Acebutolol is a medication used to treat hypertension and cardiac arrhythmias. Acebutolol is a cardio selective beta blocker with intrinsic sympathomimetic activity, and so is infinitely more suitable than non-cardioselective beta blockers for patients with chronic obstructive pulmonary disease or asthma due to the fact that doses lower than 800mg daily have only 10-30% of the constricting effects on the bronchial system that treatments such as propanolol may have.

Acebutolol is also recommended over other beta blockers due to the lack of impact on the serum lipids; cholesterol and triglycerides.

A common side effect (10-30% of patients) includes the development of anti nuclear antibodies.
