Mechanism
Olmesartan medoxomil is an angiotensin-II receptor antagonist (ARB) that potently and selectively inhibits the biological effects of Angiotensin-II. It blocks the actions of Angiotensin-II via the AT1 receptor, irrespective of the biochemical pathway leading to Angiotensin-II formation. This action reduces Angiotensin-II induced vasoconstriction, aldosterone secretion, thirst, vasopressin release, and cellular hypertrophy, thereby decreasing arterial blood pressure.
