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 .
ATC code C08 Calcium channel blockers is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. [1] [2] [3] Subgroup C08 is part of the anatomical group C Cardiovascular system ...
N-type calcium channels are categorized as high threshold-activated channels and seen in the Cav2 gene family. The structure of the N-type calcium channel is very similar to other voltage-dependent channels. The most important part of the channel is the actual pore that is formed by the α1B subunit.
Isradipine (tradenames DynaCirc, Prescal) is a calcium channel blocker of the dihydropyridine class. It is usually prescribed for the treatment of high blood pressure in order to reduce the risk of stroke and heart attack. It was patented in 1978 and approved for medical use in 1989. [1]
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.

Zalicus Presents Data on Novel, Oral, N- and T-Type Calcium Channel Blockers for the Treatment of Pain Preclinical Data on Z160 and Z944 Presented at the American Pain Society 2013 Annual Meeting ...
Calcium channel blockers (CCBs) preferentially block the L-type voltage-gated calcium channels to prevent the flow of calcium influx in the blood vessels and the heart, thereby reducing peripheral vascular resistance and cardiac output respectively. [10] Dihydropyridines (DHP): amlodipine, nifedipine, felodipine, nicardipine
Amlodipine, sold under the brand name Norvasc among others, is a calcium channel blocker medication used to treat high blood pressure, coronary artery disease (CAD) [10] and variant angina (also called Prinzmetal angina or coronary artery vasospasm, among other names). [11]
