Also, show high sensitivity to calcium channel blockers. T-Type calcium channels are also referred to as low-voltage activated channels. They contain the Cav3 family of a1 subunits. They are distinguished by their voltages of activation, which occur at negative membrane potential. They are particularly important in the cardiovascular system ...In the 1970s, calcium channel antagonists, also known as calcium channel blockers, were widely used for many indications. This cardiovascular drug class is one of the leading causes of drug-related fatalities. They often classify into two major categories, either non-dihydropyridines or dihydropyridines.
