摘要: 目的 建立反相高效液相色谱法测定精神分裂症患者富马酸喹硫平血浓度的方法学,探讨其血浓度与患者年龄、性别、服药剂量及临床疗效的关系。方法 采用高效液相色谱法测定76 例单一服用富马酸喹硫平的精神分裂症住院患者治疗前及治疗后第2 、4 、6 wk 肘静脉血浓度,并进行BPRS 量表评定及相关性分析。结果 富马酸喹硫平血浓度在0 .05 ~ 0 .5 mg·L-1范围内有良好线性关系(r=0 .9850)。日剂量50 ~ 450 mg 时血浓度随剂量增大而升高,但与服药患者年龄、性别无显著相关性。血浓度在0 .126 ~ 0 .350 mg·L-1范围内临床效果较好。结论 测定方法简便、准确、专一性强,可用于富马酸喹硫平治疗药物监测。治疗窗浓度为0 .126 ~0 .350 mg·L-1

Abstract: AIM: To establish a method for determination of serum concentrations of quetiapine fumarate inPatients with schizophrenia of different doses and to study its relationshiPwith clinical response.METHODS: A HPLC method was used to determine serum concentrations of quetiapine fumarate in 76Patients with schizophrenia before or after 2,4,6-week treatment and its therapeutic efficacies were measured by BPRS.RESULTS: The standard curve waslinearwithin the concentration range of 0.05 -0.5 mg·L-1of quetiapine fumarate in serum(r=0.9850).The serum concentrations of quetiapine fumarate wereProportionally increased with the daily dose of 50 -450 mg,but there was no significant correlation with age and sex.The optimal range estimated was 0.126 -0.350 mg·L-1.CONCLUSION: The assay is simple,precise and suitable for therapeutic monitoring of quetiapine fumarate and the optimal concentration window is 0.126 -0.350 mg·L-1in treatment ofPatients with schizophrenia.
