Atenolol is a drug to treat chest pain and lower blood pressure in people with hypertension. This drug may also be used in the treatment of heart rhythm disturbances (arrhythmias) and treatment after a heart attack .

Atenolol belongs to the class of beta blockers ( beta blockers ). This drug works by slowing the heart rate and reducing the strength of the heart in pumping blood so that blood pressure decreases. As the heart activity decreases, the risk of angina will also decrease.
