Bepridil (trade name Vascor) is a calcium channel blocker once used to treat angina. It is no longer sold in the United States.

It is nonselective.[1]

It has been discussed as a possible option in the treatment of atrial fibrillation.[2]

It has been implicated in causing ventricular arrhythmia (Torsade de pointes).
