The objective of this study was to assess the perceptions of opinion-leaders, patients and their accompanying family members or carers about generic drugs. Three groups of participants were surveyed: (i) 50 customers while they were visiting commercial pharmacies located in São Paulo city, Brazil, (ii) 25 patients and 25 companions while they were waiting at the university outpatient clinic, and (iii) 50 healthcare opinion-leaders from government, hospitals, health plans, academia, and pharmaceutical companies. The questions explored socio-demographic characteristics and perceptions regarding value attributes of generic drugs compared to brand name drugs. Respondents had an average age of 52 years and 53% were women. Respondents believed generic drugs to be cheaper than brand name drugs (97%), and 31% thought generic drugs to be less effective than brand name drugs. Also, generic drugs were perceived by 54% of respondents to be as safe as brand name drugs and 74% would prefer brand name drugs if there was no price difference. In conclusion, multiple factors may contribute to the decision to buy generic drugs; among these, perceived effectiveness, safety and price appear to be the most important factors.
本研究的目的是评估意见领袖、患者及其陪同的家庭成员或护理人员对仿制药的看法。对三组参与者进行了调查：（i）50名顾客在访问巴西圣保罗市的商业药店时，（ii）25名患者和25名陪同人员在大学门诊候诊时，以及（iii）50名来自政府、医院、健康计划、学术界和制药公司的医疗意见领袖。这些问题探讨了社会人口特征以及与品牌药相比仿制药的价值属性认知。受访者的平均年龄为52岁，53%为女性。受访者认为仿制药比品牌药便宜（97%），31%的人认为仿制药比品牌药效果差。此外，54%的受访者认为仿制药与品牌药一样安全，74%的人表示如果没有价格差异会更喜欢品牌药。总之，购买仿制药的决定可能受多种因素影响；其中，感知到的有效性、安全性和价格似乎是最重要的因素。
