ABSTRACT
INTRODUCTION: Different therapies are currently used, considered, or proposed for the treatment of COVID-19;for many of those therapies, no appropriate assessment of effectiveness and safety was performed. This document aims to provide scientifically available evidence-based information in a transparent interpretation, to subsidize decisions related to the pharmacological therapy of COVID-19 in Brazil. METHODS: A group of 27 experts and methodologists integrated a task-force formed by professionals from the Brazilian Association of Intensive Care Medicine (Associação de Medicina Intensiva Brasileira - AMIB), the Brazilian Society of Infectious Diseases (Sociedad Brasileira de Infectologia - SBI) and the Brazilian Society of Pulmonology and Tisiology (Sociedade Brasileira de Pneumologia e Tisiologia - SBPT). Rapid systematic reviews, updated on April 28, 2020, were conducted. The assessment of the quality of evidence and the development of recommendations followed the GRADE system. The recommendations were written on May 5, 8, and 13, 2020. RESULTS: Eleven recommendations were issued based on low or very-low level evidence. We do not recommend the routine use of hydroxychloroquine, chloroquine, azithromycin, lopinavir/ritonavir, corticosteroids, or tocilizumab for the treatment of COVID-19. Prophylactic heparin should be used in hospitalized patients, however, no anticoagulation should be provided for patients without a specific clinical indication. Antibiotics and oseltamivir should only be considered for patients with suspected bacterial or influenza coinfection, respectively. CONCLUSION: So far no pharmacological intervention was proven effective and safe to warrant its use in the routine treatment of COVID-19 patients;therefore such patients should ideally be treated in the context of clinical trials. The recommendations herein provided will be revised continuously aiming to capture newly generated evidence.

CONTEXTO: A COVID-19 é uma pandemia de risco muito alto a nível global pela OMS. Até o momento não existem terapias específicas, embora diferentes tratamentos estejam em investigação. Mais recentemente, tem havido crescente interesse no uso da nitazoxanida no tratamento de COVID-19, dada sua atividade antiviral de amplo espectro. OBJETIVOS: Identificar, avaliar sistematicamente e sumarizar as melhores evidências científicas disponíveis sobre a eficácia e a segurança da nitazoxanida para COVID-19. MÉTODOS: Revisão sistemática rápida (rapid review methodology). RESULTADOS: Após o processo de seleção, foram avaliados cinco estudos clínicos em andamento. CONCLUSÃO: Cinco estudos com o objetivo de avaliar a eficácia e segurança da nitazoxanida no tratamento de COVID-19 estão em andamento. Devido à ausência de evidência sobre o uso deste medicamento para o tratamento de infecções por coronavírus que causem infecções respiratórias, não é possível recomendar seu uso como terapia para COVID-19.(AU)
