DEAPRIL-ST vs LEXXEL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Angiotensin-converting enzyme (ACE) inhibitor. Inhibits ACE, preventing conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure.
LEXXEL is a combination of felodipine, a dihydropyridine calcium channel blocker that inhibits calcium influx into vascular smooth muscle and cardiac muscle, causing vasodilation and reduced myocardial contractility, and enalapril, an angiotensin-converting enzyme (ACE) inhibitor that prevents conversion of angiotensin I to angiotensin II, reducing vasoconstriction, aldosterone secretion, and sodium reabsorption.
Oral: 2.5 mg twice daily, titrated up to 5 mg twice daily as tolerated. Maximum dose: 10 mg daily.
1 tablet (felodipine 5 mg / enalapril 5 mg) orally once daily, may increase to 2 tablets once daily after 2-4 weeks if needed.

8-10 hours; prolonged in renal impairment (up to 24 hours in severe cases)
Enalapril: ~1.3 hours; Enalaprilat: terminal half-life ~35-38 hours, with multiple-dose accumulation half-life ~11 hours; effective half-life for ACE inhibition ~24 hours.
Renal (90% as unchanged drug), biliary/fecal (10%)
Renal: ~35-50% as unchanged drug (enalaprilat), biliary/fecal: ~15-30% as metabolites and unchanged drug; total renal elimination of enalaprilat accounts for ~60-80% of dose.
