About this active substance

Atenolol is a beta-blocker medication used to treat high blood pressure, angina pectoris, and to prevent myocardial infarction. It works by blocking beta-adrenergic receptors, reducing heart rate, blood pressure, and the heart's oxygen demand.

It is indicated for controlling hypertension, reducing the risk of cardiovascular complications such as strokes or heart attacks. It is also used to treat cardiac arrhythmias and to prevent migraines.

Atenolol is taken orally in tablet form, with the dosage adjusted based on the condition being treated and the patient's response.

Side effects may include fatigue, dizziness, bradycardia (slow heart rate), cold hands and feet, nausea, or sleep disturbances. It is contraindicated in patients with severe bradycardia, decompensated heart failure, or severe asthma.
