DYMISTA vs LIVOSTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Azelastine is a histamine H1-receptor antagonist; fluticasone propionate is a corticosteroid with anti-inflammatory activity. The combination reduces nasal symptoms by blocking histamine receptors and inhibiting inflammatory mediators.
Levocabastine is a selective histamine H1-receptor antagonist, inhibiting histamine release from mast cells and basophils.
One spray (137 mcg azelastine hydrochloride/50 mcg fluticasone propionate) per nostril twice daily, intranasal.
1 drop (0.05% ophthalmic solution) in affected eye twice daily, up to 4 times daily if needed.

Azelastine: terminal half-life ~22 hours (plasma) with long-lasting antihistamine effect. Fluticasone propionate: terminal half-life ~7.8 hours (intravenous), but intranasal systemic exposure is very low.
Terminal elimination half-life in adults: 35-40 hours; clinical context: supports once-daily dosing, with steady-state reached after approximately 7 days
Azelastine: ~75% renal (primarily as parent and metabolites), ~25% fecal. Fluticasone propionate: <5% renal, >95% fecal as parent and metabolites.
Renal excretion as unchanged drug and metabolites: ~70% (48% unchanged, 9% as levocabastine glucuronide, 13% as other metabolites); fecal excretion: ~20%
