Calcium-Channel Blocker
Calcium-Channel Blocker A drug that reduces spasm of the blood vessels, lowers blood pressure, and controls angina; acts by selectively blocking the uptake of calcium by the cells.
RELATED TERMS--------------------------------------
Spasm
A condition in which a muscle or group of muscles involuntarily contract.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Angina
A recurring pain or discomfort in the chest that happens when some part of the heart does not receive enough blood. It is a common symptom of coronary heart disease, which occurs when vessels that carry blood to the heart become narrowed and blocked due to atherosclerosis. Angina feels like a pressing or squeezing pain, usually in the chest under the breast bone, but sometimes in the shoulders, arms, neck, jaws, or back. Angina is usually is brought on by exertion, and relieved within a few minutes by resting or by taking prescribed angina medicine. Commonly called chest pain, heart pain or angina pectoris.
Blocking
A sudden obstruction or interruption in spontaneous flow of thinking or speaking, perceived as an absence or deprivation of thought.
Calcium
Chemical element needed for healthy teeth, bones and nerves

Calcific bursitis
A bursa is a thin fluid-filled sac that reduces friction forces between tissues of the body. Chronic (repeated of long-standing) inflammation of the bursa (bursitis) can lead to calcification of the bursa. This is referred to as "calcific bursitis." The calcium deposition (calcification) can occur as long as the inflammation is present.
Calcification
Formation of calcific (chalky) material in tissue.
Calcification, nonarteriosclerotic cerebral
Is a genetic neurological disorder characterized by abnormal deposits of calcium in certain of areas of the brain (including the basal ganglia and the cerebral cortex). Symptoms may include motor function deterioration, dementia, mental retardation, spastic paralysis, dysarthria (poorly articulated speech), spasticity (stiffness of the limbs), ocular (eye) problems, and athetosis (involuntary, writhing movements).
Calcified granuloma
A calcified granuloma is a granuloma containing calcium deposits. Since it usually takes some time for calcium to be deposited in a granuloma, it is generally assumed that a calcified granuloma is an old granuloma.

Calcimimetic
A drug in a class of orally active, small molecules that decrease the secretion of parathyroid hormone (PTH) by activating calcium receptors. The secretion of PTH is normally regulated by the calcium-sensing receptor. Calcimimetic agents increase the sensitivity of this receptor to calcium, which inhibits the release of parathyroid hormone and lowers parathyroid hormone levels within a few hours.
Calcinosis
An abnormal deposit of calcium salts in body tissues, as is seen in some forms of disease.

Calcium chloride 10 per cent in plastic container is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): calcium chloride.
Calcium deficiency
A low level of calcium in the blood (hypocalcemia) which can make the nervous system highly irritable causing tetany (spasms of the hands and feet, muscle cramps, abdominal cramps, and overly active reflexes). Chronic calcium deficiency contributes to poor mineralization of bones, soft bones (osteomalacia) and osteoporosis and, in children, rickets and impaired growth.

Calculi
Stones or solid lumps such as gallstones.
Calculi, renal
Kidney stones, by another name. A common cause of blood in the urine and pain in the abdomen, flank, or groin. Occurs in 1 in 20 people at some time in their life. Development of the stones is related to decreased urine volume or increased excretion of stone-forming components such as calcium, oxalate, urate, cystine, xanthine, and phosphate. The stones form in the urine collecting area (the pelvis) of the kidney and may range in size from tiny to staghorn stones the size of the renal pelvis itself . The pain is usually of sudden onset, very severe and colicky (intermittent), not improved by changes in position, radiating from the back, down the flank, and into the groin. Nausea and vomiting are common. Predisposing factors may include recent reduction in fluid intake, increased exercise with dehydration, medications that cause hyperuricemia (high uric acid) and a history of gout. Treatment includes relief of pain, hydration and, if there is concurrent urinary infection, antibiotics. The majority of stones pass spontaneously within 48 hours. However, some stones may not. There are several factors which influence the ability to pass a stone. These include the size of the person, prior stone passage, prostate enlargement, pregnancy, and the size of the stone. A 4 mm stone has an 80% chance of passage while a 5 mm stone has a 20% chance. If a stone does not pass, urologic intervention may be needed. The process of stone formation is also called nephrolithiasis or urolithiasis.
Calculus
Hard residue, commonly known as "tarter," that forms on teeth due to inadequate
plaque control, often stained yellow or brown.
Calculus, renal
A stone in the kidney (or lower down in the urinary tract). Also called a kidney stone. The stones themselves are called renal caluli.

Carbon Monoxide
A gas found in cigarette smoke; damages artery walls and reduces the ability of blood to carry oxygen, increasing the risk of coronary artery disease.
Cardiac Arrest
When the heart stops beating suddenly and respiration (breathing) and other body functions stop as a result.
Cardiac Auscultation
The use of a stethoscope to listen to the sounds the heart makes as it contracts and relaxes. Cardiac auscultation can be used to evaluate the heart rate, rhythm, and flow through the valves.
Cardiac Catheterization
An invasive imaging procedure that involves inserting a catheter into a blood vessel in the arm or leg, and guiding it to your heart with the aid of a special x-ray machine. Contrast dye is injected through the catheter so that x-ray movies of your valves, coronary arteries and heart chambers are taken. Cardiac catheterization is also called coronary angiography.
