Nitazoxanide, a medication used to treat parasites, has been shown to be as effective as vancomycin in a clinical trial for the treatment of C difficile.

A review of 10 clinical trials evaluating the treatment of an initial episode of CDI showed that nitazoxanide and teicoplanin did not demonstrate inferiority relative to vancomycin and metronidazole. [75] However, other antimicrobials, including rifampin, and the toxin-binding polymer tolevamer, did show inferiority compared with vancomycin and metronidazole. [75]
