What is this medication?

SOTALOL (SOE ta lole) prevents and treats a fast or irregular heartbeat (arrhythmia). It is often used to treat a type of arrhythmia known as AFib (atrial fibrillation). It works by slowing down overactive electric signals in the heart, which stabilizes your heart rhythm. It also lowers your heart rate. It belongs to a group of medications called antiarrhythmics.
