How BETAPACE Works

Sotalol hydrochloride is a non-cardioselective beta-adrenergic blocker that exhibits both Vaughan Williams Class II (beta-adrenoreceptor blocking) and Class III (cardiac action potential duration prolongation) antiarrhythmic properties. By inhibiting beta-receptors and prolonging the refractory period of cardiac tissue, it slows the heart rate and stabilizes cardiac rhythm. While beta-blockade is evident at low doses, significant Class III electrophysiologic effects are dose-dependent and typically seen at higher daily doses.

BETAPACE Boxed Warning

LIFE-THREATENING PROARRHYTHMIA To minimize the risk of drug-induced arrhythmia, initiate or reinitiate oral sotalol in a facility that can provide cardiac resuscitation and continuous electrocardiographic monitoring. Sotalol can cause life-threatening ventricular tachycardia associated with QT interval prolongation. If the QT interval prolongs to 500 msec or greater, reduce the dose, lengthen the dosing interval, or discontinue the drug. Calculate creatinine clearance to determine appropriate do...
