Niz Oral Suspension contains the active ingredient Nitazoxanide, a synthetic antiprotozoal agent. Nitazoxanide is well absorbed from GIT. It interferes with Pyruvate Ferredoxin Oxidoreductase (PFOR) enzyme dependent electron transfer reaction which is important for anaerobic glucose energy metabolism. This results in cell swelling, membrane damage resulting in dysfunction of the parasite. When Nitazoxanide is administered with food, the AUC in plasma is increased almost two-fold and the Cmax is increased by almost 50%.

Warning & Precaution:

Nitazoxanide is generally well tolerated. In placebo-controlled clinical trials, the incidence of side-effects did not differ significantly from those of the placebo. None of the 613 pediatric patients discontinued therapy because of side-effects. In controlled and uncontrolled clinical studies pediatric patients who received Nitazoxanide the side-effects were abdominal pain, vomiting and headache. These were typically mild and transient in nature. Side-effects occurring in less than 1% of patients are anorexia, flatulence, appetite increase, malaise, sweating and dizziness.
Pregnancy and Lactation:
Pregnancy Category B: This drug should be used during pregnancy only if clearly needed.
Nursing Mothers: It is not known whether Nitazoxanide is excreted in human milk. As many drugs are excreted in human milk, caution should be exercised when Nitazoxanide is administered to a nursing woman.
Nitazoxanide is highly bound to plasma protein (>99.9%). Therefore, caution should be used when administering Nitazoxanide concurrently with other highly plasma protein-bound drugs with narrow therapeutic window.
