Capsule

A term used in several senses in medicine. It is applied to a soluble case, usually of gelatine, for enclosing small doses of unpleasant medicine.

Enteric-coated capsules, which have been largely superseded by enteric-coated tablets, are capsules treated in such a manner that the ingredients do not come in contact with the acid stomach contents but are only released when the capsule disintegrates in the alkaline contents of the intestine.

The term is also applied to the ?brous or membranous envelope of various organs, as of the spleen, liver or kidney. Additionally, it is applied to the ligamentous bag surrounding various joints and attached by its edge to the bones on either side.... capsule

Captopril

An ACE-inhibitor drug introduced for the treatment of patients with severe HYPERTENSION. It acts by lowering the concentration in the blood of angiotensin II which is one of the factors responsible for high blood pressure. (See ANGIOTENSIN; RENIN.)... captopril

Capd

Capillaries

The minute vessels which join the ends of the arteries to venules, the tiny commencement of veins. Their walls consist of a single layer of ?ne, ?at, transparent cells, bound together at the edges, and the vessels form a meshwork all through the tissues of the body, bathing the latter in blood with only the thin capillary wall interposed, through which gases and ?uids readily pass. These vessels are less than 0·025 mm in width.... capillaries

Caput Succedaneum

Usually shortened by obstetricians to ‘caput’, this is the temporary swelling which is sometimes found on the head of the newborn infant. It is due to OEDEMA in and around the scalp, caused by pressure on the head as the child is born. It is of no signi?cance and quickly disappears spontaneously.... caput succedaneum

Vital Capacity

The amount of air that can be forcibly exhaled from the lungs after a deep inspiration. (See RESPIRATION.)... vital capacity

Capillary

Any of the vessels that carry blood between the smallest arteries, or arterioles, and the smallest veins, or venules (see circulatory system). Capillaries form a fine network throughout the body’s organs and tissues. Their thin walls are permeable and allow blood and cells to exchange constituents such as oxygen, glucose, carbon dioxide, and water (see respiration). Capillaries open and close to blood flow according to the requirements of different organs. The opening and closing of skin capillaries helps to regulate temperature.

A direct blow to the body may rupture the thin capillary walls, causing bleeding under the surface of the skin, which in turn causes swelling and bruising. Increasing age, high doses of corticosteroid drugs, and scurvy (vitamin C deficiency) make capillaries more fragile; a tendency to purpura (small areas of bleeding under the skin) may develop.... capillary

Caplllary

The smallest blood or lymph vessel, formed of single layers of interconnected endothelial cells, sometimes with loosely attached connective tissue basement cells for added support. Capillaries allow the transport across their membranes and between their crevices of diffusible nutrients and waste products. Blood capillaries expand and contract, depending upon how much blood is needed in a given tissue and how much is piped into them by the small feeder arteries upstream. They further maintain a strong repelling charge that keeps blood proteins and red blood cells pushed into the center of the flow. Lymph capillaries have many open crypts, allowing free absorption of interstitial fluid forced out of the blood; these capillaries tend to maintain a charge that attracts bits of cellular garbage too large to return through the membranes of exiting venous capillaries.... caplllary

Capsaicin stimulates the circulation and alters temperature regulation; topically desensitizes nerve endings and acts as a local analgesic.

Capsaicin produces a protective effect in rat lung and liver by strengthening the pulmonary antioxidant enzyme defence system. Acute capsaicin treatment causes release of substance desensitization of the respiratory tract mucosa to a variety of lung irritants.

Red pepper or an equivalent amount of capsaicin, when fed along with cholesterol-containing diets to female albino rats, prevented significantly the rise of liver cholesterol levels.

Vitamin P has been isolated from the chillies. Vitamin C gradually increases during maturation and reaches maximum at the semi-ripe or pink coloured stage and decreases thereafter.

Capsicum

See: CAYENNE.

CAPSULES. A convenient vehicle for administration of powders, seeds, oils, balsams, Castor oil, Garlic, Rose Hip, etc, having the advantage to mask nasty tasting or smelly medicines. Ideal for regulating dosage for children. Swallowed, they soon reach the stomach where their contents are slowly released. Gelatin capsules are of animal origin but cellulose non-animal materials are available. Their use extends also to gynaecological and rectal problems, inserted into the vagina or anus.

Standard sizes range from size 5 to 000. Size 00 is most popular in European pharmacy. See: POWDERS.

To fill empty capsules, take apart the two sections, ‘dab’ open end into powder on a flat surface; fill to capacity and affix unfilled half-shell. Manufacturers use a special filling machine for this purpose.

Patients should remain standing for at least 90 seconds after taking capsules, and followed up with sips of water. Swallowing failure is possible when capsules are taken in the recumbent position when they may adhere to the oesophageal membrane delaying disintegration time.

Capillary Refill Time

a quickly performed test to assess the adequacy of circulation in an individual with poor cardiac output. An area of skin is pressed firmly by (say) a fingertip until it loses its colour; the number of seconds for the area to return to its original colour indicates capillary refill time. Normal capillary refill takes around 2 seconds. Slow capillary refill may occur globally in an individual with poor circulation or in a small area (e.g. a toe) in which local circulation is compromised (due, for example, to peripheral vascular disease). This test may not be very useful in people with dark skin.... capillary refill time

Capacity

n. the state of being able to make decisions about one’s medical care, i.e. to consent to or to refuse treatment.

Mental Capacity Act 2005

legislation for England and Wales, which came into force in October 2007, to govern the treatment of people who lack *capacity to make decisions. It gives legal force to the importance of *autonomy in health care and to *advance directives, decisions, or statements. It also provides statutory legislation for medical and social decision-makers to act in the patient’s best interests should he or she lose capacity (see Independent Mental Capacity Advocate). It allows proportionate force to implement decisions made in a patient’s best interests.
