Where is Nitazoxanide used?

Nitazoxanide is a prescription medicine used for the treatment of Traveler’s diarrhea that is caused by Cryptosporidium or Giardia. 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.

Nitazoxanide is an artificial antiprotozoal agent for oral administration. It is a light yellow crystalline powder. This is considered the first drug to treat cryptosporidium and effective for the treatment of diarrhea. The Food and Drug Administration (FDA) has approved this medication.

How does Nitazoxanide work?

Nitazoxanide works by preventing the development 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.
