calcium channel
1Calcium channel — A Calcium channel is an ion channel which displays selective permeabiltiy to calcium ions. It is sometimes synonymous as voltage dependent calcium channel, [DorlandsDict|two/000019812|calcium channel] although there are also ligand gated calcium… …
2calcium channel blocker — n any of a class of drugs (as verapamil) that prevent or slow the influx of calcium ions into smooth muscle cells esp. of the heart and that are used esp. to treat some forms of angina pectoris and some cardiac arrhythmias called also calcium… …
3calcium channel blocker — n. any of a class of drugs, including nifedipine, diltiazem, and verapamil, that relax vascular and other smooth muscle tissue by preventing calcium ions from entering their cells, used to treat headaches, high blood pressure, angina pectoris,… …
4calcium channel blocker — n. any of a class of drugs, including nifedipine, diltiazem, and verapamil, that relax vascular and other smooth muscle tissue by preventing calcium ions from entering their cells, used to treat headaches, high blood pressure, angina pectoris,… …
5calcium-channel blocker — calcium antagonist a drug that inhibits the influx of calcium ions into cardiac and smooth muscle cells; it therefore reduces the strength of heart muscle contraction, reduces conduction of impulses in the heart, and causes vasodilatation.… …
6Calcium channel blocker — A calcium channel blocker (CCB) is a chemical that disrupts the movement of calcium (Ca2+) through calcium channels.[1] CCB drugs devised to target neurons are used as antiepileptics. However, the most widespread clinical usage of calcium channel …
7calcium channel — Membrane channel that is specific for calcium. Probably the best characterized is the voltage gated channel of the sarcoplasmic reticulum which is ryanodine sensitive. See voltage sensitive calcium channels …
8calcium channel — a voltage gated channel, very permeable to calcium ions and slightly permeable to sodium ions, that upon activation by membrane depolarization allows calcium to flow into the cell; channels are classified into six subtypes (L, N, P, Q, R, and T)… …
9N-type calcium channel — Calcium channel, voltage dependent, N type, alpha 1B subunit Identifiers Symbols CACNA1B; BIII; CACNL1A5; CACNN; Cav2.2 External IDs …
10P-type calcium channel — calcium channel, voltage dependent, P/Q type, alpha 1A subunit Identifiers Symbol CACNA1A Alt. symbols Cav2.1, CACNL1A4, SCA6, MHP1, MHP IUPHAR Cav2.1 …
