ACCUPRIL vs PERINDOPRIL ERBUMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Angiotensin-converting enzyme (ACE) inhibitor; inhibits ACE, thereby blocking conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure.
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.
10-40 mg orally once daily; initial dose 10 mg, titrate to target dose based on blood pressure response; maximum 80 mg/day.
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.

Quinaprilat terminal elimination half-life is approximately 3 hours. In patients with renal impairment (CrCl <30 mL/min), half-life can be prolonged up to 10-25 hours, requiring dose adjustment.
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.
Primarily renal (about 60% as unchanged drug and 40% as metabolites, mainly quinaprilat), with biliary/fecal elimination accounting for less than 10%.
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.
