CAPOZIDE 50/15 vs PRESTALIA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CAPOZIDE 50/15 combines captopril (angiotensin-converting enzyme inhibitor) and hydrochlorothiazide (thiazide diuretic). Captopril inhibits ACE, reducing angiotensin II formation, decreasing aldosterone secretion, and lowering blood pressure. Hydrochlorothiazide increases sodium and water excretion by inhibiting the Na+/Cl- cotransporter in distal convoluted tubules.
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.
Oral, 1 tablet (captopril 50 mg / hydrochlorothiazide 15 mg) once daily. May increase to 2 tablets daily in divided doses if needed.
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.

Captopril: terminal half-life ~2 hours (in patients with normal renal function; prolonged in renal impairment to 21-36 hours). Hydrochlorothiazide: half-life 6-15 hours (mean ~9 hours; prolonged in renal impairment). Clinical context: dosing interval affected by renal function.
Perindoprilat: 30–120 hours (terminal, prolonged in renal impairment; effective half-life for accumulation ~24h). Indapamide: 14–24 hours (terminal).
Captopril: renal excretion of unchanged drug and metabolites, primarily in urine (60-75%), with ~20% as unchanged captopril; small amount in feces (5-10%). Hydrochlorothiazide: renal excretion (95% unchanged), <5% via biliary/fecal.
Perindopril: 75% renal (as perindoprilat), 25% biliary/fecal. Indapamide: 70% renal, 20% biliary/fecal.
