Atenolol, is a medication often prescribed for various cardiovascular conditions. It belongs to a class of drugs known as beta-blockers and primarily serves to regulate heart function. It achieves this by blocking the action of adrenaline (epinephrine) on specific receptors in the heart and blood vessels. Common uses of atenolol include treating hypertension (high blood pressure), angina (chest pain), and certain irregular heart rhythms. Additionally, it can be part of the treatment plan for heart attacks and may be used to prevent migraines in some cases.

Dosages of atenolol can vary depending on the condition it’s being used to treat and individual patient factors. Typically, it is taken orally in the form of tablets or capsules, with the specific dosing regimen determined by a healthcare provider.
