MONOPRIL-HCT vs ZESTORETIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fosinopril is an angiotensin-converting enzyme (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 electrolyte and water excretion.
Combination of lisinopril (ACE inhibitor) and hydrochlorothiazide (thiazide diuretic). Lisinopril inhibits angiotensin-converting enzyme, reducing angiotensin II formation, decreasing vasoconstriction and aldosterone secretion. Hydrochlorothiazide inhibits sodium reabsorption in distal convoluted tubule, increasing diuresis and reducing plasma volume.
1 tablet (10-20 mg fosinopril / 12.5-25 mg hydrochlorothiazide) orally once daily; maximum dose 80 mg fosinopril / 50 mg hydrochlorothiazide per day.
Zestoretic (lisinopril/hydrochlorothiazide) is available in fixed-dose combinations. Typical adult dose: 10 mg/12.5 mg, 20 mg/12.5 mg, or 20 mg/25 mg orally once daily. Maximum dose: lisinopril 80 mg/day, hydrochlorothiazide 50 mg/day.

Fosinoprilat: 11.5-12 h (terminal half-life extended in renal and hepatic impairment); hydrochlorothiazide: 5.6-14.8 h (varies with renal function).
Lisinopril: terminal half-life approximately 12 hours (accumulation half-life 13.8 hours in patients with normal renal function). Hydrochlorothiazide: terminal half-life 5.6–14.8 hours (mean 9.6 hours).
Fosinopril: renal (44%), biliary (46%); hydrochlorothiazide: renal (>95% as unchanged drug).
Lisinopril is excreted unchanged in urine; 100% renal elimination. Hydrochlorothiazide is excreted primarily by the kidney (≥95% as unchanged drug) via tubular secretion.
