Uses For This Medicine
Acebutolol is used alone or together with other medicines (such as hydrochlorothiazide) to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled .
Acebutolol is also used to treat certain heart rhythm problems (ventricular arrhythmia) .
Acebutolol is a beta-blocker. It works by affecting the response to nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of blood and oxygen is increased to the heart .
Acebutolol is available only with your doctor's prescription .
Before Using This Medicine

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

Appropriate studies have not been performed on the relationship of age to the effects of acebutolol in the pediatric population. Safety and efficacy have not been established .
Appropriate studies performed to date have not demonstrated geriatrics-specific problems that would limit the usefulness of acebutolol in the elderly. However, elderly patients are more likely to have age-related liver or kidney problems, which may require an adjustment of dosage in patients receiving acebutolol .
