LIVOSTIN vs TEMARIL
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.
Temaril (trimeprazine tartrate and prednisolone) combines an antipruritic phenothiazine antihistamine with a corticosteroid. Trimeprazine blocks histamine H1 receptors, reducing pruritus and allergic reactions. Prednisolone suppresses inflammation via glucocorticoid receptor activation, inhibiting phospholipase A2 and cytokine production.
1 drop (0.05% ophthalmic solution) in affected eye twice daily, up to 4 times daily if needed.
2.5 mg orally twice daily or 5 mg orally at bedtime; maximum 10 mg/day.

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 9–12 hours in adults; prolonged in hepatic impairment (up to 20 hours). Given TID dosing, steady state is reached within 2 days.
Renal excretion as unchanged drug and metabolites: ~70% (48% unchanged, 9% as levocabastine glucuronide, 13% as other metabolites); fecal excretion: ~20%
Primarily via kidneys as metabolites; unchanged drug accounts for <1%. Biliary/fecal excretion is minor. Approx. 90% recovered in urine within 24 hours.
