A method is described for the determination of meperidine and its pharmacologically active metabolite, normeperidine, in blood, plasma, and urine using gas chromatography with nitrogen-phosphorus detection. Structural analogs of both meperidine and normeperidine were used as internal standards. Unlike previously reported assays, this procedure was sensitive and convenient enough for use in pharmacokinetic
描述了一种使用氮磷检测的气相色谱法测定血液,血浆和尿液中甲哌丁啶及其药理活性代谢物诺美哌啶的方法。哌啶和去甲哌啶的结构类似物均用作内标。与以前报道的测定法不同,此程序灵敏且方便,足以用于单次注射哌替啶后的哌替啶和去甲哌啶的药代动力学研究。该测定对从1毫升生物样品中提取的5 ng甲哌啶/ ml和2.5 ng甲哌啶/ ml敏感。在这些浓度下,测定之间的变异系数分别为9.4%和10.4%。
