General Info:

Atenolol is used to treat high blood pressure. It also is used to prevent angina (chest pain) and heart attacks. Hypertension: Atenolol is indicated in the management of hypertension. It may be used alone or concomitantly with other antihypertensive agents, particularly with a thiazide-type diuretic. Angina Pectoris Due to Coronary Atherosclerosis: Atenolol is indicated for the long-term management of patients with angina pectoris.

Tenormin, a type of medication known as a beta blocker, is used in the treatment of high blood pressure, angina pectoris (chest pain, usually caused by lack of oxygen in the heart muscle due to clogged arteries), and heart attack. When used for high blood pressure it is effective alone or combined with other high blood pressure medications, particularly with a thiazide-type water pill (diuretic). Beta blockers decrease the force and rate of heart contractions.

Occasionally doctors prescribe Tenormin for treatment of alcohol withdrawal, prevention of migraine headache, and bouts of anxiety.
