Generic Name: Atenolol
Product Name: healthsense Atenolol

Indication

Atenolol is used to treat high blood pressure, angina, and abnormal heart rhythms and is also given after a heart attack

Action

Atenolol is a beta-Adrenoceptor blocking agent that acts on beta-receptors in the heart. It slows the heart rate and also reduces the force that the heart must contract with. These two actions reduce the total workload of the heart and help to relieve angina. Atenolol treats cardiac arrhythmias by reduces the sensitivity of conduction cells in the heart to electrical impulses making them less likely to produce abnormal rhythms. The mechanism buy which atenolol lowers blood pressure is unknown
