Bepridil is a calcium channel blocker that has well characterized anti-anginal properties and known but poorly characterized type 1 anti-arrhythmic and anti-hypertensive properties. It has inhibitory effects on both the slow calcium and fast sodium inward currents in myocardial and vascular smooth muscle, interferes with calcium binding to calmodulin, and blocks both voltage and receptor operated calcium channels. It is used to treat hypertension (high blood pressure), angina (chest pain), sustained atrial fibrillation and tachyarrhythmia. The most common side effects were upper gastrointestinal complaints (nausea, dyspepsia or GI distress), diarrhea, dizziness, asthenia and nervousness. Certain drugs could increase the likelihood of potentially serious adverse effects with bepridil hydrochloride. In general, these are drugs that have one or more pharmacologic activities similar to bepridil hydrochloride, including anti-arrhythmic agents such as quinidine and procainamide, cardiac glycosides and tricyclic anti-depressants. Anti-arrhythmics and tricyclic anti-depressants could exaggerate the prolongation of the QT interval observed with bepridil hydrochloride. Cardiac glycosides could exaggerate the depression of AV nodal conduction observed with bepridil hydrochloride.

Bepridil (trade name Vascor) is an amine calcium channel blocker used to treat angina. Bepridil is a calcium channel blocker that has well characterized anti-anginal properties and known but poorly characterized type 1 anti-arrhythmic and anti-hypertensive properties. It is not related chemically to other calcium channel blockers such as diltiazem hydrochloride, nifedipine and verapamil hydrochloride. Bepridil has inhibitory effects on both the slow calcium (L-type) and fast sodium inward currents in myocardial and vascular smooth muscle, interferes with calcium binding to calmodulin, and blocks both voltage and receptor operated calcium channels. Bepridil inhibits the transmembrane influx of calcium ions into cardiac and vascular smooth muscle. This has been demonstrated in isolated myocardial and vascular smooth muscle preparations in which both the slope of the calcium dose response curve and the maximum calcium-induced inotropic response were significantly reduced by bepridil. In cardiac myocytes in vitro, bepridil was shown to be tightly bound to actin. Bepridil regularly reduces heart rate and arterial pressure at rest and at a given level of exercise by dilating peripheral arterioles and reducing total peripheral resistance (afterload) against which the heart works. Bepridil is no longer sold in the United States, but it is still marketed in other countries. Bepridil has antihypertensive and selective anti-arrhythmia activities and acts as a calmodulin antagonist. Although, it contains one chiral center, it is generally administered as a racemates. The drug bepridil is a racemic mixture of two enantiomers for the 2R as CID 16048570 and 2S as CID 445143. (R)-isomer of bepridil is more active than (-S)- isomer, in certain cases. In the retrogradely perfused, paced rat heart the higher activity was found for the (+)-enantiomer, which was 4.27 times more potent in increasing coronary flow than the (-)-isomer. The two enantiomers of bepridil showed a lower activity on maximum systolic left ventricular pressure (MSLVP) than on coronary flow, and a similar 3-4 fold stereoselectivity with both parameters.
