Question

Quizplus · Accepted Answer

Captopril is an ACE inhibitor, which blocks the conversion of angiotensin I to angiotensin II, leading to vasodilation and decreased blood pressure. Reserpine is a sympatholytic medication that depletes norepinephrine, dopamine, and serotonin from sympathetic nerve endings, leading to decreased vasomotor tone and blood pressure. Clonidine is a centrally acting alpha-2 agonist that lowers blood pressure by reducing sympathetic outflow. Labetalol is a non-selective beta-blocker with alpha-1 blocking properties, which lowers blood pressure by decreasing cardiac output and peripheral resistance.
