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.
Phenetron is an antihistamine that competes with histamine for H1-receptor sites, blocking histamine-mediated effects in the respiratory tract, vascular system, and gastrointestinal tract. It also exhibits anticholinergic and sedative properties.
1 drop (0.05% ophthalmic solution) in affected eye twice daily, up to 4 times daily if needed.
Adults: 50 mg intramuscularly every 6 hours 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
Terminal half-life 12–15 hours; clinically, steady-state achieved in ~3 days
Renal excretion as unchanged drug and metabolites: ~70% (48% unchanged, 9% as levocabastine glucuronide, 13% as other metabolites); fecal excretion: ~20%
Renal: ~70% unchanged; Biliary/Fecal: ~15% as metabolites; 15% unidentified
