ENALAPRILAT vs PRINZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
PRINZIDE is a combination of lisinopril (an ACE inhibitor) and hydrochlorothiazide (a thiazide diuretic). Lisinopril inhibits angiotensin-converting enzyme, reducing angiotensin II formation, leading to vasodilation and decreased aldosterone secretion. Hydrochlorothiazide inhibits sodium and chloride reabsorption in the distal convoluted tubule, promoting diuresis and reducing plasma volume.
1.25 mg IV over 5 minutes every 6 hours; may increase to 5 mg IV every 6 hours if needed.
Oral, 1-2 tablets daily; each tablet contains 25 mg hydrochlorothiazide and 5 mg lisinopril. Adjust based on blood pressure response; maximum daily dose: 2 tablets.

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
Terminal half-life: 35 hours (prolonged in renal impairment; accumulates with CrCl <30 mL/min)
Lisinopril: terminal half-life 12 hours (effective half-life 30 hours due to prolonged ACE binding). Hydrochlorothiazide: terminal half-life 6-15 hours (biphasic, initial phase 2-4 h, terminal phase 6-15 h) with prolonged terminal phase in renal impairment.
Renal: 60-80% unchanged; biliary/fecal: minimal (<10%)
Lisinopril is excreted unchanged in urine (100% renal elimination); hydrochlorothiazide is excreted 95% renally as unchanged drug and 5% via bile.
