Beta-blockers effectively lower blood pressure and heart rate, and are widely used for treatment of hypertension, tachycardia, cardiac angina and heart failure in adults
Receptor specificity depends on the binding affinity between the ligand and the binding site on the receptor
There is controversy regarding the selection of beta-blockers in the Atenolol, a cardioselective beta-1 adrenergic antagonist, selectively binds to the beta-1 adrenergic receptors in vascular smooth muscle and the heart
Atenolol is a cardioselective beta-blocker, called such because it selectively binds to the β1-adrenergic receptor as an antagonist up to a reported 26 fold more than β2
are the more potent blockers of β1-AR than β2-AR and produce better cardioselective

Atenolol is a cardioselective beta-blocker, called such because it selectively binds to the β1-adrenergic receptor as an antagonist up to a reported 26 fold more than β2 receptors
However, this selectivity diminishes as the

Atenolol comes only as a tablet you take by mouth
What is atenolol? Atenolol is a beta-blocker that affects the heart and circulation (blood flow
Atenolol is a drug that binds to β1-adrenergic receptors reducing blood pressure
It inhibits selectively beta-1 receptors with a lower affinity for beta-2 receptor subtype
- Mechanism of Action Because beta-blockers affect your heart and circulatory systems, they can have a wide range of side effects

Atenolol is a cardioselective beta-blocker, called such because it selectively binds to the β1-adrenergic receptor as an antagonist up to a reported 26 fold more than β2 receptors
1 β-Blockers are among the most widely prescribed of all drug classes, with more than 120 million

Its profile of action most closely resembles that of metoprolol which differs only in that it has some membrane stabilising activity
Selective beta-blockers are cardioselective
Metabolic and cardiovascular effects of carvedilol and atenolol in non-insulin- dependent diabetes mellitus and hypertension: a Atenolol works by preventing activity of certain receptors in the heart, thereby reducing blood pressure and heart rate
