Mechanism of Action

Carvedilol inhibits exercise-induced tachycardia through its inhibition of beta adrenoceptors.

Carvedilol’s action on alpha-1 adrenergic receptors relaxes smooth muscle in vasculature, leading to reduced peripheral vascular resistance and an overall reduction in blood pressure. At higher doses, calcium channel blocking and antioxidant activity can also be seen. The antioxidant activity of carvedilol prevents oxidation of low-density lipoprotein and its uptake into coronary circulation.
