HYDROPANE vs MOEXIPRIL HYDROCHLORIDE AND HYDROCHLOROTHIAZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide diuretic; inhibits sodium chloride cotransporter in distal convoluted tubule, increasing excretion of sodium and water, and reducing plasma volume.
Moexipril is an ACE inhibitor that inhibits the conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, increasing diuresis and reducing plasma volume.
50–100 mg orally once daily, maximum 200 mg daily
One tablet (7.5 mg moexipril / 12.5 mg hydrochlorothiazide or 15 mg moexipril / 25 mg hydrochlorothiazide) orally once daily.

Terminal elimination half-life is approximately 8-15 hours in patients with normal renal function; may be prolonged in renal impairment.
Moexiprilat (active metabolite) terminal half-life is approximately 2–9 hours (mean ~9 hours in hypertension; prolonged in renal impairment). Hydrochlorothiazide terminal half-life is 6–15 hours (mean ~9 hours; prolonged in renal impairment). Clinical context: Twice-daily dosing may be needed for 24-hour BP control; renal impairment requires dose adjustment.
Renal (approximately 50% as unchanged drug) and hepatic metabolism to inactive metabolites; fecal elimination accounts for about 10%.
Moexipril is eliminated primarily by renal excretion (about 50% as unchanged drug and metabolites) and biliary/fecal excretion (about 50%). Hydrochlorothiazide is eliminated largely unchanged by renal excretion (≥95% via glomerular filtration and tubular secretion).
