Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Perindopril is a prodrug that is hydrolyzed to perindoprilat, a competitive inhibitor of angiotensin-converting enzyme (ACE). It blocks the conversion of angiotensin I to angiotensin II, reducing vasoconstriction, aldosterone secretion, and catecholamine release, 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.
2.5–10 mg orally once daily; initial dose 2.5 mg for hypertension, 4 mg for stable coronary artery disease; titrate based on response.
10 mg orally once daily initially; titrate to 20-40 mg orally once daily. Maximum 80 mg/day.

The terminal elimination half-life of perindopril is 1.5–3 hours, but for the active metabolite perindoprilat it is 30–120 hours, due to slow dissociation from tissue ACE. This long half-life supports once-daily dosing for 24-hour blood pressure control.
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.
Perindopril is extensively metabolized to perindoprilat. Approximately 75% of an oral dose is excreted in urine (as perindoprilat and metabolites) and 25% in feces (mainly as perindoprilat). Less than 5% is excreted unchanged in urine. Biliary excretion is minimal.
Primarily renal (approximately 70% unchanged), with the remainder excreted as inactive metabolites via feces and urine.
