LIVOSTIN vs ZERVIATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Levocabastine is a selective histamine H1-receptor antagonist, inhibiting histamine release from mast cells and basophils.
ZERVIATE (cetirizine ophthalmic solution) contains cetirizine, a selective histamine H1 receptor antagonist. It inhibits histamine-induced vasodilation and increased vascular permeability, leading to reduction of ocular itching associated with allergic conjunctivitis.
1 drop (0.05% ophthalmic solution) in affected eye twice daily, up to 4 times daily if needed.
1 drop in each affected eye twice daily (approximately 8 hours apart).

Terminal elimination half-life in adults: 35-40 hours; clinical context: supports once-daily dosing, with steady-state reached after approximately 7 days
Terminal elimination half-life is approximately 3 hours; clinical context: supports twice-daily topical ocular dosing for allergic conjunctivitis.
Renal excretion as unchanged drug and metabolites: ~70% (48% unchanged, 9% as levocabastine glucuronide, 13% as other metabolites); fecal excretion: ~20%
Primarily renal excretion of unchanged drug (approximately 70%) and metabolites; biliary/fecal elimination accounts for less than 20%.
