Metabolite Identification
Common NameClozapine N-oxide
DescriptionClozapine N-oxide is a metabolite of clozapine. Clozapine (sold as Clozaril, Gen-Clozapine in Canada, Azaleptin, Leponex, Fazaclo, Froidir; Denzapine, Zaponex in the UK; Klozapol in Poland, Clopine in Australia and New Zealand) is an atypical antipsychotic medication used in the treatment of schizophrenia, and is also used off-label in the treatment of bipolar disorder.
