CAPOZIDE 50/15 vs ENALAPRILAT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CAPOZIDE 50/15 combines captopril (angiotensin-converting enzyme inhibitor) and hydrochlorothiazide (thiazide diuretic). Captopril inhibits ACE, reducing angiotensin II formation, decreasing aldosterone secretion, and lowering blood pressure. Hydrochlorothiazide increases sodium and water excretion by inhibiting the Na+/Cl- cotransporter in distal convoluted tubules.
Enalaprilat is an angiotensin-converting enzyme (ACE) inhibitor that blocks the conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure and cardiac workload.
Oral, 1 tablet (captopril 50 mg / hydrochlorothiazide 15 mg) once daily. May increase to 2 tablets daily in divided doses if needed.
1.25 mg IV over 5 minutes every 6 hours; may increase to 5 mg IV every 6 hours if needed.

Clinical Note
moderateEnalaprilat + Benzydamine
"The risk or severity of adverse effects can be increased when Enalaprilat is combined with Benzydamine."
Clinical Note
moderateEnalaprilat + Estrone sulfate
"The serum concentration of Estrone sulfate can be decreased when it is combined with Enalaprilat."
Clinical Note
moderateEnalaprilat + Droxicam
"The risk or severity of adverse effects can be increased when Enalaprilat is combined with Droxicam."
Clinical Note
moderateEnalaprilat + Loxoprofen
Captopril: terminal half-life ~2 hours (in patients with normal renal function; prolonged in renal impairment to 21-36 hours). Hydrochlorothiazide: half-life 6-15 hours (mean ~9 hours; prolonged in renal impairment). Clinical context: dosing interval affected by renal function.
Terminal half-life: 35 hours (prolonged in renal impairment; accumulates with CrCl <30 mL/min)
Captopril: renal excretion of unchanged drug and metabolites, primarily in urine (60-75%), with ~20% as unchanged captopril; small amount in feces (5-10%). Hydrochlorothiazide: renal excretion (95% unchanged), <5% via biliary/fecal.
Renal: 60-80% unchanged; biliary/fecal: minimal (<10%)
