Diltiazem tablets contain 60 mg diltiazem hydrochloride. Diltiazem is a benzothiazepine calcium-channel blocker. It exerts its effect due to its vasodilator effect in the peripheral and coronary arteries, and limited negative inotropic properties (weakens the contraction of heart muscle).
Diltiazem tablets are used in the treatment of angina pectoris and hypertension.
