Table of contents:

Sectral is a prescription medication primarily used to treat high blood pressure and heart rhythm disorders such as arrhythmia. By lowering high blood pressure, it helps prevent strokes, heart attacks, and kidney problems. Treating irregular heartbeat helps the heart work better and with less strain.

Sectral is also known by its generic name, Acebutolol. It belongs to the class of drugs known as beta-blockers, specifically a selective, hydrophilic-beta-adrenoreceptor blocker with mild intrinsic sympathomimetic activity. It works by blocking the action of certain natural substances in the body, such as adrenaline.

Use and Dosage

Acebutolol tablets are taken orally with or without food as prescribed by your doctor, usually once or twice a day. Your dosage is determined based on your medical condition and response to the medication. Take Acebutolol tablets regularly to gain maximum benefit from it. You can take the tablet at the same time each day to help remember when to take it.

The recommended dosage of Acebutolol varies based on the medical condition being treated and the response to the medication. The usual maintenance dose for hypertension is between 400-1200 mg per day divided into one or two doses, but not exceeding 1200 mg per day. However, the initial dose may start at 200 mg twice a day and can be increased if needed. Follow the dosage instructions provided by your healthcare provider and do not adjust the dosage without consulting with them first.

When taking Acebutolol tablets to treat high blood pressure, it may take a few weeks before you experience the full benefits of the medication. Even if you feel well, continue to take the medication as prescribed by the doctor. Inform your doctor if you do not notice an improvement in your symptoms or if they worsen, such as if your routine blood pressure readings remain high or increase.

If you miss a dose of Sectral, take it as soon as you remember. However, if it is close to the time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed dose.
