Acebutolol is used for treating hypertension, cardiac arrhythmia, and angina.
Acebutolol is used to treat high blood pressure and irregular heartbeat.
It helps by relaxing the narrowed blood vessels, makes it wider and thereby allows the blood to flow very easily resulting in low blood pressure.
The drug is contraindicated in people with following conditions:
Heart failure, poor circulation, and low blood pressure.
Persistent slow heart rate (bradycardia).
Atrioventricular block (AV block) in the heart.
Tumor of adrenal gland called as pheochromocytoma.
Known allergy to the drug.
For hypertension: Initial treatment is with 400 mg once a day or 200 mg twice a day. Maintenance dose is 400-800 mg per day.
For ventricular arrhythmia: Initial therapy is with 200 mg twice a day. Maintenance dose is 600 to 1200 mg per day in divided doses.

NSAIDs like ibuprofen and naproxen, which may block the effect of acebutolol on blood pressure.
Anticholinesterase drugs used in Alzheimer's disease like rivastigmine due to additive effect on the heart and blood pressure.
