What is azelastine hydrochloride and fluticasone propionat, and how does it work (mechanism of action)?

Dymista is a prescription nasal spray used to treat symptoms of seasonal allergic rhinitis (inflammation of the lining of the nose) such as runny nose, stuffy nose, itching, and sneezing. Dymista contains two medicines, azelastine hydrochloride and fluticasone propionate, which are also available individually as nasal sprays. In Dymista, azelastine hydrochloride an antihistamine, and fluticasone propionate, a corticosteroid work in different yet complementary ways.

Azelastine hydrochloride blocks the release and actions of histamine, a chemical responsible for causing many of the symptoms of allergy. Fluticasone propionate is a corticosteroid that reduces inflammation and the body's immune response. When used together, azelastine hydrochloride and fluticasone propionate provide better relief of symptoms than either medicine alone. In clinical trials, Dymista was superior to azelastine nasal spray, fluticasone nasal spray, and placebo in providing symptom relief. Dymista was approved by the FDA in May, 2012.
