MICROZIDE vs MOEXIPRIL HYDROCHLORIDE AND HYDROCHLOROTHIAZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing reabsorption of sodium and chloride, leading to increased excretion of water and electrolytes, and a decrease in blood volume and peripheral vascular resistance.
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.
12.5-25 mg orally once daily for hypertension; 25-100 mg orally once daily for edema.
One tablet (7.5 mg moexipril / 12.5 mg hydrochlorothiazide or 15 mg moexipril / 25 mg hydrochlorothiazide) orally once daily.

Terminal elimination half-life: 8-12 hours (prolonged in renal impairment; up to 30 hours in severe insufficiency).
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 (approximately 70% unchanged drug; remainder as metabolites and conjugates); minimal biliary/fecal (<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).
