NCIt definition : A synthetic benzamide with antiprotozoal activity. Nitazoxanide exerts its antiprotozoal
activity by interfering with the pyruvate ferredoxin/flavodoxin oxidoreductase dependent
electron transfer reaction, which is essential to anaerobic energy metabolism. PFOR
enzyme reduces nitazoxanide, thereby impairing the energy metabolism. However, interference
with the PFOR enzyme-dependent electron transfer reaction may not be the only pathway
by which nitazoxanide exhibits antiprotozoal activity. Nitazoxanide is active against
Giardia lamblia and Cryptosporidium parvum.;
