LEXXEL vs UNIVASC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Angiotensin-converting enzyme (ACE) inhibitor; inhibits conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure.
1 tablet (felodipine 5 mg / enalapril 5 mg) orally once daily, may increase to 2 tablets once daily after 2-4 weeks if needed.
Initial: 7.5 mg orally once daily; titrate to 15-30 mg once daily. Maximum: 60 mg/day.

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.
The terminal elimination half-life of moexiprilat, the active metabolite, is approximately 9.8 hours in patients with normal renal function. This supports once-daily dosing, though the antihypertensive effect may persist beyond 24 hours with continued therapy.
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.
Univasc (moexipril) is primarily eliminated via renal excretion (approximately 50% of absorbed dose as unchanged drug and metabolites) and fecal excretion (about 50%).
