Exploring the knowledge and perception towards generic medicines among undergraduate medical and nursing students – A questionnaire-based comparative study

Background: Healthcare providers are still hesitant in prescribing generic medicines due to several misconceptions about bioequivalence, efficacy, quality, and safety of generic medicines as compared to their branded counterparts. Proper teaching and training help in positive changes in perception as well as the prescribing and dispensing practices of healthcare providers. Aim and Objectives: The aims of this study were to study the knowledge and perception about the generic medicine among 2nd year MBBS and nursing students and to find out the differences between the student’s responses. Materials and Methods: An observational cross-sectional study was conducted involving 83 2nd year MBBS students and 60 2nd year nursing students in Bundelkhand Medical College, Sagar (M.P.), India. Assessment of knowledge and perception about generic medicines using the normal 5-point Likert scale and calculation using the independent-samples Mann–Whitney U-Test and P < 0.05 was considered statistically significant for differences observed among the two groups. Results: Only 33% of MBBS students and 17% of nursing students were select correct answer for bioequivalence limits. Almost 82% of MBBS and 53% of nursing students were agreed toward generic medicines are less expensive than brand name medicines (P = 0.00). Only 45% of MBBS students and 15% of nursing students were disagreed toward generic medicines are of inferior quality to branded drugs (P = 0.001). About 37% of MBBS students and 20% of nursing students were disagreed toward generic medicines are less effective and less safe than brand name medicines (P = 0.01) and only 12% of MBBS students and 7% of nursing students were disagreed toward brand name medicine which are required to meet higher safety standards than generic medicines (P = 0.09). Conclusion: In our study, we found that significant knowledge gap with regard to the regulatory bioequivalence limits for generic medicines and misconceptions about generic drugs is also quite prevalent. Educational interventions are most important tool to improve knowledge and change in perceptions among healthcare students about generic medicines and eventually promote practice of prescribing cost-effective generic drugs.

Poor-quality medicines: a global threat to health / Lao Medical Journal

@#Poor quality medicines have been described as a global pandemic that threatens the lives of millions of people. The problem is much more severe in poor-resource countries where pharmaceutical legislation and regulation are limited. Poor quality medicines are divided into three categories: substandard, degraded and falsified and the countermeasures vary according to each category. The use of poor quality medicine leads from minimal to severe complications (including death) for the individuals but also harms the community. Furthermore, they lead to a loss of confidence of the patients in essential medicines, in manufacturers and in health system and they increase the work burden for health workers, customs and police. To detect them, different techniques have been developed, each with advantages and limits. This article describes these aspects of poor quality medicines and also presents the factors that contribute to the existence and spread of poor quality medicines. A section of the article is devoted to the issue of poor quality medicine in Laos.

An observational comparative study of cost between branded medicines and generic medicines.

Background: Same drug can be sold for different prices under different brand names due to various reasons. Branded medicine is the original product that has been developed by a pharmaceutical company and generic medicine is a copy of the original branded product, marketed after the expiry date of the patent and hence supposed to be of low cost as compared to their branded versions. The objective was to compare the costs of various branded and generic medicine and to ascertain the rationality of emphasizing generic versus branded prescription. Methods: Prices of 50 commonly used branded and generic medicines available as both branded and generic forms and in same concentration, dosage form and combination were selected and the percentage difference in the mean cost of generic and branded medicines was calculated. Results: The mean cost of 26 generic medicines out of the selected 50 medicines was higher than their branded versions. Mean cost of 20 branded medicines was higher than generic ones, and cost of 4 medicines was approximately same. Percentage difference in the mean costs of branded and generic medicines varied from <10% to >70%. Conclusions: Most of the drugs available in the market have brand names whether they are branded or generic medicines. Hence, doctor should write a cheapest known brand with the name of the generic salt in bracket so that the patient can buy another if that brand is not available. Furthermore, the Drug Controller of India should release a website where every doctor should be able to fi nd the cheapest and approved drugs in the market.

Estudo de perfil de dissolução dos medicamentos de referência, genérico e similar contendo cefalexina na forma farmacêutica cápsula / Study of dissolution profile of the pioneer brand name, generic and similar brand name pharmaceutical products containing cephalexin in the form of capsules

Com o avanço da tecnologia e das pesquisas envolvendo liberação de fármacos, modernização de testes e maior ênfase da previsibilidade de efeitos terapêuticos por meio dos testes in vitro, os testes de dissolução e os estudos de perfis de dissolução têm ganhado cada vez mais importância. Apesar de terem sido introduzidos inicialmente como uma forma de caracterizar o perfil de liberação de fármacos pouco solúveis, atualmente os testes de dissolução fazem parte das monografias de quase todas as formas farmacêuticas sólidas orais. Este trabalho teve como objetivo estudar o perfil de dissolução (porcentagem de fármaco dissolvido versus tempo) dos medicamentos de referência, genérico e similar contendo cefalexina 500 mg na forma farmacêutica de cápsulas. Foram analisadas três especialidades farmacêuticas (referência, genérico e similar), os quais foram submetidos ao teste de dissolução e perfil de dissolução in vitro. Os resultados obtidos no teste de dissolução permitem concluir que as amostras encontraram-se de acordo com as especificações e o perfil de dissolução deste medicamento, nesta forma farmacêutica, é considerado de dissolução rápida (85% de fármaco dissolvido em 15 minutos). Portanto, existe uma grande semelhança entre as curvas obtidas, o que sugere que se trata de equivalentes farmacêuticos.

With recent advances in technology and research into drug delivery, the modernization of tests and greater emphasis on the predictability of therapeutic effect by means of in vitro tests, the dissolution test and the study of dissolution profiles are gaining more and more importance. Though introduced initially as a way of characterizing the release profile of poorly soluble drugs, dissolution tests are currently part of pharmacopoeial monographs on almost all the oral solid pharmaceutical forms. The objective of this study was to determine the dissolution profile (percent drug dissolved versus time) of the pioneer brand, generic and similar pharmaceutical capsules containing 500mg cephalexin. Three pharmaceutical brands (reference, generic and similar) were subjected to the dissolution test and in vitro dissolution profiles were recorded. From the results of the dissolution test, it was concluded that the samples met the acceptance criterion, as no difference was observed in the percentage of the drug dissolved in a standard time. The dissolution profile indicated that this medicine, in this pharmaceutical form, dissolves readily (85% of the drug dissolved in 15 minutes) and the curves showed great similarity, suggesting that the 3 brands are pharmaceutically equivalent.
