RESUMEN
Resumo Os estudos em vigilancia farmacológica e ecofarmacológicas possibilitam o monitoramento, identificagao e minimi-zagao de efeitos nocivos advindos do uso de medicamentos. Diante disso, o presente estudo teve como objetivo descrever o cenário atual da farmacoepidemiologia e ecofarmacovigilancia no Brasil, no que se refere a produgao, registro, comerciali-zagao e uso de medicamentos. Foi realizado um levantamento sistemático, através dos bancos de dados PubMed/Medline, Lilacs e SciELO, cuja temática envolveu pesquisas em farmacoeconomia, farmacovigilancia, ecofarmacovigilancia e estudo da utilizagao de medicamentos no Brasil de 2001 a 2019. As publicagóes distribuíram-se de forma desigual entre as regióes brasileiras. Pacientes hipertensos, oncológicos e as gestantes foram os grupos de risco mais citados e os antimicrobianos, psicotrópicos e antineoplásicos os grupos farmacológicos mais discutidos. Custo de cuidados em saúde foi a temática mais abordada no contexto da farmacoeconomia e grande parte dos trabalhos destinou-se a análise e obtengao de dados referentes ao uso de medicamentos e suas reagóes adversas. Em relagao a ecofarmacovigilancia nao foram encontradas publicagóes no Brasil que contemplem essa área. Apesar dos avangos da legislagao farmacoepidemiológica e melhorias nos processos de fiscalizagao, no que tange a vigilancia da produgao, registro, comercializagao e uso de medicamentos, ainda permanecem carencias, quanto ao aporte de uma visao científica direcionada, sobretudo ao gerenciamento e diferentes usos dos recursos terapéuticos, e económicos do sistema de saúde brasileiro, bem como uma visao ambiental referente ao uso de medicamentos.
Abstract Studies in pharmacological and ecopharmacological surveillance make it possible to monitor, identify and minimize harmful effects arising from the use of drugs. Therefore, the present study aimed to describe the current scenario of pharmacoepidemiology and ecopharmacovigilance in Brazil, about the production, registration, marketing, and use of medicines. A systematic survey was carried out through the PubMed/Medline, Lilacs, and SciELO databases, whose theme involved research in pharmacoeconomics, pharmacovigilance, ecopharmacovigilance, and the study of drug use in Brazil from 2001 to 2019. Publications were unevenly distributed between Brazilian regions. Hypertensive patients, cancer patients, and pregnant women were the most cited risk groups, and antimicrobials, psychotropics, and antineoplastics were the most discussed pharmacological groups. Cost of health care was the most discussed topic in the context of pharmacoeconomics and most of the work was aimed at analyzing and obtaining data regarding the use of drugs and their adverse reactions. Regarding ecopharmacovigilance, no publications were found in Brazil covering this area. Despite advances in pharmacoepidemiological legislation and improvements in inspection processes, regarding the surveillance of the production, registration, commercialization, and use of medicines, there are still gaps regarding the contribution of a directed scientific vision, especially to the management and different uses of resources. therapeutic and economic aspects of the Brazilian health system, as well as an environmental vision regarding the use of medicines.
Resumen Los estudios de vigilancia farmacológica y ecofarmacológica permiten controlar, identificar y minimizar los efectos nocivos derivados del uso de los medicamentos. Ante esto, el presente estudio tuvo como objetivo describir el escenario actual de la farmacoepidemiología y la ecofarmacovigilancia en Brasil, en relación con la producción, el registro, la comercialización y el uso de los medicamentos. Se realizó una encuesta sistemática, a través de las bases de datos PubMed/Medline, Lilacs y SciELO, cuya temática involucró investigaciones sobre farmacoepidemiología, farmacovigilancia, ecofarmacovigilancia y estudio del uso de medicamentos en Brasil desde 2001 hasta 2019. Las publicaciones se distribuyeron de forma desigual entre las regiones brasileñas. Los pacientes hipertensos, los pacientes oncológicos y las mujeres embarazadas fueron los grupos de riesgo más citados y los antimicrobianos, los psicotrópicos y los antineoplásicos fueron los grupos farmacológicos más discutidos. El coste de la asistencia sanitaria fue el tema más abordado en el contexto de la farmacoeconomía y la mayoría de los trabajos estaban dirigidos a analizar y obtener datos sobre el uso de los medicamentos y sus reacciones adversas. En cuanto a la ecofarmacovigilancia, no se encontraron publicaciones en Brasil que aborden esta área. A pesar de los avances en la legislación farmacoepidemiológica y de las mejoras en los procesos de inspección, en lo que respecta a la vigilancia de la producción, registro, comercialización y uso de los medicamentos, todavía falta una visión científica dirigida, sobre todo, a la gestión y a los diferentes usos de los recursos terapéuticos y económicos del sistema de salud brasileño, así como una visión ambiental en cuanto al uso de los medicamentos.
RESUMEN
Pharmaceutical residues are not completely removed in wastewater treatment plants (WWTPs) becoming contaminants in aquatic ecosystems. Thereby, it is important to investigate their concentrations in the environment and the possible consequences of their occurrence, including for human health. Here, we briefly reviewed the paths of pharmaceuticals to reach the environment, their behavior and fate in the environment, and the possible consequences of their occurrence. Moreover, we synthetized all the studies about the detection of pharmaceuticals in Brazilian water bodies and the available ecotoxicological knowledge on their effects. In this study, when we compare the data found on these compounds worldwide, we observed that Brazilian surface waters present considerable concentrations of 17α-ethinylestradiol, 17ß-estradiol, and caffeine. In general, concentrations found in aquatic systems worldwide seems to be low; however, ecotoxicological tests showed that even these low concentrations can cause sublethal effects in biota. The knowledge about the effects of continuous exposure and mixtures is sparse. In summary, new research is urgently required about the effects of these compounds in biota-including long-term exposition and mixture tests-and on specific technologies to remove these compounds in water bodies and WWTPs, besides the introduction of new policies for pharmaceutical use.
