Nitazoxanide and Alcohol/Food Interactions

ADJUST DOSING INTERVAL: Food enhances the bioavailability of the pharmacologically active metabolite tizoxanide (desacetyl-nitazoxamide) from nitazoxanide administration. According to the product labeling, administration of nitazoxanide tablets with food increases the area under the plasma concentration-time curve (AUC) of tizoxanide and tizoxanide glucuronide in plasma by almost 2-fold and the peak plasma concentration (Cmax) by almost 50%. Administration of nitazoxanide oral suspension with food increases the AUC of tizoxanide and tizoxandie glucuronide by about 45% to 50% and the Cmax by less than 10%.

MANAGEMENT: Nitazoxanide tablets and oral suspension were administered with food in clinical trials and are recommended to be administered with food to ensure maximal drug levels in plasma.
