Pharmacodynamics

Guanabenz, a centrally acting α-2 adrenergic agonist, is indicated for treatment of hypertension.

Mechanism of action

Guanabenz's antihypertensive effect is thought to be due to central alpha-adrenergic stimulation, which results in a decreased sympathetic outflow to the heart, kidneys, and peripheral vasculature in addition to a decreased systolic and diastolic blood pressure and a slight slowing of pulse rate. Chronic administration of guanabenz also causes a decrease in peripheral vascular resistance.
