Nitazoxanide (Alinia®, Romark Laboratories) was synthesized based on the structure of niclosamide. In vitro studies have demonstrated activity against a broad range of parasites as well as some bacteria. Three controlled trials demonstrated efficacy in cryptosporidiosis, however, the efficacy in advanced AIDS patients (CD4 cell counts = 50) at approved doses was limited. Trials have also demonstrated efficacy comparable to metronidazole (Flagyl®, GD Searle and Co.) in giardiasis with fewer side… 

Drug Repurposing: The Anthelmintics Niclosamide and Nitazoxanide Are Potent TMEM16A Antagonists That Fully Bronchodilate Airways

For the first time, antagonists of TMEM16A and repositioning of niclosamide and nitazoxanide represent an important additional treatment for patients with severe asthma and COPD that is poorly controlled with existing therapies.

Nitazoxanide, an Antiprotozoal Drug, Reduces Bone Loss in Ovariectomized Mice by Inhibition of RANKL-Induced Osteoclastogenesis

NTZ could inhibit osteoclastogenesis and bone loss through modulation of the receptor activator of NF-κB ligand-induced STAT3-NFATc1 signaling pathway, which might be a potential alternative treatment regimen against bone destruction-related diseases including osteoporosis.
