Application
4-羟基苯乙妥英已被用于开发超高效液相色谱（UPLC）-串联质谱分析（MS/MS），以评估人尿或血浆样品中的细胞色素P450（CYP）探针药物及其相关代谢产物。4-羟基苯乙妥英还被用于开发一类基于亚2微米颗粒LC/MS/MS的方法来分析CYP450探针底物代谢产物。
Biochem/physiol Actions
4-羟基苯乙妥英分解代谢显示出了遗传多态性，并是细胞色素P450 2C19（CYP2C19）活性的一种直接指示剂。通过高效液相色谱对生物样品中4-羟基苯乙妥英的检测和定量已被充分的优化。

Using cyclodextrin micellar electrokinetic capillary chromatography (CD-MECC), baseline separation of mephenytoin, 4-hydroxymephenytoin and 4-hydroxyphenytoin enantiomers in urine was effected with beta-cyclodextrin. After single-dose administration of 100 mg of racemic mephenytoin, the 0-8 h urine was collected, and enzymatically hydrolyzed urine
