CAPOZIDE 25/25 vs MAVIK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Captopril: angiotensin-converting enzyme (ACE) inhibitor that blocks conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion. Hydrochlorothiazide: thiazide diuretic that inhibits sodium-chloride symporter in distal convoluted tubule, increasing sodium, chloride, and water excretion.
Angiotensin-converting enzyme (ACE) inhibitor; inhibits ACE, preventing conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure and reduced cardiac workload.
1 tablet (captopril 25 mg / hydrochlorothiazide 25 mg) orally once daily initially; may titrate up to 2 tablets per day as needed.
Oral, 1-4 mg once daily for hypertension; 2-4 mg once daily for heart failure.

Captopril: ~2 hours (increased in renal impairment). Hydrochlorothiazide: 6-15 hours (prolonged in renal impairment). Clinical context: trough effect may diminish with once-daily dosing; twice-daily dosing often used.
Trandolaprilat: terminal half-life ~24 hours (range 15–35 hours) for once-daily dosing; effective half-life ~6–10 hours at steady state.
Captopril: renal 95% (40-50% unchanged), biliary/fecal <5%. Hydrochlorothiazide: renal >95% (unchanged), biliary/fecal minimal.
Renal: trandolapril ~33% (as trandolaprilat and metabolites), trandolaprilat ~33% (as unchanged and metabolites); biliary/fecal: ~66% of total radioactivity.
