Abstract:

The saturated and supersaturated characteristics of nitazoxanide in DMF, DMSO, methanol and acetone at different temperatures were investigated by using the laser detection technique. The crystallization metastable zone widths of nitazoxanide were obtained at different temperatures in the above four solvents. The results indicated that the solubility, supersolubility and the metastable zone width of nitazoxanide enhance with increasing temperature. At the same temperature, the metastable zone width of nitazoxanide relations as follows:acetone<DMSO<methanol<DMF.

Key words: nitazoxanide, solubility, supersolubility, metastable zone width
