Background:

Olmesartan medoxomil, the medoxomil ester of olmesartan, is novel and oral antagonist of angiotensin II TYPE-1 receptor (AT₁receptor) with an inhibition constant IC₅₀of 33 nmol/L. Through oral administration, olmesartan medoxomil is rapidly absorbed by the gastrointestinal tract converting to its active metabolite olmesartan, whose inhibition constant IC₅₀towards AT₁receptor is 8 nmol/L. The esterification of olmesartan with medoxomil moiety is just to improve its water solubility (from 4.5% to 28.6%). Olmesartan medoxomil is used for the treatment of hypertension, in which olmesartan dose-dependently reduces the blood pressure through arterial vasodilation and reducing sodium retention.
