Efficacy and safety of Reyanning mixture combined with conventional Western medicine for treating COVID-19

Abstract

Abstract Background: Since its first report in December 2019, coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly emerged as a pandemic affecting nearly all countries worldwide. So far, there is no specific anti-coronavirus therapy approved for the treatment of COVID-19. In China, some traditional Chinese medicines (TCM) have been successfully applied to the treatment of SARS-CoV-2 and have achieved good clinical results, including the Reyanning mixture, but there is no systematic review about it. This study will systematically evaluate its efficacy and safety in the treatment of COVID-19. Methods: The following electronic bibliographic databases will be searched to identify relevant studies: PubMed, MEDLINE, EMBASE, CNKI, CBM, and Wanfang databases. We will use the Cochrane Handbook for Systematic Reviews of Interventions to assess the risk of bias. The protocol will be conducted according to the approach and Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). Manager 5.3 software and STATA 16.0 software were used to perform the meta-analysis. Results: The systematic review and meta-analysis aims to review and pool current clinical outcomes of Reyanning mixture for the treatment of COVID-19. Conclusion: The conclusion of this review will provide evidence to judge whether Reyanning mixture combined with Conventional Western Medicine is an effective and safe intervention for COVID-19.
