Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of an angiotensin II receptor blocker (ARB) and a thiazide diuretic. Olmesartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively antagonizing the AT1 receptor. Hydrochlorothiazide inhibits the sodium-chloride symporter in the distal convoluted tubule, increasing excretion of sodium, chloride, and water, thereby reducing plasma volume.
Thiazide diuretic that inhibits the sodium-chloride symporter in the distal convoluted tubule, reducing sodium and chloride reabsorption, leading to increased diuresis and vasodilation.
One tablet orally once daily. Available strengths: 40 mg olmesartan / 12.5 mg hydrochlorothiazide, 40 mg olmesartan / 25 mg hydrochlorothiazide. Dose may be titrated after 2-4 weeks based on response.
Initial 2.5-5 mg orally once daily; increase by 2.5-5 mg every 2-4 weeks up to 20 mg/day as needed.

Olmesartan: Terminal elimination half-life is 10-15 hours, supporting once-daily dosing. Hydrochlorothiazide: Terminal half-life is 5.6-14.8 hours (mean ~10 hours), prolonged in renal impairment.
13–15 hours; prolonged in renal impairment (CrCl <30 mL/min: up to 30–40 hours).
Olmesartan: Approximately 50-65% of absorbed dose excreted in urine (10-20% as unchanged drug, remainder as metabolites), 35-50% in feces via biliary excretion. Hydrochlorothiazide: ≥95% excreted renally as unchanged drug.
Renal: ~85% unchanged; fecal: ~15% (via bile).
