CAPOZIDE 50/25 vs CAPTOPRIL
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, reducing vasoconstriction and aldosterone secretion. Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride symporter in the distal convoluted tubule, increasing excretion of sodium and water.
Competitive inhibitor of angiotensin-converting enzyme (ACE), preventing conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion.
One tablet (captopril 50 mg / hydrochlorothiazide 25 mg) orally once daily; may increase to two tablets daily if needed.
Initial: 25 mg PO 2-3 times daily; target dose: 50 mg PO 2-3 times daily; maximum: 450 mg/day. For heart failure: start 6.25-12.5 mg PO 3 times daily, titrate to 25-50 mg PO 3 times daily.

Clinical Note
moderateCaptopril + Benzydamine
"The risk or severity of adverse effects can be increased when Captopril is combined with Benzydamine."
Clinical Note
moderateCaptopril + Estrone sulfate
"The serum concentration of Estrone sulfate can be decreased when it is combined with Captopril."
Clinical Note
moderateCaptopril + Droxicam
"The risk or severity of adverse effects can be increased when Captopril is combined with Droxicam."
Clinical Note
moderateCaptopril + Loxoprofen
Captopril: ~2 hours (increased in renal impairment). Hydrochlorothiazide: 6-15 hours (prolonged in renal impairment). Clinical context: dosing interval typically 12-24 hours.
Terminal half-life 1.9 hours, prolonged to 3.5-32 hours in renal impairment; clinical context: requires adjusted dosing in renal failure
Captopril: 95% renal (primarily unchanged). Hydrochlorothiazide: 95% renal (unchanged).
Primarily renal (50-60% unchanged), with minor biliary/fecal elimination (<5%)
