CHLOROTHIAZIDE SODIUM vs FOSINOPRIL SODIUM AND HYDROCHLOROTHIAZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits sodium-chloride symporter in distal convoluted tubule of nephron, reducing sodium reabsorption and promoting diuresis.
Fosinopril 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 the sodium-chloride symporter in the distal convoluted tubule, increasing excretion of sodium and water.
500 mg to 1 g orally or intravenously once or twice daily.
1 tablet (fosinopril 10 mg/hydrochlorothiazide 12.5 mg or fosinopril 20 mg/hydrochlorothiazide 12.5 mg) orally once daily. Maximum dose: fosinopril 80 mg/hydrochlorothiazide 50 mg per day.

Terminal elimination half-life is 45–120 minutes in patients with normal renal function; prolonged in renal impairment (up to 24 hours in anuria).
Fosinoprilat: 11.5 h (terminal); Hydrochlorothiazide: 6-15 h (biphasic, terminal phase 10-15 h).
Primarily renal excretion via tubular secretion; approximately 95% of absorbed dose excreted unchanged in urine within 24 hours, with less than 5% eliminated via bile/feces.
Fosinopril: 45% renal, 55% biliary/fecal; Hydrochlorothiazide: >95% renal (unchanged).
