	Description	Diltiazem is a benzothiazepine derivative with antihypertensive and vasodilating properties. Approved in 1982 by the FDA, it is a member of the non-dihydropyridine calcium channel blockers drug class. It works through various mechanisms of action, but it primarily works by inhibiting the calcium influx into cardiac and vascular smooth muscle during depolarization.[L10556] Compared to dihydropyridine drugs, such as [nifedipine], that preferentially act on vascular smooth muscle and [verapamil] that directly acts on the heart muscle, diltiazem displays an intermediate specificity to target both the cardiac and vascular smooth muscle.[T28] Being a potent vasodilator, diltiazem is used clinically as an antihypertensive, anti-arrhythmic, and as an anti-anginal agent [L6289] for the management of cardiovascular conditions such as hypertension, chronic stable angina, atrial fibrillation, atrial flutter. Apart from its main FDA-approved indications, diltiazem has also been used for numerous off-label indications, such as anal fissures (in topical formulations), migraine prophylaxis, pulmonary hypertension, and rest-related cramps in the lower extremities.[L6289] Typically available in extended-release oral and intravenous formulations, diltiazem is marketed under various brand names with Cardizem and Tiazac being the most common ones.
