Atenolol
Atenolol (Tenormin) is a beta blocker used for high blood pressure, angina and to improve survival after a heart attack. This catalogue lists Tenormin and Tenoretic tablets, including one combination with chlorthalidone.
Key points
- Tenormin contains atenolol alone, while Tenoretic contains atenolol with the diuretic chlorthalidone.
- Atenolol is a beta1-selective beta blocker, meaning it acts mainly on beta1 receptors in the heart.
- For people with coronary artery disease, an atenolol label’s boxed warning advises against abruptly stopping atenolol, as sudden cessation has been linked to worse angina, heart attack and dangerous heart rhythms.
What Atenolol is used for
Tenormin is listed for Hypertension and Angina Pectoris, with myocardial infarction also among its listed indications. Atenolol is used to improve survival after a heart attack and works by relaxing blood vessels and slowing the heart rate.
