Calcium Channels

Calcium channel blockers act on voltage-gated channels that let calcium ions enter excitable cells. Voltage-gated calcium (CaV) channels couple membrane depolarization to muscle contraction, neurotransmitter release and gene expression. Channel types are classed as L-, N-, P/Q-, R- and T-type according to their electrophysiological and pharmacological properties. The pore-forming α1 subunit of the L-type channel was first sequenced in 1987 as the skeletal muscle receptor for calcium channel blockers. Dihydropyridines in this category include isradipine, nimodipine and amlodipine besylate, which bind L-type channels. The benzothiazepine diltiazem HCl acts on the same channel type at a distinct binding site. BAPTA/AM, the cell-permeant ester of a calcium chelator, is listed for buffering intracellular calcium rather than for blocking channels.
