The Mechanism of Action of Coreg Beta Blocker

As a non-selective Beta blocker, Coreg exercises its action by blocking beta-adrenergic receptors located in the body. This block affects the sympathetic nervous system, specifically the two types of beta, beta-1 and beta-2 receptors. In doing so, Coreg influences several physiological processes that are regulated by these receptors.

Coreg’s mechanism of action is to block beta-adrenergic receptors, affecting the sympathetic nervous system and various physiological processes.

1. Inhibition of Beta-1 Receptors:

One of Coreg’s key actions is the inhibition of beta-1 receptors in the heart. Beta-1 receptors are mainly in the cardiac tissue and are responsible for regulating heart rate and strength of cardiac contractions. When blocking these receptors, CORG reduces the effects of the sympathetic nervous system, which causes a decrease in heart rate and contraction force.

  1. The inhibition of beta-1 receptors in the heart by Coreg leads to:
    • Heart rate reduction
    • Decreased contractility
    • Decreased cardiac output

2. Antagonism of Beta-2 Receptors:

In addition to beta-1 receptors, CORG also antagonizes beta-2 receptors. Beta-2 receptors are mainly located in the smooth muscles that cover bronchial airways and peripheral blood vessels. When blocking these receptors, COREG causes the relaxation of the smooth muscles, which results in a widening of the respiratory tract and the dilation of the blood vessels.

  1. The antagonism of the beta-2 receptors by CORG produces:
    • Broncodilación
    • Vasodilation
    • Blood flow improvement

COREG inhibition of beta-1 receptors in the heart decreases heart rate, contractility and cardiac output, while their antagonism of beta-2 receptors causes bronchodilation and vasodilation.

In general, the mechanism of action of beta blocker Coreg consists in the blockade of betaadrenergic receptors, which produces various beneficial effects beneficial for the treatment of diseases such as hypertension, heart failure and angina peer. This knowledge of the COREG mechanism of action helps health professionals to prescribe the medicine properly and control its effects on patients.
