Abstract

Objective : Bio-equivalence(BE) test is important mot only to ensure the quality of generic drugs, but also to promote drug substitution under the separation of prescribing and dispensing practice(SPD). This study was intended to investigate the perception of consumers, doctors, and pharmacists on the confidence of bio-equivalence(BE) assured drugs.
Method : Nation-wide telephone interview survey was conducted for 1,018 consumers, 800 doctors, and 806 pharmacists from September to October in 2003. Descriptive analysis and χ2 analysis were conducted.
Results : Even though people showed higher confidence level for the Bioequivalent drugs compared with Bio-inequivalent drugs, the confidence was generally low. Among those asked about the therapeutic substitutability of original drugs by BE versions, 95.78% of pharmacists responded "positive", while only 39.33% of consumers and 31.13% of doctors said so. The elderly, the less educated, who takes chronic disease medicine, pays high cost of prescription drugs, and are in the low income responded less aware of that. Also most consumers got information such as effect of drugs from either media or doctors.
Conclusions : In order for people to believe that BE drugs and original drugs are equivalent, we need to strengthen health education, and to clarify any misunderstanding. It is also necessary for the national policy to provide accurate information about drugs to the public.
