Respiratory Approved 2012-05-01

Dymista is a fixed-dose combination nasal spray containing azelastine hydrochloride, an H1-receptor antagonist, and fluticasone propionate, a corticosteroid. It is indicated for the relief of symptoms associated with seasonal allergic rhinitis in adults and pediatric patients 6 years of age and older.

How DYMISTA Works

Dymista exhibits the combined pharmacological activity of its two components. Azelastine hydrochloride is a histamine H1-receptor antagonist that inhibits the immediate hypersensitivity reaction. Fluticasone propionate is a synthetic trifluorinated corticosteroid with potent anti-inflammatory activity. It acts on multiple cell types and mediators involved in the allergic response, demonstrating significantly higher affinity for the glucocorticoid receptor than dexamethasone.
