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.
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.
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.
Oral, 1-4 mg once daily for hypertension; 2-4 mg once daily for heart failure.

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.
Trandolaprilat: terminal half-life ~24 hours (range 15–35 hours) for once-daily dosing; effective half-life ~6–10 hours at steady state.
Captopril: 95% renally excreted, primarily as unchanged drug and metabolites (disulfide dimers). Hydrochlorothiazide: at least 95% renally excreted as unchanged drug.
Renal: trandolapril ~33% (as trandolaprilat and metabolites), trandolaprilat ~33% (as unchanged and metabolites); biliary/fecal: ~66% of total radioactivity.
