CAPTOPRIL AND HYDROCHLOROTHIAZIDE vs NATURETIN-10
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Captopril is an angiotensin-converting enzyme (ACE) inhibitor that inhibits the conversion of angiotensin I to angiotensin II, resulting in vasodilation and decreased aldosterone secretion. Hydrochlorothiazide is a thiazide diuretic that inhibits the Na+/Cl- cotransporter in the distal convoluted tubule, increasing excretion of sodium and water.
Bendroflumethiazide is a thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, increasing excretion of sodium, chloride, and water. It also reduces peripheral vascular resistance and has antihypertensive effects.
1 tablet (captopril 25 mg / hydrochlorothiazide 15 mg) orally once daily, titrated up to a maximum of 1 tablet (captopril 50 mg / hydrochlorothiazide 25 mg) twice daily.
Adults: 10 mg orally once daily.

Captopril: ~2 hours (prolonged to 6-8 hours in heart failure or renal impairment). Hydrochlorothiazide: 5.6-14.8 hours (mean ~9.6 hours; prolonged in renal impairment).
Terminal elimination half-life is approximately 2-4 hours; clinical context: dose adjustments may be needed in renal impairment.
Captopril: renal (95%), primarily as unchanged drug and disulfide metabolites. Hydrochlorothiazide: renal (≥95%) as unchanged drug via tubular secretion.
Primarily renal (approximately 50-70% as unchanged drug); biliary/fecal elimination accounts for the remainder (30-50%).
