HYGROTON vs MOEXIPRIL HYDROCHLORIDE AND HYDROCHLOROTHIAZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits sodium reabsorption in the distal convoluted tubule by binding to the thiazide-sensitive sodium-chloride cotransporter (NCC), leading to increased excretion of sodium, chloride, and water.
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.
25-50 mg orally once daily; may increase to 100 mg once daily for resistant hypertension or edema. 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 40-50 hours, extending up to 70 hours in patients with renal impairment, allowing for once-daily dosing.
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 50-60% as unchanged drug and metabolites); biliary/fecal elimination accounts for a minor fraction, less than 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).
