ATENOLOL (Tenormin) is used for decreasing death due to heart problems after a heart attack. Atenolol is a beta-blocker. Exactly how Atenolol works to decrease heart problems after a heart attack is not known.
ATENOLOL (Tenormin®) belongs to a group of medicines called beta-blockers. Beta-blockers reduce the workload on the heart and help it to beat more regularly. Atenolol controls, but does not cure, high blood pressure (hypertension). Atenolol also relieves chest pain (angina), and can be helpful after a heart attack. Sometimes atenolol is used to help prevent migraine headaches. Generic atenolol tablets are available.
