Abstract
目的:建立测定人血浆中帕利哌酮浓度的方法.方法:血样以乙醚处理后采用反相高效液相色谱法进样测定.色谱柱为Agilent Eclipse PlusC18,流动相为甲醇-乙腈-水(1∶5∶14,加入1.88%正丁胺以及1.80%冰醋酸),流速为1.0 ml/min,检测波长为280nm,温度为室温(18~28℃),内标为曲唑酮,湿度<85%.结果:帕利哌酮血药浓度在2.81~180 ng/ml范围内线性关系良好(r=0.999 0);平均方法回收率在99.01%~104.23%之间,日内、日间RSD均<11%.结论:该法操作简便、准确、重复性好,可用于临床监测帕利哌酮的血药浓度.
