A comparative study on perception and use of generic drugs between public and private health practitioners

Abstract

Context: The perception of generic drugs may vary significantly between government and private doctors because physicians in the private sector have more prescribing choices and flexibility. Hence, this study was undertaken to analyse the knowledge, attitude and perception (KAP) of government and private physicians on generic drugs. Materials and Methods: This was a questionnaire-based cross-sectional study conducted among physicians working in public and private health sectors. The questionnaire had 25 closed-ended questions related to the KAP of generic medicine. The overall scores were categorised using Bloom's cut-off point. The Chi-square or Mann–Whitney U-test was used to compare the differences between the two groups. Results: About 80% of the participants in both groups agreed that generic medicines contain the same active ingredients as brand-name drugs, are less expensive and are available in the Indian market. Nearly 84% of government physicians and only 64% of private physicians believed that generic medicines are just as effective and secure as branded medicines (P - 0.003). The majority of physicians from both groups concurred that there is a lack of quality check in generic drug manufacturing, and they require more information about bioequivalence studies. In both categories, about 75% of participants preferred generic medications for their patients. However, in both groups, more than 50% of physicians were concerned about therapeutic failure and expressed reluctance to prescribe generic medications in life-threatening situations. Conclusions: Knowledge and acceptance of generic drugs regarding efficacy, safety, bioequivalence and therapeutic failure are low among both government and private physicians.
