs.

Some fatal drowning cases are “dry”.

Victims have a particularly strong laryngeal reflex, which diverts water into the stomach but at the same time impairs breathing.... drowning, dry

A state of consciousness between full wakefulness and sleep or unconsciousness. Drowsiness is medically significant if a person fails to awaken after being shaken, pinched, and shouted at, or wakes but relapses into drowsiness.

Abnormal drowsiness may be the result of a head injury, high fever, meningitis, uraemia (excess urea in the blood due to kidney failure), or liver failure.

Alcohol or drugs may also produce this effect.

In a person with diabetes mellitus, drowsiness may be due to hypoglycaemia or to hyperglycaemia.

Abnormal drowsiness should be treated as a medical emergency.... drowsiness

Use of a drug for a purpose other than that for which it is normally prescribed or recommended. Commonly abused drugs include stimulant drugs, such as cocaine and amfetamine drugs; central nervous system depressants, such as alcohol and barbiturate drugs; hallucinogenic drugs, such as LSD; and narcotics (see opioid drugs), such as heroin. Some drugs are abused in order to improve performance in sports (see sports, drugs and; steroids, anabolic).

Problems resulting from drug abuse may arise from the adverse effects of the drug, accidents that occur during intoxication, or from the habit-forming potential of many drugs, which may lead to drug dependence.... drug abuse

The effect of a drug when it is taken in combination with other drugs or with substances such as alcohol.... drug interaction

The taking of an excessive amount of a drug, which may cause toxic effects (see drug poisoning).... drug overdose

The harmful effects on the body as a result of an excessive dose of a drug. Accidental poisoning is most common in young children. In adults, it usually occurs in elderly or confused people who are unsure about their treatment and dosage requirements. Accidental poisoning may also occur during drug abuse. Deliberate self-poisoning is usually a cry for help (see suicide; suicide, attempted). The drugs that are most commonly taken in overdose include benzodiazepine drugs and antidepressant drugs. Anyone who has taken a drug overdose and any child who has swallowed tablets that belong to someone else should seek immediate medical advice. It is important to identify the drugs that have been taken. Treatment in hospital may involve washing out the stomach (see lavage, gastric). Charcoal may be given by mouth to reduce the absorption of the drug from the intestine into the bloodstream. To eliminate the drug, urine production may be increased by an intravenous infusion. Antidotes are available only for specific drugs. Such antidotes include naloxone (for morphine) and methionine (for paracetamol).

Drug poisoning may cause drowsiness and breathing difficulty, irregular heartbeat, and, rarely, cardiac arrest, fits, and kidney and liver damage.

Antiarrhythmic drugs are given to treat heartbeat irregularity.

Fits are treated with anticonvulsants.

Blood tests to monitor liver function and careful monitoring of urine output are carried out if the drug is known to damage the liver or kidneys.... drug poisoning

See ptosis.... eyelid, drooping

A group of hormonal or hormone-related drugs used to treat some types of infertility.

In women, fertility drugs may be given when abnormal hormone production by the pituitary gland or ovaries disrupts ovulation or causes mucus around the cervix to become so thick that sperm cannot penetrate it. In men, fertility drugs are less effective, but they may be used when abnormal hormone production by the pituitary gland or testes interferes with sperm production. (See also clomifene; gonadotrophin hormones; testosterone.)... fertility drugs

A condition in which the foot cannot be raised properly and hangs limp from the ankle. Neuritis affecting the nerves that supply muscles that move the foot is a common cause and may be due to diabetes mellitus, multiple sclerosis, or a neuropathy. Weakness in the foot muscles can also result from pressure on a nerve (due to a disc prolapse or a tumour) as it leaves the spinal cord. Treatment is of the underlying cause, but in many people the weakness persists. A lightweight plastic caliper splint can be used to keep the foot in place when walking.... foot-drop

A group of drugs used to treat bleeding disorders and to control bleeding. Haemostatic preparations that help blood clotting are given to people who have deficiencies of natural clotting factors. For example, factor VIII is used to treat haemophilia. Drugs that prevent the breakdown of fibrin in clots, such as tranexamic acid, can also improve haemostasis.... haemostatic drugs

A group of drugs that reduce the activity of the immune system. They include azathioprine, ciclosporin, cyclophosphamide, methotrexate, and prednisolone. Immunosuppressants are given to prevent rejection after transplant surgery and to slow the progress of autoimmune disorders such as rheumatoid arthritis and systemic lupus erythematosus.

The drugs work by suppressing the production and activity of white blood cells called lymphocytes. Side effects vary, but all the drugs increase the risk of infection and of the development of certain cancers.... immunosuppressant drugs

Drugs that loosen and remove the tough outer layer of skin.

Keratolytic drugs, which include urea and salicylic acid preparations, are used to treat skin and scalp disorders, such as warts, acne, dandruff, and psoriasis.... keratolytic drugs

A group of drugs used to treat constipation.

There are various types.

Bulk-forming laxatives increase the volume and softness of faeces and make them easier to pass.

Stimulant laxatives stimulate the intestinal wall to contract and speed up the elimination of faeces.

Lubricant laxatives soften and facilitate the passage of faeces.

Osmotic laxatives increase the water content and volume of the faeces.

If used in excess, laxative drugs may cause diarrhoea, abdominal cramps, and flatulence, and may impair normal bowel function.... laxative drugs

Common macrolides include azithromycin and erythromycin.... macrolide drugs

Drugs used in the treatment of glaucoma to reduce pressure in the eye. Used topically, miotic drugs cause the pupil to contract, which opens up the drainage channels and drains fluid from the front of the eye. Side effects include headache, particularly over the eye, and blurred vision. Common miotics include carbachol and pilocarpine. (See also mydriatic drugs.)... miotic drugs

Drugs that make sputum (phlegm) less sticky and easier to cough up. An example is acetylcysteine.... mucolytic drugs

A group of drugs used to relieve muscle spasm and spasticity. Muscle-relaxant drugs are used mainly in the treatment of nervoussystem disorders such as multiple sclerosis and painful muscular conditions such as torticollis. They are occasionally used to relieve muscle rigidity caused by injury. Some types are used to cause temporary paralysis during surgery under general anaesthesia.Except for dantrolene, muscle-relaxant drugs partly block nerve signals that stimulate muscle contraction. Dantrolene interferes with the chemical activity in muscle cells needed for contraction.

The drugs may cause muscle weakness and drowsiness. In rare cases, dantrolene causes liver damage.... muscle-relaxant drugs

A group of drugs used to treat uveitis and to dilate the pupil during examination of the inside of the eye and for surgery. Mydriatics work by relaxing the circular muscles of the iris, causing the pupil to dilate. Common mydriatic drugs include tropicamide, cyclopentolate, homatropine, and phenylephrine. (See also cycloplegia; miotic drugs.)... mydriatic drugs

See opioid analgesic drugs.... narcotic drugs

Possible side effects of nitrate drugs include headache, flushing, and dizziness. Tolerance (the need for greater amounts of a drug for it to have the same effect) may develop when the drug is taken regularly.... nitrate drugs

Drugs that have been developed to treat rare conditions but are not manufactured generally.... orphan drugs

A group of drugs, also known as NSAIDs that produce analgesia (pain relief) and reduce inflammation in joints and soft tissues such as muscles and ligaments.

Nonsteroidal anti-inflammatory drugs are widely used to relieve symptoms caused by types of arthritis, such as rheumatoid arthritis, osteoarthritis, and gout. They do not cure or halt the progress of disease. NSAIDs are also used in the treatment of back pain, menstrual pain, headaches, pain after minor surgery, and soft tissue injuries.

The drugs reduce pain and inflammation by blocking the production of prostaglandins (chemicals that cause inflammation and trigger transmission of pain signals to the brain).

NSAIDs may cause a wide range of side effects, the most important of which are nausea, indigestion, bleeding from the stomach, and, sometimes, peptic ulcer.... nonsteroidal anti-inflammatory drugs

A group of synthetically produced drugs that are used in oral contraceptives and to supplement or replace the body’s own oestrogen hormones.

Oestrogen drugs are often used together with progestogen drugs.

Oestrogens suppress the production of gonadotrophin hormones, which stimulate cell activity in the ovaries. High doses are used in postcoital contraception to prevent conception (see contraception, emergency). They are also used to treat, or sometimes prevent, menopausal symptoms and disorders. Oestrogens may be used to treat certain forms of infertility, female hypogonadism, abnormal menstrual bleeding, prostatic cancer (see prostate, cancer of), and certain types of breast cancer.

Oestrogens may cause breast tenderness and enlargement, bloating, weight gain, nausea, reduced sex drive, depression, migraine, and bleeding between periods. Side effects often subside after 2 or 3 months. The drugs can increase the risk of abnormal blood clotting and susceptibility to high blood pressure (see hypertension). Oestrogen drugs should not be taken in pregnancy as they may adversely affect the fetus.... oestrogen drugs

A group of antibiotic drugs.

Natural penicillins are derived from the mould PENICILLIUM; others are synthetic preparations.

The fluid may cause a cough, hoarseness, or the feeling of a foreign body.

The usual cause is rhinitis.... postnasal drip

Certain drugs taken during pregnancy may pass to the fetus through the placenta or interfere with fetal development. This may lead to birth defects. Although relatively few drugs have been proved to cause harm to a developing baby, no drug should be considered completely safe, especially during early pregnancy. For this reason, pregnant women should seek advice from their doctor or pharmacist before taking any drug, including over-thecounter preparations.

Problems may also be caused in a developing baby if a pregnant woman drinks alcohol, smokes (see tobaccosmoking), or takes drugs of abuse. The babies of women who use heroin during pregnancy tend to have a low birthweight and a higher death rate than normal during the first few weeks of life. Babies of women who abuse drugs intravenously are at high risk of HIV infection.... pregnancy, drugs in

A group of drugs similar to progesterone hormone. The drugs are used in oral contraceptives, are prescribed to treat menstrual problems (see menstruation, disorders of), and are included in hormone replacement therapy (HRT). Progestogen drugs are also used to treat premenstrual syndrome, endometriosis, and hypogonadism, and are sometimes used as anticancer drugs. Adverse effects include weight gain, oedema, headache, dizziness, rash, irregular periods, breast tenderness, and ovarian cysts.... progestogen drugs

Drugs containing chemicals called psoralens, which occur in some plants and are present in some perfumes.

When absorbed into the skin, psoralens react with ultraviolet light to cause skin darkening or inflammation.

Psoralen drugs may be used in conjunction with ultraviolet light (a combination called PUVA) to treat psoriasis and vitiligo.

Overexposure to ultraviolet light during treatment, or to too high a dose of a psoralen drug, may cause redness and blistering of the skin.

Psoralens in perfumes may cause photosensitivity.... psoralen drugs

Four main types of drug are abused by athletes to enhance physical or mental condition.

Stimulants such as amfetamines can prevent fatigue and increase confidence.

Three types of hormone drugs may be abused: anabolic steroids (see steroids, anabolic) to speed muscle recovery after exercise; erythropoietin to boost the haemoglobin content of the blood, which may increase stamina; and growth hormone to stimulate muscle growth.

Analgesic drugs may be used to mask the pain of an injury.

Betablockers are taken to reduce tremor in sports that require a steady hand.

Aside from the health risks associated with abuse of these drugs, their use is prohibited in many competitive sports.... sport, drugs and

If taken with milk, tetracyclines are not absorbed effectively into the intestines.

Possible side effects include nausea, vomiting, diarrhoea, worsening of kidney disorders, rash, and itching.

Tetracyclines may discolour developing teeth and are therefore not usually prescribed for children under age 12 or pregnant women.... tetracycline drugs

Sometimes called fibrinolytic drugs, this group of drugs is used to treat thrombosis, embolism, and myocardial infarction.

Thrombolytic drugs act within blood vessels to dissolve clots.

Possible adverse effects include abnormal bleeding and an allergic reaction.... thrombolytic drugs

Drugs that have a sedative effect. Tranquillizers are divided into 2 types: major tranquillizers (see antipsychotic drugs) and minor tranquillizers (see antianxiety drugs).... tranquillizer drugs

A group of drugs that widen blood vessels.

Vasodilator drugs include ACE inhibitors, alphablockers, calcium channel blockers, nitrate drugs, and sympatholytic drugs.

They are used to treat disorders in which abnormal narrowing of blood vessels reduces blood flow through tissues, impairing the supply of oxygen.

Such disorders include angina pectoris and peripheral vascular disease.

Vasodilators are also used to treat hypertension and heart failure.

All vasodilator drugs may cause flushing, headaches, dizziness, fainting, and swollen ankles.... vasodilator drugs

any drug that damages or destroys cells: usually refers to those drugs used to treat various types of cancer. There are various classes of cytotoxic drugs, including *alkylating agents (e.g. *chlorambucil, *cyclophosphamide, *melphalan), *antimetabolites (e.g. *fluorouracil, *methotrexate, *mercaptopurine), *anthracycline antibiotics (e.g. *doxorubicin, *daunorubicin, *dactinomycin), *vinca alkaloids, and platinum compounds (e.g. *carboplatin, *cisplatin). Other cytotoxic drugs include *taxanes and *topoisomerase inhibitors, and some *monoclonal antibodies (e.g. *bevacizumab, *trastuzumab) have cytotoxic activity. All these drugs offer successful treatment in some conditions and help reduce symptoms and prolong life in others. Cytotoxic drugs destroy cancer cells by interfering with cell division, but they also affect normal cells, particularly in bone marrow (causing *myelosuppression), hair follicles (causing hair loss), the stomach lining (resulting in severe nausea and vomiting), mouth (causing soreness), and fetal tissue (they should not be taken during the later stages of pregnancy). Dosage must therefore be carefully controlled. See also chemotherapy.... cytotoxic drug
