LISINOPRIL AND HYDROCHLOROTHIAZIDE vs PRINIVIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lisinopril is an ACE inhibitor that prevents conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium reabsorption in the distal convoluted tubule, increasing diuresis and lowering blood pressure.
Lisinopril is an angiotensin-converting enzyme inhibitor that decreases angiotensin II production, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure.
Initial dose: 10 mg/12.5 mg orally once daily. Titrate based on blood pressure response; maximum 40 mg/25 mg per day.
Initial dose 10 mg orally once daily; titrate to target dose of 20-40 mg daily based on blood pressure response.

Lisinopril: terminal half-life 12 hours, effective half-life ~30 hours due to prolonged ACE inhibition. Hydrochlorothiazide: terminal half-life 5.6-14.8 hours (mean 9.6 hours) in patients with normal renal function.
Terminal elimination half-life is approximately 12 hours, with accumulation noted in renal impairment; effective half-life at steady state extends to 30-50 hours in patients with creatinine clearance <30 mL/min.
Lisinopril: primarily renal (100% unchanged in urine). Hydrochlorothiazide: renal (≥95% unchanged via tubular secretion).
Renal excretion accounts for approximately 60% of total clearance, primarily as unchanged lisinopril; fecal excretion accounts for negligible amounts.
