Metabolite Identification
Common NameAzelastine
DescriptionAzelastine is only found in individuals that have used or taken this drug. It is a phthalazine derivative, and is an antihistamine and mast cell stabilizer available as a nasal spray for hay fever and as eye drops for allergic conjunctivitis.Azelastine competes with histamine for the H1-receptor sites on effector cells and acts as an antagonist by inhibiting the release of histamine and other mediators involved in the allergic response.
