  • nitazoxanide
  • nitazode
  • nitazoxanida
  • nizonide
a 5-nitrothiazolyl derivative used for a broad range of intestinal parasitic infections including CRYPTOSPORIDIUM and GIARDIA; it is a redox-active nitrothiazolyl-salicylamide prodrug; structure given in first source. It was investigated as a potential treatment for COVID-19 based on its broad antiviral activity, including in vitro activity against SARS-CoV-2 and MERS-CoV; however, there are no data to support the use of nitazoxanide in the treatment of COVID-19.
