Acebutolol is a medicine that helps lower blood pressure and control irregular heartbeats. It belongs to a class of drugs called beta-blockers.
Benazepril (Lotensin) is a medicine that lowers your blood pressure. Lowering blood pressure helps to prevent strokes and heart attacks.
Acebutolol is used to treat high blood pressure in adults. It can be used alone or with other blood pressure medicines. Acebutolol is also used to manage irregular heartbeats called ventricular arrhythmias. It helps to reduce the number of these irregular beats.
Benazepril is used to treat high blood pressure (hypertension). Lowering your blood pressure reduces your risk of heart attack and stroke. It can be used alone or with other blood pressure medicines.
Acebutolol works by blocking the effects of certain natural chemicals in your body, like adrenaline, on the heart and blood vessels. This helps to slow down the heart rate and lower blood pressure. It also helps to make the heart beat more regularly.

How to Read This acebutolol vs benazepril Comparison
acebutolol is classified in the Beta-1 Selective Blocker with ISA drug class, while benazepril sits within the ACE Inhibitor class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, acebutolol has 2,941 submissions while benazepril has 1,971. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. No direct interaction between these two drugs is listed in our FDA-derived dataset, though co-prescription still warrants pharmacist review. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for acebutolol or benazepril.
