ACCURETIC vs PRESTALIA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ACCURETIC is a combination of quinapril, an angiotensin-converting enzyme (ACE) inhibitor, and hydrochlorothiazide, a thiazide diuretic. Quinapril inhibits ACE, preventing conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion. Hydrochlorothiazide inhibits sodium reabsorption in the distal convoluted tubule, increasing diuresis and lowering blood pressure.
PRESTALIA is a fixed-dose combination of perindopril, an angiotensin-converting enzyme inhibitor, and amlodipine, a dihydropyridine calcium channel blocker. Perindopril inhibits ACE, reducing angiotensin II formation, leading to vasodilation and decreased aldosterone secretion. Amlodipine inhibits calcium ion influx across cardiac and vascular smooth muscle cell membranes, causing vasodilation and reduced peripheral resistance.
One tablet orally once daily. Initial dose is 20 mg quinapril/12.5 mg hydrochlorothiazide, titrated to maximum 20 mg quinapril/25 mg hydrochlorothiazide.
One tablet orally once daily, preferably in the morning. PRESTALIA is a fixed-dose combination of perindopril arginine (2.5 mg, 5 mg, or 10 mg) and amlodipine (5 mg or 10 mg). Initial dose: 3.5 mg perindopril arginine/2.5 mg amlodipine or 5 mg perindopril arginine/5 mg amlodipine. Titrate based on blood pressure response. Maximum dose: 10 mg perindopril arginine/10 mg amlodipine.

Quinapril: 0.8 hours; Quinaprilat (active): 2 hours in young healthy adults, prolonged to 3-4 hours in elderly or renal impairment.
Perindoprilat: 30–120 hours (terminal, prolonged in renal impairment; effective half-life for accumulation ~24h). Indapamide: 14–24 hours (terminal).
Renal: approximately 90% (60% unchanged, 30% as metabolites). Fecal/biliary: <10%.
Perindopril: 75% renal (as perindoprilat), 25% biliary/fecal. Indapamide: 70% renal, 20% biliary/fecal.
