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 ...
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
Calcium channel blockers. As the name suggests, these medications block calcium from entering your heart’s cells and arteries. This can relax and open up your blood vessels.
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.
Class IV agents are slow non-dihydropyridine calcium channel blockers. They decrease conduction through the AV node , and shorten phase two (the plateau) of the cardiac action potential . They thus reduce the contractility of the heart, so may be inappropriate in heart failure.
