Description

Dynase 120 metered Nasal Spray

Indications
This combination nasal spray is indicated for the relief of symptoms of seasonal allergic rhinitis in patients 6 years of age and older who require treatment with both Azelastine Hydrochloride and Fluticasone Propionate for symptomatic relief.

Pharmacology
Azelastine Hydrochloride exhibits histamine H1-receptor antagonist activity in isolated tissues. The major metabolite, desmethylazelastine, also possesses H1-receptor antagonist activity. Fluticasone Propionate is a synthetic trifluorinated corticosteroid with anti-inflammatory activity. The precise mechanism through which Fluticasone Propionate affects allergic rhinitis symptoms is not known. Corticosteroids have been shown to have a wide range of effects on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, and lymphocytes etc.) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in inflammation.

Dosage
Adult: The recommended dosage is one spray each nostril twice daily.

Paediatric: The safety and effectiveness of Azelastine Hydrochloride and Fluticasone Propionate Nasal Spray has not been established for patients less than 6 years of age.
