Clinical Significance
Diltiazem is a nondihydropyridine (non-DHP) member of the class of drugs known as calcium channel blockers, used in the treatment of hypertension, angina pectoris, and some types of arrhythmia. It is a benzothiazepine, which differentiates it from the other classes of non-DHP calcium channel blockers such as the phenylalkylamines.
It is also an effective preventive medication for migraine. It is a class 3 antianginal drug, and a class IV antiarrhythmic. It is a common adulterant of cocaine seized in the UK,[1] and has been found to reduce cocaine cravings in rats, indicating it may prolong the "high" (see below). It incites minimal reflex sympathetic changes. It is based upon a 1,4-thiazepine ring.

Diltiazem is metabolized by and acts as an inhibitor of the CYP3A4 enzyme.
