Uses

Atenolol is used in the treatment of angina (chest pain), arrhythmias (abnormal heart beat), heart attack and increased blood pressure .

Atenolol belongs to class of medications called beta blockers. It acts by blocking receptors (beta-1 adrenergic receptor) in the heart and peripheral blood vessels resulting in slowing of heart rate and relaxing of blood vessels thereby lowering blood pressure.
