Atenolol: Uses, Dosage, Side Effects, and More
From:
$8.25
Atenolol is a prescription beta-blocker used to treat high blood pressure, chest pain, and to improve survival after a heart attack (myocardial infarction). It works by slowing the heart rate and reducing the force of heart contractions, which helps lower blood pressure and reduce strain on the heart. Tenormin is often part of a long-term cardiovascular care plan to reduce the risk of complications such as stroke, heart failure, and heart attack recurrence.
