Bepridil
A long-acting, non selective, calcium channel blocker with significant anti-anginal activity. The drug produces significant coronary vasodilation and modest peripheral effects. It has antihypertensive and selective anti-arrhythmia activities and acts as a calmodulin antagonist. It is no longer marketed in the United States, as it has been implicated in causing ventricular arrhythmias (ie. Torsade de pointes).
