What is Alinia used for?

This oral medicine Alinia (nitazoxanide) is used to treat diarrhea caused by Giardia lamblia or Cryptosporidium parvum. This could be prescribed for children and adults. However, this medication has not been effective in treating diarrhea caused by Cryptosporidium parvum among immunodeficient patients or patients with HIV.

This is available in Alinia 500 mg tablet forms.

How does Alinia work?

This antiprotozoal drug is believed to work by disrupting the energy metabolism in anaerobic microbes. This is done through the inhibition of the pyruvate: ferredoxin/flavodoxin oxidoreductase (PFOR) cycle. It also induces lesions in the cell membranes and depolarizes the mitochondrial membrane while inhibiting certain enzymes.
