LIVOSTIN vs TRINALIN
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.
TRINALIN is a combination of azatadine, a first-generation antihistamine that antagonizes histamine H1 receptors, and pseudoephedrine, a sympathomimetic amine that stimulates alpha-adrenergic receptors, causing vasoconstriction and reducing nasal congestion.
1 drop (0.05% ophthalmic solution) in affected eye twice daily, up to 4 times daily if needed.
One tablet (azatadine 1 mg/pseudoephedrine 120 mg) orally every 12 hours. Not to exceed 2 tablets in 24 hours.

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 approximately 20-30 hours; clinical context: allows twice-daily dosing for sustained decongestant effect
Renal excretion as unchanged drug and metabolites: ~70% (48% unchanged, 9% as levocabastine glucuronide, 13% as other metabolites); fecal excretion: ~20%
Renal: 70-80% as unchanged drug and metabolites; biliary/fecal: 20-30%
