Acebutol is a beta blocker commonly used in the treatment of high blood pressure (hypertension), angina (chest pain due to impaired blood supply to heart muscle), and certain types of arrhythmia (abnormal heart rhythms) in which the heart beats too rapidly. Acebutolol works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.


Acebutolol comes as an oral capsule and is taken as prescribed, usually once or twice a day. Possible side effects include dizziness, lightheadedness, lethargy, headache, constipation, diarrhea, upset stomach, and muscle aches.
