MOEXIPRIL HYDROCHLORIDE AND HYDROCHLOROTHIAZIDE vs TRICHLOREX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Trichlorex is a thiazide-like diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing sodium and chloride reabsorption and increasing water excretion.
One tablet (7.5 mg moexipril / 12.5 mg hydrochlorothiazide or 15 mg moexipril / 25 mg hydrochlorothiazide) orally once daily.
Oral: 500 mg once daily after the evening meal; sustained-release: 500 mg once daily at bedtime.

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.
Terminal elimination half-life is 8-12 hours in adults; prolonged to 20-30 hours in severe renal impairment (creatinine clearance <30 mL/min).
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).
Renal (90% as unchanged drug, 10% as trichloroacetic acid and trichloroethanol); minor biliary/fecal (less than 1%).
