Applications & Uses
Uses
β-blockers. Clinical application in the treatment of hypertension, angina and arrhythmia.
Uses
Selective b1 adrenergic receptor agonist, anti-hypertensive, anti-anginal, anti-arrhythmic
Uses
Atenolol is 2-[4′[2-hydroxy-3-(iso-propylamino)propoxy]phenyl]acetamide (12.1.7) [11–13].Atenolol is a selective β1-adrenoblocker, or in other words, a cardioblocker. Like acebutol, atenolol possesses antianginal, antihypotensive, and antiarrhythmic action. It is used for arterial hypotension, preventing attacks of angina, sinus tachycardia, and preventing supraventricular tachyarrhythmia.
Uses
It is used for preventing angina pectoris.
