摘要
目的探讨细胞色素P450(CYP)2A6及CYP2B6等位基因多态性与丙戊酸钠血药浓度的关系。方法选择165例服用丙戊酸钠单药治疗且无肝肾功能异常的癫疒间患者,应用多聚酶链反应(PCR)方法分别进行CYP2A6(95例)和CYP2B6(70例)等位基因多态性频率分析;应用荧光偏振免疫法(FPIA)测定含不同等位基因患者丙戊酸钠的血药浓度。结果95例患者中,CYP 2A6*4等位基因频率为13.2%,CYP2A6*4等位基因携带者丙戊酸钠的血药浓度[(4.23±0.27)mg/ml]明显高于非CYP2A6*4等位基因携带者[(3.35±0.38)mg/ml](P<0.05);70例患者中,CYP2B6*6等位基因频率为24.3%,CYP2B6*6等位基因携带者丙戊酸钠的血药浓度[(4.12±0.34)mg/ml]明显高于非CYP2B6*6等位基因携带者[(3.07±0.28)mg/ml](P<0.05)。结论CYP2A6或(和)CYP2B6等位基因多态性均影响丙戊酸钠的血药浓度,CYP2A6*4或(和)CYP2B6*6等位基因携带者丙戊酸钠用量应低于常规剂量,以减少不良反应的发生和避免药物资源的浪费。
