Mechanism of action

Diltiazem is a non-dihydropyridine calcium channel blocker that inhibits the inward movement of calcium ions through L-type calcium channels in the sinoatrial and atrioventricular nodes, as well as in vascular smooth muscle. This results in decreased automaticity and conduction velocity in the heart, reduced myocardial contractility, and vasodilation of coronary and peripheral arteries. These effects collectively reduce heart rate, lower blood pressure, and improve myocardial oxygen supply-demand balance.
