In Vitro analysis of indomethacin for multiple human coronaviruses including SARS-CoV-2. Indomethacin exhibited antiviral activity against SARS-CoV-2 infection in human cell lines and lung airway organoid models. Treatment with indomethacin reduced SARS-CoV-2 viral RNA levels and infectious virus production. The anti-SARS-CoV-2 effect occurred at the post-entry stage of the viral life cycle. The EC50 (half maximal effective concentration) of indomethacin against SARS-CoV-2 was 16.69 μM, with a selectivity index around 6, indicating a reasonable therapeutic window between antiviral activity and cytotoxicity. Combining indomethacin with other antivirals showed synergistic effects.
4 preclinical studies support the efficacy of indomethacin for COVID-19:

In Vitro studies are an important part of preclinical research, however results may be very different in vivo.
