Esmirtazapine (ORG-50,081) is a drug which was under development by Organon for the treatment of insomnia and vasomotor symptoms (e.g., hot flashes) associated with menopause.[2][3][4][5] Esmirtazapine is the (S)-(+)-enantiomer of mirtazapine and possesses similar overall pharmacology, including inverse agonist actions at H1 and 5-HT2 receptors and antagonist actions at α2-adrenergic receptors.[2][6] As of March 2010, Merck terminated internal clinical development program for esmirtazapine, for hot flashes and insomnia, for strategic reasons.[7]
