Acebutolol is a cardioselective, beta-adrenoreceptor blocking agent, which possesses mild intrinsic sympathomimetic activity (ISA) in its therapeutically effective dose range. In general, beta-blockers reduce the work the heart has to do and allow it to beat more regularly. Acebutolol has less antagonistic effects on peripheral vascular ß2-receptors at rest and after epinephrine stimulation than nonselective beta-antagonists. Low doses of acebutolol produce less evidence of bronchoconstriction than nonselective agents like propranolol but more than atenolol.
- Mechanism of action
Acebutolol is a selective β1-receptor antagonist. Activation of β1-receptors by epinephrine increases the heart rate and the blood pressure, and the heart consumes more oxygen. Acebutolol blocks these receptors, lowering the heart rate and blood pressure. This drug then has the reverse effect of epinephrine. In addition, beta blockers prevent the release of renin, which is a hormone produced by the kidneys which leads to constriction of blood vessels.
Target Actions Organism ABeta-1 adrenergic receptor partial agonistHumans UBeta-2 adrenergic receptor partial agonistHumans - Absorption

- Metabolism
Subject to extensive first-pass hepatic biotransformation (primarily to diacetolol).
- Route of elimination
Elimination via renal excretion is approximately 30% to 40% and by non-renal mechanisms 50% to 60%, which includes excretion into the bile and direct passage through the intestinal wall.
- Half-life
The plasma elimination half-life is approximately 3 to 4 hours. The half-life of its metabolite, diacetolol, is 8 to 13 hours.

Drug Interaction Integrate drug-drug
interactions in your softwareAbaloparatide The risk or severity of adverse effects can be increased when Acebutolol is combined with Abaloparatide. Abatacept The metabolism of Acebutolol can be increased when combined with Abatacept. Abiraterone The metabolism of Acebutolol can be decreased when combined with Abiraterone. Acarbose The therapeutic efficacy of Acarbose can be increased when used in combination with Acebutolol. Aceclofenac Aceclofenac may decrease the antihypertensive activities of Acebutolol. - Food Interactions
- Take with or without food. Food decreases absorption rate and maximum concentration, but not to a clinically significant extent.
