英文摘要:

Background: Quetiapine is an atypical antipsychotic agent for the treatment of schizophrenia, acute mania, and acute bipolar depression. The antidepressive response is considered to be mediated by the metabolite norquetiapine (N-desalkylquetiapine), and the aim of this study was to develop an LC-MS/MS method to measure concentrations of these compounds in human plasma.

Methods: Following one step liquid-liquid extraction, the analytes were separated using an isocratic mobile phase on a Sunfire C18 column (50 mm x 2.1 mm, 5 pm). The retention times were 2.12, 224, 2.12 and 2.19 mm for quetiapine, norquetiapine and their respective stable labeled internal standards, respectively. Cycle time was 4 min.Selected reaction monitoring (SRM) in positive ion mode was used for quantitation. Results: The present method exhibited a linear dynamic range of 0.5-500 ng/ml for quetiapine and 0.6-600 ng/ml for norquetiapine. The applicable range was extended by dilution up to 5-fold with blank matrix. The accuracy and precision for quetiapine were <103.0% and 8.8%, for norquetiapine were <108.8% and 11.1%, respectively.

Conclusions: A rapid, sensitive, and robust LC-MS/MS method for quantifying quetiapine and its metabolite norquetiapine levels in human plasma was validated and successfully applied to samples from schizophrenic patients in clinical pharmacokinetics studies.
