按照WHO国际药物监测合作中心的规定,药物不良反应(adverse drug reactions,简称ADR)系指正常剂量的药物用于预防、诊断、治疗疾病或调节生理机能时出现的有害的和与用药目的无关的反应。该定义排除有意的或意外的过量用药及用药不当引起的反应。
我国是WHO国际药物监测合作计划的成员国,在ADR监测工作中应遵守WHO所规定的ADR定义进行ADR报告。为正确理解WHO的ADR定义,
现将原文摘录如下:
A reaction which is noxious and unintended ,and which occurs at doses normally used in man for the prophylaxis, diagnosis, or therapy of diseases ,or for the modification of physiological function.This definition excludes accidental or deliberate excessive dosage or maladministration.
