Our aim was to characterize Adverse Drug Reactions (ADRs) related to drug-drug interactions (DDIs) related to involvement of cytochrome P450 (CYP450) isoenzymes in a pharmacovigilance database.
ADRs recorded by Midi-Pyrénées PharmacoVigilance center (France) between 1 January and 31 August 2008 were extracted from the French PharmacoVigilance Database (FPVD).
Among the 1,205 reported ADRs, 16 (1.3 %), can be explained by involvement of CYP450 isoenzymes (including 4 "serious"). All interactions involved CYP inhibitors, mainly for CYP3A4/5.
The percentage of ADRs reported in the pharmacovigilance database and related to CYP450-induced DDIs appears to be relatively low (~ 1-2 %).
本研究旨在通过药物警戒数据库,对与细胞色素 P450(CYP450)同工酶相关的药物-药物相互作用(DDI)引起的不良反应(ADR)进行分析。
从法国药物警戒数据库(FPVD)中提取 2008 年 1 月 1 日至 8 月 31 日期间,在 MIDI-PYRENEES 药物警戒中心(法国)记录的 ADR。
在报告的 1205 例不良反应中,有 16 例(1.3%)可归因于 CYP450 同工酶的参与(包括 4 例“严重”)。所有的相互作用均涉及 CYP 抑制剂,主要是 CYP3A4/5。
药物警戒数据库中报告的与 CYP450 诱导的 DDI 相关的不良反应比例似乎相对较低(约 1-2%)。
