The treatment of cardiac arrhythmias has changed over the past several years, as concerns have grown about proarrhythmias and increased mortality associated with certain antiarrhythmic agents. Sotalol, a unique racemic compound with both Class II (beta-blocking) and Class III (repolarization-prolonging) properties, effectively controls life-threatening arrhythmias and has a favorable safety profile, especially when compared with traditional antiarrhythmic drugs. A review of clinical trials demonstrates that sotalol is an effective treatment for premature ventricular complexes, ventricular tachycardia, and ventricular fibrillation. Moreover, it significantly reduces cardiac and all-cause mortality in these patient populations. Although sotalol currently is approved in the United States only for the treatment of life-threatening ventricular arrhythmias, it also is active against several supraventricular arrhythmias. Sotalol is safe and generally well tolerated; most of the adverse effects experienced with its use are related to its beta-blocking activity. However, sotalol has been associated with life-threatening proarrhythmias, including torsades de pointes, but the incidence of this adverse effect is low. Unlike pure Class II agents, sotalol usually is well tolerated in patients with mild-to-moderate left ventricular dysfunction and rarely causes new or worsening congestive heart failure. Sotalol represents an advance in the treatment and prevention of symptomatic ventricular arrhythmias and appears to be a reasonable first-line choice when the arrhythmia is life threatening.
