CHILDREN'S CETIRIZINE HYDROCHLORIDE ALLERGY vs LIVOSTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cetirizine is a selective antagonist of peripheral histamine H1 receptors. It inhibits the H1 receptor-mediated effects of histamine, reducing symptoms such as pruritus, sneezing, rhinorrhea, and urticaria. It also decreases eosinophil chemotaxis and adhesion molecule expression.
Levocabastine is a selective histamine H1-receptor antagonist, inhibiting histamine release from mast cells and basophils.
5-10 mg orally once daily; max 10 mg/day. For children's formulation, typical adult dose applies to patients >12 years.
1 drop (0.05% ophthalmic solution) in affected eye twice daily, up to 4 times daily if needed.

Approximately 8.3 hours (range 6–10 hours) in healthy adults; prolonged in renal impairment (e.g., up to 20 hours).
Terminal elimination half-life in adults: 35-40 hours; clinical context: supports once-daily dosing, with steady-state reached after approximately 7 days
Renal: ~60% unchanged; fecal: ~10%; minor biliary elimination.
Renal excretion as unchanged drug and metabolites: ~70% (48% unchanged, 9% as levocabastine glucuronide, 13% as other metabolites); fecal excretion: ~20%
