摘要 为了探讨高效液相色谱法同时测定苯巴比妥PB、苯妥英PHT、卡马西平CBZ血药浓度的最佳实验条件,将标本在pH76条件下用二氯甲烷提取后经高纯度氮气在50℃水浴中吹干,再用甲醇重溶后进行色谱分析。色谱条件:YWGC18柱250mm×46mm,10μm,流动相甲醇:水为60∶40,流速1mlmi
,柱温40℃,波长254
m。结果PB、PHT、CBZ的最低检出浓度各为067μgml、094μgml和031μgml。在三个不同水平下,PB、PHT、CBZ的平均回收率各为9814、9672和9936,日内和日间变异均低于625,内源性物质及10种常用药物未见干扰,在分析范围内具有良好的线性关系。该方法操作简便、快捷、准确,可满足临床和科研的需要。r

  癫痫是神经系统一种常见病,绝大多数病人需长期规范地服药治疗。为了提高临床用药的有效性和安全性,减少或避免毒副反应,并为用药过量的中毒诊断和处理提供可靠的客观依据,很有必要进行此类药物在血液中浓度的监测。用高效液相色谱法HPLC同时测定数种抗癫痫药已有不少报道,但流动相r
