Acebutolol is a new hydrophilic, cardioselective beta-adrenergic-blocking agent that possesses partial agonist and membrane-stabilizing activities. In the treatment of mild to moderate essential hypertension, once-daily acebutolol as monotherapy provides effective control in a large majority of patients and produces a

The clinical pharmacology and pharmacokinetics of acebutolol are summarized. Acebutolol and its longer-acting metabolite, diacetolol, are rapidly absorbed into the circulation from the gastrointestinal tract, and their bioavailability, unlike that of propranolol and metoprolol, is not significantly altered by whether
