Overview

DESCRIPTION Acebutolol HCl, USP is a selective, hydrophilic beta-adrenoreceptor blocking agent with mild intrinsic sympathomimetic activity for use in treating patients with hypertension and ventricular arrhythmias. It is marketed in capsule form for oral administration. Acebutolol HCl capsules, USP are provided in two dosage strengths which contain 200 mg or 400 mg of acebutolol as the hydrochloride salt.

Uses

INDICATIONS AND USAGE Hypertension Acebutolol HCl capsules are indicated for the management of hypertension in adults. It may be used alone or in combination with other antihypertensive agents, especially thiazide-type diuretics. Ventricular Arrhythmias Acebutolol HCl capsules are indicated in the management of ventricular premature beats; it reduces the total number of premature beats, as well as the number of paired and multiform ventricular ectopic beats, and R-on-T beats.

Dosage

DOSAGE AND ADMINISTRATION Hypertension The initial dosage of acebutolol in uncomplicated mild-to-moderate hypertension is 400 mg. This can be given as a single daily dose, but in occasional patients twice daily dosing may be required for adequate 24-hour blood-pressure control. An optimal response is usually achieved with dosages of 400 to 800 mg per day, although some patients have been maintained on as little as 200 mg per day. Patients with more severe hypertension or who have demonstrated inadequate control may respond to a total of 1200 mg daily (administered b.i.d.), or to the addition of a second antihypertensive agent. Beta-1 selectivity diminishes as dosage is increased. Ventricular Arrhythmia The usual initial dose of acebutolol is 400 mg daily given as 200 mg b.i.d.

Side Effects

ADVERSE REACTIONS Acebutolol is well tolerated in properly selected patients. Most adverse reactions have been mild, not required discontinuation of therapy, and tended to decrease as duration of treatment increases. The following table shows the frequency of treatment-related side effects derived from controlled clinical trials in patients with hypertension, angina pectoris, and arrhythmia. These patients received acebutolol, propranolol, or hydrochlorothiazide as monotherapy, or placebo. The following selected (potentially important) side effects were seen in up to 2% of acebutolol patients: Cardiovascular: hypotension, bradycardia, heart failure. Central Nervous System: anxiety, hyper/hypoesthesia, impotence. Dermatological: pruritus. Gastrointestinal: vomiting, abdominal pain.

Warnings

WARNINGS Cardiac Failure Sympathetic stimulation may be essential for support of the circulation in individuals with diminished myocardial contractility, and its inhibition by β-adrenergic receptor blockade may precipitate more severe failure. Although β-blockers should be avoided in overt cardiac failure, acebutolol can be used with caution in patients with a history of heart failure who are controlled with digitalis and/or diuretics. Both digitalis and acebutolol impair AV conduction. If cardiac failure persists, therapy with acebutolol should be withdrawn. CONTRAINDICATIONS Acebutolol HCl is contraindicated in: 1) persistently severe bradycardia; 2) second- and third-degree heart block; 3) overt cardiac failure; and 4) cardiogenic shock (see WARNINGS ).
