“…Factors related to the behavior of consumers, prices, or even the suggestions of clerks may be influencing this choice. A study conducted in Brazil has shown differences on the perceptions regarding generic drugs 28 . Nardi et al 28 have pointed out price, effectiveness, and safety as important factors that may contribute to the decision to purchase generic drugs.…”

OBJECTIVEThe objective of this study is to identify factors associated with the preference for purchasing generic drugs in a medium-sized municipality in Southern Brazil.METHODSWe have analyzed data from a population-based cross-sectional study conducted in 2012 with a sample of 2,856 adults (≥ 20 years old). The preference for purchasing generic drugs was the main outcome. The explanatory variables were the demographic and socioeconomic variables. Statistical analyses included Poisson regressions.RESULTSThe preference for purchasing generic drugs was 63.2% (95%CI 61.4–64.9). The variables correlated with this preference in the fully adjusted models were: male (prevalence ratio [PR] = 1.08; 95%CI 1.03–1.14), age of 20–39 years (PR = 1.10; 95%CI 1.02–1.20), low socioeconomic status (PR = 1.15; 95%CI 1.03–1.28), and good knowledge about generic drugs (PR= 4.66; 95%CI 2.89–7.52). Among those who preferred to purchase generic drugs, 55.1% have reported accepting to replace the prescribed drug (if not a generic) with the equivalent generic drug. Another correlate of the preference for purchasing generic drugs was because individuals consider their quality equivalent to reference medicines (PR = 2.15; 95%CI 1.93–2.41).CONCLUSIONSKnowledge about generic drugs was the main correlate of the preference for purchasing generic drugs. The greater the knowledge or positive perception about generic drugs, the greater is the preference to purchase them. Therefore, educational campaigns for healthcare professionals and consumers appear to be the best strategy for expanding the use of generic drugs in Brazil.

“…Besides the changes in the environment, the relevance of this study also finds support in the insufficiency of studies on the subject. Although this problem has been studied in IJPHM 11,4 several countries (Decollogny et al, 2011;Dunne et al, 2014;Frisk et al, 2011;Kjoenniksen et al, 2006;Kobayashi et al, 2011;Nardi and Ferraz, 2016;Rathe et al, 2013;Rozano Suplet et al, 2009), previous research is either too descriptive, lacking the explanatory power or do not take a consumer behaviour perspective. Moreover, regarding the Portuguese reality, there are few studies (Dylst, 2012;Quintal and Mendes, 2012;Simoens, 2009;Vogler, 2012) that look at the choice process of mandatory prescribed drugs, and all of them prior to the most recent legislation change, with the exception of Duque et al (2014).…”

Purpose This paper aims to contribute to the understanding of what influences consumers’ choice of mandatory prescribed drugs, by looking with more detail to the substitution of branded drugs by generics. Specifically, this research looks at three factors that can influence this decision, namely, participative decision-making, perceived risk and price consciousness, within the recent changes introduced in the Portuguese pharmaceutical market by new legislation. Design/methodology/approach A cross-sectional study was conducted, using a self-administered questionnaire, to survey a sample of consumers/patients that visited a doctor and were prescribed some kind of drug. Data were treated using factor analysis for dimensionality reduction purposes and regression analysis to test the main hypothesis. Findings The results show that participative decision-making has no impact on purchase decision of generics, while perceived risk and price consciousness show a predictive power regarding purchase intention of generic drugs. Research limitations/implications Although the results are only applicable to the Portuguese context, it draws important conclusions regarding consumers’ behaviour when choosing between branded and generic drugs. Practical implications Knowing what influences consumers’ choices of generic drugs contributes to tune marketing strategies and actions. For public institutions, this paper offers insights on how to adapt public policies. Originality/value This paper is valuable because it is the first to look at the Portuguese pharmaceutical market from a consumer behaviour perspective since new legislation was set up.

“…É importante ressaltar que estes são submetidos aos testes de avaliação que podem garantir a eficácia de ambos, o que favorece a satisfação e confiança na população. Nardi & Ferraz (2016) observaram que a maioria das pessoas entrevistadas acreditam que os medicamentos genéricos e o medicamento de marca foram igualmente eficazes (66%), e que os medicamentos genéricos causam o mesmo efeito que o de marca (90%) (28) , o que corrobora para um melhor aceitação dos medicamentos genéricos por parte da população usuária de medicamentos, em comparação aos de referência, confiança esta que tem crescido a cada dia.…”
