KARBINAL ER vs LIVOSTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Carbinoxamine is a first-generation antihistamine with anticholinergic and sedative properties. It competitively antagonizes histamine at H1 receptor sites, thereby alleviating symptoms of allergic reactions.
Levocabastine is a selective histamine H1-receptor antagonist, inhibiting histamine release from mast cells and basophils.
Adults: 1-2 tablets (6-12 mg carbinoxamine) orally every 4-6 hours as needed; maximum 24 mg/day.
1 drop (0.05% ophthalmic solution) in affected eye twice daily, up to 4 times daily if needed.

Terminal elimination half-life ranges from 20 to 30 hours, supporting once-daily dosing in extended-release formulation.
Terminal elimination half-life in adults: 35-40 hours; clinical context: supports once-daily dosing, with steady-state reached after approximately 7 days
Renal (approximately 50% as unchanged drug and metabolites); fecal (approximately 40%); biliary (minor).
Renal excretion as unchanged drug and metabolites: ~70% (48% unchanged, 9% as levocabastine glucuronide, 13% as other metabolites); fecal excretion: ~20%
