Active Ingredient History

  • Now
Azelastine, a phthalazine derivative, is an antihistamine and mast cell stabilizer. Azelastine is oxidatively metabolized to the principal active metabolite, desmethylazelastine, by the cytochrome P450 enzyme system. It is indicated for the relief of the symptoms of seasonal allergic rhinitis and perennial allergic rhinitis. The most common adverse reactions are: pyrexia, dysgeusia, nasal discomfort, epistaxis, headache, sneezing, fatigue, somnolence, upper respiratory infection, cough, rhinalgia, vomiting, otitis media, contact dermatitis, and oropharyngeal pain. Concurrent use of Azelastine with alcohol or other central nervous system depressants should be avoided because reductions in alertness and impairment of central nervous system performance may occur.   NCATS
