Review of the potential pleiotropic effects of metformin in treating COVID-19. Authors explore the potential of metformin, a medication commonly used for type 2 diabetes, as an antiviral and anti-inflammatory agent in COVID-19. Metformin has demonstrated inhibitory effects on SARS-CoV-2 growth in cell culture models and promising results in reducing viral load and achieving undetectable viral levels in clinical trials. Additionally, metformin exhibits anti-inflammatory properties by reducing pro-inflammatory cytokines and modulating immune cell function, which may help prevent cytokine storm. The drug's ability to regulate Th17/Treg balance suggests its potential in mitigating inflammation and restoring T cell functionality. Furthermore, metformin's modulation of the gut microbiota and production of short-chain fatty acids may contribute to its therapeutic effects.
Reviews covering metformin for COVID-19 include De Jesús-González, Halma, Petakh, Tseng, Zhang.

Unveiling the potential pleiotropic effects of metformin in treating COVID-19: a comprehensive review
Pavlo Petakh, Iryna Kamyshna, Aleksandr Kamyshnyi
Frontiers in Molecular Biosciences, doi:10.3389/fmolb.2023.1260633
This review article explores the potential of metformin, a medication commonly used for type 2 diabetes, as an antiviral and anti-inflammatory agent in the context of coronavirus disease 2019 . Metformin has demonstrated inhibitory effects on the growth of SARS-CoV-2 in cell culture models and has shown promising results in reducing viral load and achieving undetectable viral levels in clinical trials. Additionally, metformin exhibits anti-inflammatory properties by reducing the production of pro-inflammatory cytokines and modulating immune cell function, which may help prevent cytokine storms associated with severe COVID-19. The drug's ability to regulate the balance between pro-inflammatory Th17 cells and anti-inflammatory Treg cells suggests its potential in mitigating inflammation and restoring T cell functionality. Furthermore, metformin's modulation of the gut microbiota, particularly changes in bacterial taxa and the production of short-chain fatty acids, may contribute to its therapeutic effects. The interplay between metformin, bile acids, the gut microbiome, glucagon-like peptide-1 secretion, and glycemic control has implications for the management of diabetes and potential interventions in COVID-19. By refreshing the current evidence, this review highlights the potential of metformin as a therapeutic option in the management of COVID-19, while also exploring its effects on the gut microbiome and immunometabolism.
