Prazosin is an alpha-adrenergic blocking agent used to treat hypertension and benign prostatic hyperplasia. The antihypertensive effect of Prazosin results from a decrease in systemic vascular resistance and the Mechanism of action.

Prazosin is a competitive alpha-1 adrenergic receptor blocker. By blocking alpha-1 receptors on muscle cesll that surround blood vessels, prazosin causes vasodilation (widening) of the blood vessels, and consequently decreases the resistance of blood flow. The overall benefit of its use is a decrease in blood pressure.
