Nitazoxanide is used to treat diarrhea caused by Giardia or Cryptosporidium. These conditions are sometimes called Traveler’s diarrhea. It is a kind of condition that may be also caused by a certain parasite infection of the intestines. This medication is used in adults and children who are at least 1 year old.
How does Nitazoxanide work?
Nitazoxanide works by stopping the growth of certain protozoa that cause diarrhea. The activity of this drug is believed to be due to interference with the pyruvate: ferredoxin oxidoreductase enzyme-dependent electron transfer reaction. It is vital to anaerobic energy breakdown. Experts have presented that the PFOR enzyme from Giardia lamblia directly lessens Nitazoxanide. It is by transferring electrons in the absence of ferredoxin. The DNA derived PFOR protein sequence of Cryptosporidium parvum appears to be similar to that of Giardia lamblia.
