摘要: 目的 探讨奥氮平血药达峰浓度(Cmax)与个体内在因素的相关性。方法 采用LC-MS/MS测定20名健康志愿者奥氮平的Cmax,采用偏最小二乘回归方法(PLS)分析Cmax与个体内在因素包括年龄、体重指数(BMI)、白细胞(WBC)、红细胞(RBC)、血小板(PLT)、血红蛋白(HB)、肌酐(Cr)、尿素氮(BUN)、总蛋白(TP)、白蛋白(ALB)、碱性磷酸酶(AKP)、谷丙转氨酶(ALT)等的相关性。结果 通过PLS分析结果表明:Cmax与BMI、WBC 、BUN、TP、ALT 呈正相关;与RBC、PLT、HB、Cr、ALB、AKP呈负相关,其中与BMI、WBC、RBC、BUN、TP相关性最强。预测建模分析显示,模型拟合效果较好,可以作为预测奥氮平体内Cmax的参考指标。结论 个体内在因素影响奥氮平的Cmax,可以为临床个体化用药提供参考。

Abstract: AIM: To evaluate the relationship between olanzapine plasma concentrations and individual intrinsic factors. METHODS: The concentrations of olanzapine in plasma were determined by LC-MS/MS method. The PLS model was used to analysis the correlation between AGE, BMI, WBC, RBC, PLT, HB, Cr, BUN,TP, ALB,AKP, ALT and Cmax. RESULTS: Positive correlations between Cmax and BMI, WBC, BUN, TP, ALT and negative correlation between Cmax and RBC, PLT, HB, Cr, ALB, AKP were observed. Among the total, significant correlations were observed with BMI,WBC,RBC,BUN,TP. Successful fitting result was proved with predictive modeling analysis. CONCLUSION: Individual intrinsic factors should affect Cmax of olanzapine,which provided a useful tool for individualized drug therapy.
