Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzthiazide is a thiazide diuretic that inhibits the sodium-chloride symporter in the distal convoluted tubule, increasing excretion of sodium, chloride, and water.
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.
25-100 mg orally once daily in the morning.
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.

Terminal elimination half-life: 2-3 hours (prolonged in renal impairment, e.g., up to 24 hours in anuria)
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).
Renal: ~95% as unchanged drug; biliary/fecal: ~5%
Lisinopril is excreted unchanged in urine; 100% renal elimination. Hydrochlorothiazide is excreted primarily by the kidney (≥95% as unchanged drug) via tubular secretion.
