Challenges to the drug quality control in Brazil

Abstract Introduction Scientific and technological development, as well as the adoption of public policies aiming drugs cost reduction, has broadened the population's access to therapeutic alternatives. These alternatives include generic drugs, biosimilars, nanomedicines and non-biological complexes. Already marketed categories require their own procedures to guarantee their quality, therapeutic efficacy and safety. This article assesses the current Brazilian scenario in this regard, pointing to situations that will surely have to be addressed in a near future. Methodology Data was obtained in the electronic databases MEDLINE, PubMed and SCIELO, searching for original articles, both Portuguese and English, retrospectively indexed back to 1999 using relevant search terms, both in English and in Portuguese. More than 50 scientific articles were found. Results and Discussion Most of the evaluated articles point to problems both in the manufacture and in the control of generic and biosimilar drugs. In fact, scientific publications have proven these problems in the most varied markets including Brazilian. On the other hand, new drug forms are being created and need the development of legislation and specific methodologies to guarantee the quality of these products. An evaluation of the current Brazilian system of registration and quality control points out some flaws and especially the lack of a better structured and active pharmacovigilance in the country. Conclusion The current scenario demonstrates the need of the responsible organs in the country to review the current system and improve it, as well as to prepare for the confrontation with other, even more complex, demands that are already under development.
