CAPOZIDE 25/15 vs LISINOPRIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of captopril (ACE inhibitor) and hydrochlorothiazide (thiazide diuretic). Captopril inhibits angiotensin-converting enzyme, reducing angiotensin II formation, decreasing vasoconstriction and aldosterone secretion. Hydrochlorothiazide inhibits sodium reabsorption in the distal convoluted tubule, increasing diuresis and reducing plasma volume.
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 25 mg / hydrochlorothiazide 15 mg) once daily initially; titrate to a maximum of 2 tablets twice daily based on blood pressure response.
Initial: 5-10 mg orally once daily. Maintenance: 10-40 mg orally once daily. Max: 80 mg/day.

Clinical Note
moderateLisinopril + Estrone sulfate
Captopril: ~2 hours (terminal) in normal renal function; increases to 20-60 hours in severe renal impairment. Hydrochlorothiazide: 6-15 hours (terminal), prolonged in renal impairment.
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: 95% renally excreted, primarily as unchanged drug and metabolites (disulfide dimers). Hydrochlorothiazide: at least 95% renally excreted as unchanged drug.
Renal: 100% unchanged via glomerular filtration and tubular secretion; negligible biliary/fecal elimination.
