Why it is prescribed (Indications)
Messages from nerves are transferred to the heart by special chemicals known as neurotransmitters. The neurotransmitters (adrenaline and noradrenaline) bind to tiny areas on the heart known as beta receptors, to convey their message. Acebutolol binds with these beta receptors and does not allow the messages from adrenaline and noradrenaline to reach the heart. As a result, the heart beats slowly and with lesser force. Slow beating of the heart reduces the blood flow in blood vessels and thus reduces the inside pressure on the walls and controls your hypertension. The drug controls abnormally fast and uneven heart rate in the case of cardiac arrhythmia. Since the heart treated with acebutolol beats slowly and with less force, it uses lesser energy and thus chest pain in angina is relieved.
Missed a Dose?

Warnings and Precautions
