What do people really think about generic drugs? A systematic review and critical appraisal of literature on stakeholder perceptions of generic medicines.

Institution: BioMed Central
Region:
Description:

Background: Considerable emphasis is presently being placed on usage of generic medicines by governments
focussed on the potential economic benefits associated with their use. Concurrently, there is increasing discussion
in the lay media of perceived doubts regarding the quality and equivalence of generic medicines. The objective of
this paper is to report the outcomes of a systematic search for peer-reviewed, published studies that focus on
physician, pharmacist and patient/consumer perspectives of generic medicines.
Methods: Literature published between January 2003 and November 2014, which is indexed in PubMed and
Scopus, on the topic of opinions of physicians, pharmacists and patients with respect to generic medicines was
searched, and articles within the scope of this review were appraised. Search keywords used included perception,
opinion, attitude and view, along with keywords specific to each cohort.
Results: Following review of titles and abstracts to identify publications relevant to the scope, 16 papers on
physician opinions, 11 papers on pharmacist opinions and 31 papers on patient/consumer opinions were included
in this review. Quantitative studies (n = 37) were the most common approach adopted by researchers, generally in
the form of self-administered questionnaires/surveys. Qualitative methodologies (n = 15) were also reported, albeit
in fewer cases. In all three cohorts, opinions of generic medicines have improved but some mistrust remains, most
particularly in the patient group where there appears to be a strongly held belief that less expensive equals lower
quality. Acceptance of generics appears to be higher in consumers with higher levels of education while patients
from lower socioeconomic demographic groups, hence generally having lower levels of education, tend to have
greater mistrust of generics.
Conclusions: A key factor in improving confidence in generic products is the provision of information and
education, particularly in the areas of equivalency, regulation and dispelling myths about generic medicines
(such as the belief that they are counterfeits). Further, as patient trust in their physician often overrules their
personal mistrust of generic medicines, enhancing the opinions of physicians regarding generics may have
particular importance in strategies to promote usage and acceptance of generic medicines in the future.
