CHILDREN'S FEXOFENADINE HYDROCHLORIDE HIVES vs LIVOSTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fexofenadine is a peripheral H1-receptor antagonist that selectively inhibits histamine-mediated effects on H1 receptors, reducing allergic symptoms. It does not penetrate the blood-brain barrier significantly, minimizing sedation.
Levocabastine is a selective histamine H1-receptor antagonist, inhibiting histamine release from mast cells and basophils.
Adults and children 12 years and older: 180 mg orally once daily or 60 mg orally twice daily.
1 drop (0.05% ophthalmic solution) in affected eye twice daily, up to 4 times daily if needed.

Terminal elimination half-life is approximately 14.4 hours (range 11–15 hours) in healthy adults. This supports once-daily dosing. Half-life may be prolonged in patients with renal impairment (up to 19 hours).
Terminal elimination half-life in adults: 35-40 hours; clinical context: supports once-daily dosing, with steady-state reached after approximately 7 days
Fexofenadine is primarily excreted unchanged in feces (approximately 80%) via biliary elimination, with minimal renal excretion (approximately 11%). It is not metabolized by the liver.
Renal excretion as unchanged drug and metabolites: ~70% (48% unchanged, 9% as levocabastine glucuronide, 13% as other metabolites); fecal excretion: ~20%
