Mechanism of action

ARBs selectively antagonize the AT1 receptor on vascular smooth muscle and adrenal tissue, blocking the effects of angiotensin II. This prevents vasoconstriction, reduces aldosterone-mediated sodium and water retention, and decreases sympathetic nervous system activation. The result is reduced peripheral vascular resistance and lower blood pressure.
