Atenolol (Beta Nicardia) is a β1-selective adrenergic-blocking agent. It competitively blocks adrenergic stimulation of β1-adrenergic receptors within the myocardium and vascular smooth muscle. Low doses of Atenolol (Beta Nicardia) selectively inhibit cardiac and lipolytic β1-receptors but with little effect on the β2-adrenergic receptors of bronchial and vascular smooth muscle. At high doses (ie, >100 mg daily), this selectivity of Atenolol (Beta Nicardia) for β1-adrenergic receptors may diminish and the drug may competitively block β1- and β2-adrenergic receptors. Atenolol (Beta Nicardia) does not exhibit any intrinsic sympathomimetic Activity nor any membrane-stabilizing Activity.
