Nitazoxanide works by disrupting the electron transfer reaction of the pyruvate; oxidoreductase (PFOR) enzyme, which is crucial for anaerobic energy metabolism. Essentially this disrupts how the offending parasites produce energy.

Nitazoxanide is processed by the body and transformed into nitazoxanide, which is its active form. Tizoxanide then spreads throughout the body, specifically targeting organisms while leaving the body's natural microbiota relatively unaffected. Interestingly this selective mechanism ensures an impact on the host, thus highlighting its effectiveness in treating antiprotozoal infections.

Nitazoxanide is an antiviral drug with broad antiviral activity and may have the potential as an effective alternative or an addition to standard treatment for the treatment of the hepatitis C virus¹². It is also being researched as a potential treatment for rotavirus gastroenteritis³⁴, as its active metabolite nitazoxanide demonstrated efficacy against several RNA viruses in clinical trials⁴.
