Atenolol is a drug that belongs to the class of beta-blockers (or beta-blockers), which is generally used in the treatment of high blood pressure, coronary ischemic disease, and some types of cardiac arrhythmias. Atenolol, like other beta-blockers, is indicated in the treatment of cardiovascular diseases since they have a direct action on the heart rate and on the force of contraction of the heart muscle, thus reducing the energy demand of the heart.

About Atenolol Tablets

Buy Atenolol online from a UK pharmacy.

Atenolol belongs to a group of medicines called beta blockers. It is used to treat high blood pressure and irregular heartbeats (arrhythmia). It can also be used to prevent chest pain caused by angina. If you have high blood pressure, taking atenolol helps prevent future heart disease, heart attacks and strokes. Atenolol slows down your heart rate and makes it easier for your heart to pump blood around your body.

People also ask

What is Atenolol?

Atenolol is a beta-blocker that affects the heart and circulation (the flow of blood through the arteries and veins). Atenolol is used to treat angina (chest pain) and hypertension (high blood pressure). Atenolol is also used to lower the risk of death after a heart attack.

How does it work?

Atenolol is a beta1-selective beta-blocker (that is, it preferentially acts on the beta1-adrenergic receptors in the heart). Selectivity decreases with increasing dose. Atenolol lacks intrinsic sympathomimetic activity and membrane stabilization, and like other beta-blockers, has negative inotropic effects (and is therefore contraindicated in uncontrolled heart failure).

Like other beta-blockers, the mechanism of action of atenolol in the treatment of high blood pressure is not fully understood.

Atenolol's action on reducing heart rate and contractility is likely to make it effective in eliminating or reducing symptoms in patients with angina.

It is unlikely that the additional secondary properties that S (-) atenolol possesses, compared to the racemic mixture, will increase the different therapeutic effects.

Atenolol is effective and adequately tolerated in most ethnic populations, although the response may be lower in black individuals.

What are the benefits of taking it?

Atenolol belongs to a group of medicines called beta-blockers, that is, it works on your heart and circulatory system. Atenolol uses include being indicated in the treatment of high blood pressure, angina, cardiac arrhythmias (to achieve a regular and adequate heartbeat rhythm), and acute myocardial infarction (to protect the heart during and after the infarction).

How do I use it and its dosage?

Always use these high blood pressure tablets exactly as your doctor or pharmacist has told you. If in doubt, ask your doctor or pharmacist again.

The recommended dosage is 50-100 mg daily (1 or 2 atenolol tablets 50 mg).

This medicine is usually taken once a day, although the daily dose can also be divided into two doses.

  • Atenolol tablets should be swallowed whole with the help of a little water.
  • Try to take your tablet at the same time each day.
  • Your doctor will indicate the duration of your treatment with atenolol.
  • It is very important to continue taking atenolol for the time recommended by the doctor.
  • The tablet can be divided into equal doses. Do not stop taking your tablets, even if you feel well unless your doctor tells you to; In this case, you should do it gradually.


High blood pressure: the starting dose is 50 mg daily. The maximum effect occurs after 1-2 weeks of treatment. If the response is not sufficient, the dose can be increased to 100 mg. The efficacy does not usually increase if this dose is exceeded. A further reduction in blood pressure can be obtained by combining atenolol with other antihypertensive agents.

Chest pain (angina): Although this is usually also started at a dose of 50 mg per day, the effective dose is generally 100 mg in a single oral dose or two 50-mg doses per day.

Irregular heartbeat: after controlling the arrhythmias with intravenous treatment, the appropriate maintenance oral dosage is 50-100 mg/day, administered in a single dose.

Early protection after a heart attack: in patients in whom β-blocker treatment is indicated, it will be started intravenously and then continued orally, with 50 or 100 mg daily. If bradycardia and/or hypotension occur requiring treatment, or any other unwanted effects occur, this treatment should be discontinued.

Delayed protection after a heart attack: If several days have elapsed since acute myocardial infarction, an oral dose of atenolol of 100 mg/day is recommended as long-term prophylaxis.
