Metoprolol: A Comprehensive Guide on Its Uses, Mechanism, and Dosage Forms

Metoprolol is a beta-1 selective β-adrenergic blocking agent that is commonly used to manage several health conditions and improve heart function.

Uses:

It primarily treats hypertension high blood pressure, prevents chest pn due to heart disease, reduces the risk of hospitalization for heart flure, and decreases the chances of having another heart attack after a previous one. Metoprolol also helps lower the risk of death in individuals who have experienced a heart attack.

Mechanism of Action:

Metoprolol works by blocking β receptors on the heart muscle. When these receptors bind to hormones such as norepinephrine and epinephrine adrenaline, they cause the heart rate, force, and conduction speed to increase. Metoprolol blocks this action, slowing down the heart's rhythm and enhancing its efficiency, which helps in lowering blood pressure and improving overall cardiac function.
