Metabolite Identification
Common Name(E)-2-Hydroxy-N-desmethyldoxepin
Description(E)-2-Hydroxy-N-desmethyldoxepin is a metabolite of doxepin. Doxepin is a psychotropic agent with tricyclic antidepressant and anxiolytic properties, known under many brand-names such as Aponal, the original preparation by Boehringer-Mannheim, now part of the Roche group; Adapine, Doxal, Deptran, Sinquan and Sinequan. As doxepin hydrochloride, it is the active ingredient in cream-based preparations (Zonalon and Xepin) for the treatment of dermatological itch. (Wikipedia)
