Nitazoxanide

Nitazoxanide (NTZ) is licensed in the USA for treatment of diarrhoea caused by Cryptosporidium parvum and Giardia lamblia. NTZ is a pro-drug for tizoxanide, which also has broad spectrum antiviral properties, has many viral indications and shows promising pharmacodynamics against Coronaviridae. NTZ was identified as a first-in-class broad-spectrum antiviral drug and has been repurposed for the treatment of influenza. In vitro studies evaluating tizoxanide, the active circulating metabolite of NTZ, inhibits the replication of broad range of influenza A and B, HIN1, H3N2, H3N2V, H3N8, H5N9, H7N1 and oseltamivir resistant strain and coronaviruses . It has been shown to have anti-viral activity against several viruses including Ebola, hepatitis B and C, rotavirus and norovirus.
