Description

Atenolol is a beta-blocker drug used to treat high blood pressure, angina, and certain heart rhythm disorders. It works by blocking the action of certain natural chemicals in the body, such as epinephrine, on the heart and blood vessels. This results in a decrease in heart rate, blood pressure, and strain on the heart.

Common side effects of atenolol include fatigue, dizziness, depression, cold hands and feet, and insomnia. Other side effects may include nausea, vomiting, diarrhea, constipation, and decreased sex drive.

Brand names associated with atenolol include Tenormin, Tenoretic, and Tenoretic-A.
