Angiotensin II blocker; displaces angiotensin II from AT1 receptor and may lower blood pressure by antagonizing AT1-induced vasoconstriction, aldosterone release, catecholamine release, arginine vasopressin release, water absorption, and hypertrophic responses.
May induce more complete inhibition of renin-angiotensin system compared with ACE inhibitors; does not affect response to bradykinin.
Inhibits the pressor effects of an angiotensin II infusion in a dose-related manner.
