Knowledge and perception differences towards generic medicines consumption among consumers

Abstract

The objective of this study was to evaluate the population behavioural influence towards generic medicines use in a Klang Valley. A self-administered questionnaire in the Klang Valley, Malaysia, was distributed conveniently. A total of 222 respondents have participated in the study (response rate 57.8%). The majority of the respondents (87.7%) have reported considerable amount of knowledge on the generic medicine availability in the market. In comparison of sociodemographic influence, only household size was found to influence the respondent’s knowledge and curiosity. For the perception, there was a statistically significant difference in attitude scores for respondents who had good level of knowledge (M = 3.322, SD = 0.516) and poor level of knowledge (M = 3.011, SD = 0.591) towards generic medicines; t(220) = –4.180, p < 0.05. In terms of subjective norms, data findings indicate a statistically significant difference in scores for respondents who had good level of knowledge (M = 3.456, SD = 0.704) and poor level of knowledge (M = 3.057, SD = 0.616) towards generic medicines; t(220) = –4.393, p < 0.05. Similarly, this study found a statistically significant difference in perceived behavioural control scores for respondents who had good level of knowledge (M = 3.605, SD = 0.548) and poor level of knowledge (M = 3.121, SD = 0.577) towards generic medicines; t(220) = –6.350, p < 0.05. Therefore, these results reveal that good level of knowledge really influence the level of perceptions among consumers of generic medicines. It is imperative that more initiatives to be introduced by the government to promote the practice to prescribe generic drugs to the population. The need to educate both health professionals and patients on the availability of the cheaper and bioequivalence medicine should be put into formality, thus increasing the awareness of the patient of the generic medicine and next reduce the dependency of the costlier innovator brand medicine in the prescription at both public and private healthcare settings.
