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.
Selective histamine H1-receptor antagonist. Inhibits histamine-mediated vasodilation, capillary permeability, and smooth muscle contraction.
1 drop (0.05% ophthalmic solution) in affected eye twice daily, up to 4 times daily if needed.
For chronic idiopathic urticaria, adults: 10 mg orally once daily. For intermittent symptoms, up to 10 mg once daily as needed.

Terminal elimination half-life in adults: 35-40 hours; clinical context: supports once-daily dosing, with steady-state reached after approximately 7 days
The terminal elimination half-life is approximately 8.3 hours in healthy adults. In patients with renal impairment (CrCl < 40 mL/min), half-life can extend to 18–21 hours, necessitating dose adjustment.
Renal excretion as unchanged drug and metabolites: ~70% (48% unchanged, 9% as levocabastine glucuronide, 13% as other metabolites); fecal excretion: ~20%
Cetirizine is primarily excreted renally as unchanged drug (approximately 70%). Fecal excretion accounts for about 10%. The remainder undergoes hepatic metabolism to inactive metabolites, which are also renally eliminated.
