Calcium channel blockers (CCB), calcium channel antagonists or calcium antagonists [2] are a group of medications that disrupt the movement of calcium (Ca 2+) through calcium channels. [3] Calcium channel blockers are used as antihypertensive drugs, i.e., as medications to decrease blood pressure in patients with hypertension.
Compared with certain other L-type calcium channel blockers (for example those of the phenylalkylamine class such as verapamil) that have significant action at the heart, the dihydropyridine calcium channel blockers lower blood pressure mainly by relaxing the smooth muscle of the blood vessel walls. [3]
Antihypertensive agents are classified according to their mechanism of actions. The most common classes prescribed are diuretics, angiotensin-converting enzyme inhibitors (ACEIs), angiotensin II receptor blockers (ARBs), calcium channel blockers (CCBs) and beta-blockers. Antihyperlipidemic agents most often prescribed are statins, ezetimibe and ...
Lercanidipine (trade name Zanidip, among others) is an antihypertensive (blood pressure lowering) drug. It belongs to the dihydropyridine class of calcium channel blockers, which work by relaxing and opening the blood vessels allowing the blood to circulate more freely around the body.
Studies have shown that the intrathecal injection of the calcium channel inhibitor ziconotide, to block the N-type calcium channels, have produced alleviation of intractable pain. [12] Blockade of the N-type calcium channel is a potential therapeutic strategy for the treatment of alcoholism. Because prolonged alcohol exposure over time has been ...
Calcium channel, voltage-dependent, L type, alpha 1D subunit (also known as Ca v 1.3) is a protein that in humans is encoded by the CACNA1D gene. [5] Ca v 1.3 channels belong to the Ca v 1 family, which form L-type calcium currents and are sensitive to selective inhibition by dihydropyridines (DHP).
Conversely, when open channel blockers bind to the cell they prevent the normal function of agonist binding. For example, voltage-gated channels open and close based on membrane potential and are critical in the generation of action potentials by their allowance of ions to flow down established gradients. However, open channels blockers can ...
Efonidipine is a dihydropyridine calcium channel blocker marketed by Shionogi & Co. of Japan.It was launched in 1995, under the brand name Landel (ランデル).The drug blocks both T-type and L-type calcium channels. [1]
