Metabolite Identification
Common Name5-Hydroxyemedastine
Description5-Hydroxyemedastine belongs to the class of organic compounds known as benzimidazoles. These are organic compounds containing a benzene ring fused to an imidazole ring (five member ring containing a nitrogen atom, 4 carbon atoms, and two double bonds). 5-Hydroxyemedastine is a very strong basic compound (based on its pKa). It's mechanism of action is a H1 receptor antagonist. Emedastine difumarate (Emadine) is a second generation antihistamine used in eye drops to treat allergic conjunctivitis. 5-Hydroxyemedastine is a metabolite of emedastine.
