Aug 5, 2022 · Calcium channel antagonists block the inward movement of calcium by binding to the L-type “long-acting” voltage-gated calcium channels in the heart, vascular smooth muscle, and pancreas. There are two major categories of calcium channel antagonists based on their primary physiologic effects.

Calcium channel blockers reduce the amount of calcium that goes into these muscle cells. This causes these muscle cells to relax. So, the effects of these medicines are: To widen the arteries, which: Reduces the blood pressure. Helps to treat angina by widening the coronary arteries. Can ease symptoms of Raynaud's phenomenon.L-type calcium channel blockers selectively inhibit these action potentials in smooth muscle which leads to dilation of blood vessels; this in turn corrects hypertension.
