Mechanism of Action

Verapamil is a peripheral and coronary vasodilator. It also slows conduction through the AV node, and thus slows the increased ventricular response rate that occurs in atrial fibrillation and flutter. Verapamil works by lowering your blood pressure and makes it easier for your heart to pump blood around your body. In angina, verapamil works by improving the blood and oxygen supply to your heart. Angina is chest pain that comes on when not enough blood gets to the muscles of the heart. This usually happens because the arteries going to the heart become hardened and narrowed.

Route of Administration

Verapamil may be given intravenously or orally, as the hydrochloride; doses are expressed in terms of verapamil hydrochloride.
