MoA (Mechanism of Action)

Propranolol: Propranolol is a non-selective beta-blocker, which means it blocks both beta-1 and beta-2 adrenergic receptors. By blocking these receptors, propranolol reduces the effects of adrenaline and other stress hormones on the heart, blood vessels, and other parts of the body. It slows down the heart rate and decreases the force of contractions, resulting in lower blood pressure. Additionally, propranolol inhibits the release of renin, a hormone that plays a role in regulating blood pressure and fluid balance in the body.

Metoprolol: Metoprolol is a selective beta-1 adrenergic receptor blocker. It primarily blocks beta-1 receptors in the heart, reducing the effects of stress hormones like adrenaline on the heart. By doing so, metoprolol slows down the heart rate, decreases the force of contractions, and lowers blood pressure. Unlike propranolol, metoprolol has less effect on beta-2 receptors in the lungs and blood vessels, making it a preferred choice in patients with respiratory conditions and peripheral vascular disease.

Similarities: Both propranolol and metoprolol are beta-blockers and share the common goal of reducing the effects of stress hormones on the heart and blood vessels. They both decrease heart rate, lower blood pressure, and are used to treat various cardiovascular conditions such as hypertension, angina, and arrhythmias.

Differences: While both medications are beta-blockers, there are differences in their selectivity for adrenergic receptors. Propranolol is non-selective and blocks both beta-1 and beta-2 receptors, whereas metoprolol primarily targets beta-1 receptors. This selectivity of metoprolol makes it better suited for patients with respiratory conditions or peripheral vascular disease, as it has lesser effects on beta-2 receptors found in the lungs and blood vessels. Additionally, the specific pharmacokinetic properties of each medication may vary, leading to differences in dosing, duration of action, and side effect profile.

Conclusion: While both propranolol and metoprolol are beta-blockers and share similarities in their MoA, they differ in their selectivity for adrenergic receptors. Propranolol is non-selective, blocking both beta-1 and beta-2 receptors, while metoprolol primarily targets beta-1 receptors. These differences in selectivity may influence their use in different patient populations and cardiovascular conditions.
