FOSINOPRIL SODIUM AND HYDROCHLOROTHIAZIDE vs ZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride symporter in the distal convoluted tubule of the nephron, reducing reabsorption of sodium and chloride and increasing excretion of water, sodium, chloride, potassium, and bicarbonate.
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.
10 mg orally once daily.

Clinical Note
moderateFosinoprilat: 11.5 h (terminal); Hydrochlorothiazide: 6-15 h (biphasic, terminal phase 10-15 h).
6-8 hours in normal renal function; prolonged to 20-40 hours in severe renal impairment (eGFR <30 mL/min).
Fosinopril: 45% renal, 55% biliary/fecal; Hydrochlorothiazide: >95% renal (unchanged).
Renal: 70% unchanged; Biliary/fecal: 30% (as metabolites and parent compound).
