How does Calan (Verapamil) Tablet work?

Calan (Verapamil) Tablet is a calcium ion influx inhibitor or calcium ion antagonist. It applies its pharmacologic effects by modulating the influx of ionic calcium. It is across the cell membrane of the arterial smooth muscle as well as in contractile and conductile myocardial cells.

Calan (Verapamil) Tablet exerts antihypertensive effects by lessening systemic vascular resistance. It is usually reflex tachycardia or without orthostatic decreases in blood pressure. During dynamic or isometric exercise, Calan does not alter systolic cardiac function in patients with normal ventricular function. This also does not alter total serum calcium levels. Though, one report suggested that calcium levels above the normal range may alter the therapeutic effect of this medicine.
