Metabolite Identification
Common NameN-Monodemethylolopatadine
DescriptionN-Monodemethylolopatadine is a metabolite of olopatadine. Olopatadine hydrochloride is an antihistamine (as well as anticholinergic) and mast cell stabilizer, sold as a prescription eye drop (0.2% solution, Pataday, manufactured by Alcon). It is used to treat itching associated with allergic conjunctivitis. Olopatadine hydrochloride 0.1% is sold as Patanol (or Opatanol in some countries). A nasal spray formulation is sold as Patanase, which was approved by the FDA on April 15, 2008. (Wikipedia)
