What is Atenolol?
Atenolol is a beta-blocker that has an effect on the heart and blood circulation (the flow of blood through the arteries and veins). Atenolol is used to treat angina (chest discomfort) and excessive blood pressure (high blood pressure). Atenolol is also used to decrease the chance of mortality following a heart attack.
How does it work?
Atenolol is a beta-blocker that is selective for beta1 (that is, it preferentially acts on the beta1-adrenergic receptors in the heart). With increasing dosage, selectivity diminishes. Atenolol lacks intrinsic sympathomimetic action and membrane stability, and it exhibits negative inotropic effects like other beta-blockers (and is therefore contraindicated in uncontrolled heart failure).
The mechanism of action of atenolol in the treatment of high blood pressure, like that of other beta-blockers, is not entirely known.
Because atenolol reduces heart rate and contractility, it is expected to be useful in eliminating or lowering symptoms in angina patients.
The increased secondary features of S (-) atenolol compared to the racemic combination are unlikely to augment the various therapeutic benefits.
In most ethnic groups, atenolol is effective and well tolerated, while the reaction in black people may be lower.
What are the benefits of taking it?
Atenolol is a beta-blocker medication, which means it affects your heart and circulatory system. Atenolol is prescribed for excessive blood pressure, angina, cardiac arrhythmias (to produce a regular and sufficient 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.
Adults
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.

Why can't I get this medicine on the NHS?
Many patients have reported that it has become difficult to obtain liquid version of their medicines when they are having difficulty taking more traditional dose forms.
Instead of prescriptions for manufactured solutions or suspensions, some patients are being advised to use a crushed tablet dissolved in water to achieve a liquid version of their medicine.
Unfortunately, this isn’t always a suitable or convenient option for some patients.
