CAPOZIDE 50/15 vs LISINOPRIL
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.
Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor. It inhibits ACE, which converts angiotensin I to angiotensin II, a potent vasoconstrictor. This results in decreased plasma angiotensin II, leading to decreased vasoconstriction, reduced aldosterone secretion, decreased sodium and water retention, and lower blood pressure.
Oral, 1 tablet (captopril 50 mg / hydrochlorothiazide 15 mg) once daily. May increase to 2 tablets daily in divided doses if needed.
Initial: 5-10 mg orally once daily. Maintenance: 10-40 mg orally once daily. Max: 80 mg/day.

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.
Terminal half-life approximately 12 hours (range 11–13 hours); clinical context: once-daily dosing for hypertension and heart failure; accumulation occurs with renal impairment.
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.
Renal: 100% unchanged via glomerular filtration and tubular secretion; negligible biliary/fecal elimination.
