VERAPAMIL (Isoptin, Calan)
Name/Class: VERAPAMIL (Isoptin, Calan)/Calcium Channel Blocker
Description: Verapamil is a calcium channel blocker that slows AV conduction, suppresses reentry dysrhythmias such as PSVT, and slows ventricular responses to atrial tachydysrhythmias. Verapamil also dilates
coronary arteries and reduces myocardial oxygen demand.
Indications: PSVT refractory to adenosine, atrial flutter, and atrial fibrillation with rapid ventricular response.
Contraindications: Severe hypotension, cardiogenic shock, 2nd- or 3rd-degree heart block, CHF, sinus node disease, and accessory AV pathways, WPW syndrome. It should not be administered to persons taking
beta blockers.
Precautions: MI with coronary artery occlusion, or myocardial stenosis.
Dosage/Route: 2.5 to 5 mg IV bolus over 2 to 3 min, then 5 to 10 mg after 15 to 30 min to a max of 30 mg in 30 min
