DIUCARDIN vs MOEXIPRIL HYDROCHLORIDE AND HYDROCHLOROTHIAZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide diuretic that inhibits the Na+/Cl- symporter in the distal convoluted tubule, reducing sodium and chloride reabsorption, leading to increased diuresis and vasodilation.
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.
Hydrochlorothiazide 25-50 mg orally once daily, titrated based on response. Maximum dose 100 mg/day.
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 18-24 hours in normal renal function. This prolongs significantly in renal impairment, requiring dose adjustment.
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.
Primarily renal excretion: approximately 60-70% of the dose is excreted unchanged in urine within 24 hours. Biliary/fecal elimination accounts for about 20-30%, with some enterohepatic circulation.
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).
