Clozapine is an antipsychotic drug with few extra-pyramidal motor side-effects, used to treat schizophrenia which is resistant to classical neuroleptic therapy. This report shows that norclozapine but not clozapine-N-oxide has the same D2 receptor affinity as clozapine. Assay results suggest a bimodal distribution which may be explained by CYP1A2 polymorphism. Extensive metabolizers could produce other active metabolites, probably other hydroxy-clozapine derivatives.
氯氮平是一种锥体外系运动副作用较少的抗精神病药物，用于治疗对传统抗精神病药物治疗无效的精神分裂症。本报告显示，去甲氯氮平而非氯氮平 -N- 氧化物与氯氮平具有相同的 D2 受体亲和力。检测结果表明存在双峰分布，这可能由 CYP1A2 基因多态性解释。快代谢者可能会产生其他活性代谢物，可能是其他羟基氯氮平衍生物。
