How It Works

Competitive antagonist at both alpha-1 and beta-adrenergic receptors, reducing peripheral vascular resistance and cardiac output.

Mechanism Steps

1Binds to alpha-1 adrenergic receptors on vascular smooth muscle, causing vasodilation and reduced peripheral resistance.
2Binds to beta-1 adrenergic receptors in the heart, reducing heart rate and contractility.
3Binds to beta-2 adrenergic receptors in bronchial and vascular smooth muscle, but effect is minimal due to alpha blockade.
