Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lisinopril is an angiotensin-converting enzyme inhibitor that decreases angiotensin II production, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure.
Lisinopril competes with angiotensin I for binding to angiotensin-converting enzyme (ACE), inhibiting its activity, thereby preventing conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. This leads to decreased blood pressure, reduced aldosterone secretion, and decreased sodium and water retention.
Initial dose 10 mg orally once daily; titrate to target dose of 20-40 mg daily based on blood pressure response.
10 mg orally once daily initially; titrate to 20-40 mg orally once daily. Maximum 80 mg/day.

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.
Terminal elimination half-life is about 12 hours for lisinopril; in heart failure, half-life may be prolonged. Steady-state achieved in 2-3 days.
Renal excretion accounts for approximately 60% of total clearance, primarily as unchanged lisinopril; fecal excretion accounts for negligible amounts.
Primarily renal (approximately 70% unchanged), with the remainder excreted as inactive metabolites via feces and urine.
