Mechanism of action

Diltiazem blocks L-type calcium channels in the sinoatrial and atrioventricular nodes, slowing conduction velocity and increasing refractoriness. This results in negative chronotropic and dromotropic effects, reducing heart rate and contractility while also causing vasodilation of coronary and peripheral arteries. The intravenous formulation provides rapid onset for acute management of supraventricular arrhythmias and hypertensive episodes.
