C16H17N3 (251.1422)


N-desmethylmirtazapine is a metabolite of mirtazapine. Mirtazapine (Remeron, Avanza, Zispin) is a noradrenergic and specific serotonergic antidepressant (NaSSA) which was introduced by Organon International in the United States in 1990 and is used primarily in the treatment of depression. It is also commonly used as an anxiolytic, hypnotic, antiemetic, and appetite stimulant. Structurally, mirtazapine can also be classified as a tetracyclic antidepressant (TeCA). (Wikipedia)

C17H17NO (251.131)


Didesmethyl doxepin 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)
