Sotalol Hydrochloride



What is Sotalol Hydrochloride 40 mg?

What is Sotalol Hydrochloride 40 mg? Betapace 40 mg is used to treat a serious (possibly life-threatening) type of fast heartbeat called sustained ventricular tachycardia. Sotalol Hydrochloride tablets are also used to treat certain fast/irregular heartbeats (atrial fibrillation/flutter) in patients with severe symptoms such as weakness and shortness of breath. Betapace generic helps to lessen these symptoms. It slows the heart rate and helps the heart to beat more normally and regularly. This medication is both a beta-blocker and an anti-arrhythmic.
