We define the ADR and the ADRcompensation in the theory research. The paper goes into detail about the ADR theory basis andthe responsibility constitution of other countries and provides the theory basis in order to make itclear why the victims should get the compensation and who should undertake the responsibility.(3)According to the analysis of the data statistical and the investigation, most reports come from themedical institutions while the reports from the production and operation enterprises are extremelyfew, only making up 1%. The speakers are mostly doctors. The serious ADR is about 2% andoccur at different ages. 50 -year-old middle-aged persons and old persons suffer from the ADReasily. In those reports, the ADR caused by using the one drug is about 90%; the ADR caused bythe anti-infection medicine ranks first due to using it wide in clinical medicine and applyingunreasonably. The intravenous injection easily causes the ADR.

对各国药品不良反应损害补偿的理论基础和责任构成进行阐述，为解决为什么要对药品不良反应受害者进行补偿、由谁承担责任提供了理论依据。3、我国药品不良反应现状研究方面，药品不良反应数据统计分析调查，发现报告主要来源于医疗机构，生产和经营企业报告数量极少，企业的报告数只占总数的1％，报告人都是以医生为主，严重不良反应发生的比例占药品不良反应报告总数的2％左右，不同年龄段都有药品不良反应发生，其中年龄大于50岁的中老年人发生的几率最大，在药品不良反应报告总数中，主要是使用一种药品的情形，占90％左右，抗感染药物占各类药物的首位，这与抗感染药物在临床广泛及不合理应用有关，静脉给药一直高居引起药品不良反应给药途径之首。
