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.
Angiotensin-converting enzyme (ACE) inhibitor; inhibits conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure.
Initial dose 10 mg orally once daily; titrate to target dose of 20-40 mg daily based on blood pressure response.
Initial: 7.5 mg orally once daily; titrate to 15-30 mg once daily. Maximum: 60 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.
The terminal elimination half-life of moexiprilat, the active metabolite, is approximately 9.8 hours in patients with normal renal function. This supports once-daily dosing, though the antihypertensive effect may persist beyond 24 hours with continued therapy.
Renal excretion accounts for approximately 60% of total clearance, primarily as unchanged lisinopril; fecal excretion accounts for negligible amounts.
Univasc (moexipril) is primarily eliminated via renal excretion (approximately 50% of absorbed dose as unchanged drug and metabolites) and fecal excretion (about 50%).
