Abstract: Antiepileptic drugs ( AEDs) should be used with individualized dsage regimens since they are metabolized by marked variability.It is an effective way to design individualized dosage regimens with population pharmacokinetic ( PPK) researching.There are lots of researches on PPK for antiepileptic drugs in the world, and many demographic features but genetic factors are analyzed in PPK models.CYP450 gene polymorphisms are important factors for interindividual variability.The latest advance of study for PPK is to analyze the effect on AEDs due to CYP450 gene polymorphisms, and to choose different initial doses according to gene polymorphisms.It will be valuable to facilitate individualized dosage regimen.However, one study indicates that the presently evaluated variant alleles in the CYP2C8, CYP3A4, CYP3A5 and ABCB1 genes did not explain the substantial interindividual variability in paclitaxel pharmacokinetics.Therefore,more deeply research should be done.

Key words: population pharmacokinetics, antiepileptic drugs, CYP450, gene polymorphisms
