Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Olmesartan medoxomil is a prodrug that is hydrolyzed to olmesartan, a selective angiotensin II receptor type 1 (AT1) antagonist. It blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II, reducing blood pressure.
Valsartan is an angiotensin II receptor blocker (ARB) that selectively binds to the AT1 receptor, inhibiting angiotensin II-mediated vasoconstriction and aldosterone secretion. It also reduces blood pressure and causes vasodilation.
Initial: 20 mg orally once daily; titrate to 40 mg once daily. Maximum 40 mg/day.
160 mg orally once daily.

Terminal elimination half-life is approximately 13–15 hours after multiple dosing, supporting once-daily dosing.
Terminal half-life 10-12 hours; allows once-daily dosing; extended in severe renal impairment (up to 20 hours)
Olmesartan is excreted primarily in feces (approximately 50–65%) via biliary elimination, with about 35–50% eliminated renally in urine as unchanged drug.
Renal: 60% unchanged; Biliary/Fecal: 40% as metabolites; total clearance ~30 L/h
