Primary Uses
It treats high blood pressure (hypertension), prevents angina, manages irregular heartbeats (arrhythmias), and reduces the risk of heart complications after a heart attack.
How It Works
Atenolol works by affecting nerve impulses in the heart, decreasing the heart's need for blood and oxygen, and widening blood vessels to lower blood pressure.
Good to know: Noten is not considered addictive.
