Sotalol
Sotalol
Sotalol (pronounced soh-TAH-lohl) is a medication used to treat abnormal heart rhythms. It is classified as a beta blocker and an antiarrhythmic.
Etymology
The term "Sotalol" is derived from the chemical name SOdium Tert-butylamino-O-2-hydroxypropiophenone. The "L" at the end is a common suffix used in drug nomenclature.
Usage
Sotalol is used to help keep the heart beating normally in people with certain heart rhythm disorders, such as atrial fibrillation, atrial flutter, and ventricular arrhythmia. It is a beta-blocker that affects the heart and circulation (blood flow through arteries and veins).
Side Effects
Common side effects of Sotalol include fatigue, slow heart rate, and dizziness. Serious side effects may include heart failure, a new or worsening arrhythmia, or QT prolongation, which can cause serious (rarely fatal) fast/irregular heartbeat and other symptoms such as severe dizziness, fainting that need medical attention right away.
