FOSINOPRIL SODIUM AND HYDROCHLOROTHIAZIDE vs TRICHLORMETHIAZIDE
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.
Inhibits sodium-chloride symporter in distal convoluted tubule, increasing excretion of sodium, chloride, and water.
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.
2-4 mg orally once daily; maximum 4 mg/day.

Clinical Note
moderateTrichlormethiazide + Deslanoside
"The risk or severity of adverse effects can be increased when Trichlormethiazide is combined with Deslanoside."
Clinical Note
moderateFosinoprilat: 11.5 h (terminal); Hydrochlorothiazide: 6-15 h (biphasic, terminal phase 10-15 h).
Terminal elimination half-life is approximately 2-6 hours (average 3.5 h); clinical context: short half-life necessitates once or twice daily dosing for sustained diuresis.
Fosinopril: 45% renal, 55% biliary/fecal; Hydrochlorothiazide: >95% renal (unchanged).
Primarily renal (tubular secretion); ~70% excreted unchanged in urine; minor biliary/fecal (<10% total).
