respectively. CONCLUSIONS A GC/MS method for the rapid and simultaneous determination of meperidine, normeperidine, tramadol, propoxyphene and norpropoxyphene in human plasma was developed, optimized and validated. This procedure was shown to be sensitive and specific using small specimen amounts, suitable for application in routine analysis for forensic purposes and therapeutic monitoring. To our knowledge
理由阿片类镇痛药与心脏复极的延长有关,这种情况可能是致命的。为了正确估计治疗剂量的哌替啶,去甲美定,曲马多,丙氧芬和正丙氧芬的风险/获益之间的平衡,有必要开发一种测定这些阿片类药物血浆浓度的分析方法。方法在这里,我们描述了一种方法,该方法结合了强碱处理以获得正丙氧基苯酰胺,然后进行一步洗脱固相萃取,无需进一步衍生。通过气相色谱/电子电离质谱(GC / EI-MS)在选定离子监测模式下进行分离和定量。通过添加氘代类似物作为内标物,用500μL血浆进行定量。结果该方法在所有分析物的线性范围为25-1000 ng / mL范围内均得到验证,相关系数高于0.990。定量下限为25 ng / mL。根据相对标准偏差计算的日内和日间精度分别为2.0-12.0%和6.0-15.0%。就相对误差而言,精度在±10%的区间内。绝对回收率和提取效率分别为81.0至111.0%和81.0至105.0%。结论建立
