细胞色素P450酶基因多态性的研究进展及临床意义

细胞色素P450（cytochrome P450,CYP）是重要的药物代谢酶,参与催化多种内源和外源化合物,特别是多种临床药物的生物转化。CYP存在广泛的基因多态性和表型多态性,体现在个体对于各种化合物的代谢存在明显差异。本文综述了CYP的基因多态性、与药物代谢相关的CYP各亚型的特点和临床意义,主要目的是合理解释和预测临床上药物间相互作用和药物不良反应等,为实现临床个体化给药提供科学依据。

Research development and clinical significance of genetic polymorphism of CYP450

Cytochrome P450 is the very most important enzyme of dmg metabolism.It involves in biotransformation of various endogenous and exogenous compounds,especially for clinical drugs.There are many polymorphisms of gene and phenotype,resulting in significant individual variability of different kinds of compounds.This article reviews the genetic polymorphisms of CYP,the characters and clinical meanings of diverse subgroups that relevant to drug metabolism in recent years.The major object of this article is reasonably explaining and predicting the interaction of clinical drugs and the drug adverse reaction in order to providing scientific evidences for the individual administration in clinic.
