SOTALOL HYDROCHLORIDE

Cardiovascular Approved 2000-05-01

Sotalol hydrochloride treats serious, life-threatening heart rhythm disturbances such as sustained ventricular tachycardia. It also helps patients with highly symptomatic atrial fibrillation or flutter maintain a normal heart rhythm once it has been restored. This medication is specifically used for patients with significant symptoms and is not typically used for those whose heart rhythm issues are easily corrected or cause minimal distress.

How SOTALOL HYDROCHLORIDE Works

Sotalol hydrochloride works by combining beta-blocking activity with the ability to prolong the duration of the heart's electrical action potential. By targeting these pathways, the drug helps stabilize heart rhythms and slow the resting heart rate. While its beta-blocking effects are seen at lower doses, the stabilization of the heart's electrical timing typically occurs at higher dosage levels.

SOTALOL HYDROCHLORIDE 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...
