CAPTOPRIL vs VASOTEC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive inhibitor of angiotensin-converting enzyme (ACE), preventing conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion.
Enalaprilat, the active metabolite of enalapril, competitively inhibits angiotensin-converting enzyme (ACE), preventing conversion of angiotensin I to angiotensin II. This reduces vasoconstriction, aldosterone secretion, and sodium reabsorption, leading to decreased blood pressure and afterload.
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.
2.5 to 10 mg orally twice daily; initial dose 5 mg once daily; titrate based on blood pressure response; maximum 40 mg/day.

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
Terminal half-life 1.9 hours, prolonged to 3.5-32 hours in renal impairment; clinical context: requires adjusted dosing in renal failure
Terminal half-life of enalaprilat is 35-38 hours, with multiple-dose half-life ~11 hours due to prolonged terminal phase; clinical context: once-daily dosing achieves steady-state in 3-4 days.
Primarily renal (50-60% unchanged), with minor biliary/fecal elimination (<5%)
Renal: 60-70% as enalaprilat; fecal: 20-30% as enalaprilat; biliary: minor (<10%).
