Calcium channel blockers are drugs that block the entry of calcium into the muscle cells of the heart and arteries. Calcium channel blockers CCBs are a class of drugs that dilate the arteries and are used for treating high blood pressure abnormally rapid heart rhythms pulmonary hypertension Raynauds syndrome cardiomyopathy and subarachnoid hemorrhage.

Calcium Channel Blockers Flashcards Quizlet

The entry of calcium is critical for the conduction of the electrical signal that passes from muscle cell to muscle cell of.

Calcium channel blockers definition. A drug that blocks the entry of calcium into the muscle cells of the heart and the arteries. Calcium-channel blockers sometimes called calcium antagonists are a group of medicines that affect the way calcium passes into certain muscle cells. Since they are inducers of vascular and other smooth muscle relaxation they are used in the drug therapy of hypertension and cerebrovascular spasms as myocardial protective agents and in the.

Calcium channel blocker definition is - any of a class of drugs such as verapamil that prevent or slow the influx of calcium ions into smooth muscle cells and are used especially to treat some forms of angina pectoris and some cardiac arrhythmias. Calcium Channel Blockers A class of drugs that act by selective inhibition of calcium influx through cell membranes or on the release and binding of calcium in intracellular pools. In coronary and peripheral arterial smooth muscle and the heart inhibition of Ca2 entry blunts the ability.

Definition Calcium channel blockers are medicines that slow the movement of calcium into the cells of the heart and blood vessels. A drug that blocks the entry of calcium into the muscle cells of the heart and the arteries. 40 rows Calcium channel blocking agents restrict the amount of calcium entering cardiac.

This leads to a greater predisposition to epileptic episodes. It is the entry of calcium into these cells that causes the heart to contract and arteries to narrow. Calcium channel blocker.

Any of a class of drugs that inhibit movement of calcium ions across a cell membrane used in the treatment of cardiovascular disorders. The calcium-channel blockers represent a group of organic chemical structures that share the ability to inhibit Ca2 entry into excitable cells. Definition of Calcium channel blocker Calcium channel blocker.

Calcium channel blockers reduce the neuronal calcium conductance and reduce the likelihood of experiencing epileptic attacks. T-type calcium channel blockers are used to treat epilepsy. Any of a class of drugs that inhibit the movement of calcium ions across the cell membranes of cardiac and smooth muscle and are used to treat cardiovascular disorders.

Calcium channel blocker n. Definition A pharmaceutical agent that inhibits the movement of calcium across through calcium channels in the cell membrane preventing or decreasing the amount of calcium able to enter the cell. Used in the treatment of Prinzmetals angina chronic stable angina and cardiac arrhythmias.

Calcium channel blockers lower blood pressure and treat other conditions such as chest pain and an irregular heartbeat. Increased calcium conductance in the neurons leads to increased depolarization and excitability. This in turn relaxes blood vessels increases the supply of oxygen-rich blood to the heart and reduces the hearts workload.

These drugs are used for their chronotropic antihypertensive and. It is the entry of calcium into these cells that causes the heart to contract and arteries to narrow. Calcium channel blocker calcium channel blocking agent a drug such as nifedipine diltiazem or verapamil that selectively blocks the influx of calcium ions through a calcium channel of cardiac muscle and smooth muscle cells.

By blocking the entry of calcium calcium channel blocker CCBs decrease the contraction of the heart and dilate widen the arteries. This in turn relaxes blood vessels increases the supply of oxygen-rich blood to the heart and reduces the hearts workload. Definition Calcium channel blockers are medicines that slow the movement of calcium into the cells of the heart and blood vessels.

American Heritage Dictionary of the English Language Fifth Edition. By Mayo Clinic Staff Calcium channel blockers lower your blood pressure by preventing calcium from entering the cells of your heart and arteries. They are used to treat various conditions including high blood pressure angina Raynauds phenomenon and some abnormal heart rhythms arrhythmias.

Calcium causes the heart and arteries to contract more strongly.
