Definition

1. Noun:
   • A beta-blocker medication: Atenolol is a prescription drug belonging to the class of beta-adrenergic blocking agents (beta-blockers). It works by blocking the action of certain natural chemicals in the body, such as epinephrine, on the heart and blood vessels. This effect slows the heart rate, lowers blood pressure, and reduces the heart's demand for oxygen.
