BENZTHIAZIDE vs FOSINOPRIL SODIUM AND HYDROCHLOROTHIAZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits sodium-chloride symporter in the distal convoluted tubule of the nephron, reducing sodium reabsorption and increasing excretion of water, sodium, chloride, potassium, and hydrogen ions. Also causes vasodilation via direct arteriolar relaxation.
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.
Adults: 25-50 mg orally once daily initially, may increase to 100 mg daily in a single dose or two divided doses. Maximum dose: 100 mg/day.
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.

Clinical Note
moderateBenzthiazide + Mecamylamine
"The risk or severity of adverse effects can be increased when Benzthiazide is combined with Mecamylamine."
Clinical Note
moderateDexketoprofen + Benzthiazide
"The risk or severity of adverse effects can be increased when Dexketoprofen is combined with Benzthiazide."
Terminal elimination half-life: 8-12 hours; clinical context: supports once-daily dosing for hypertension, but duration of action may extend beyond half-life due to tissue distribution.
Fosinoprilat: 11.5 h (terminal); Hydrochlorothiazide: 6-15 h (biphasic, terminal phase 10-15 h).
Renal: ~90% (60% unchanged, 30% as glucuronide conjugate); biliary/fecal: minimal (<5%).
Fosinopril: 45% renal, 55% biliary/fecal; Hydrochlorothiazide: >95% renal (unchanged).
