Zopiclone N-oxide
Zopiclone N-oxide is a primary, active metabolite of zopiclone. Zopiclone (brand names Imovane, Zimovane, and Dopareel) is a nonbenzodiazepine hypnotic agent used in the treatment of insomnia. Zopiclone is molecularly distinct from benzodiazepine drugs and belongs to the class of drugs known as cyclopyrrolones. However, zopiclone increases the normal transmission of the neurotransmitter gamma-aminobutyric acid (GABA) in the central nervous system, via modulating benzodiazepine receptors in the same way that benzodiazepine drugs do (Wikipedia).
