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)
