In vitro anti-SARS-CoV-2 activity

Nitazoxanide shows anti-SARS-CoV-2 activity in Vero E6 cells and has broad activity against a range of viruses.  However, activity in Vero cells does not appear sufficient to establish effiacy in vivo, as hydroxychloroquine/chloroquine have strong anti-SARS-CoV-2 activity in Vero cells but fail in vivo, perhaps due to differences in TMPRSS2 expression.

Nitazoxnide may also "[potentiate] the production of type 1 interferons (alpha and beta) produced by the host’s fibroblasts," a possible mechanism of benefit in COVID-19.
