    • The present invention provides a process for preparing the amorphous rabeprazole sodium. The process comprises the following steps: (a) Contacting rabeprazole sodium compound with a solvent system to thereby obtain a clear solution under a first temperature, wherein said solvent system is a mixture of at least two categories of organic solvents; (b) Stirring said clear solution of step (a) under a second temperature for a certain time period to obtain a solution containing resultant separated solid, wherein said second temperature is equal to or lower than said first temperature; (c) Filtering said solution containing resultant separated solid obtained from step (b) to obtain a wet solid; and (d) Drying said wet solid to obtain an amorphous rabeprazole sodium compound.
    • 本发明提供了制备无定形雷贝拉唑钠的方法。 该方法包括以下步骤:(a)用溶剂体系接触雷贝拉唑钠化合物,从而在第一温度下获得澄清溶液,其中所述溶剂体系是至少两类有机溶剂的混合物; (b)在第二温度下将所述步骤(a)的澄清溶液搅拌一定时间以获得含有所得分离固体的溶液,其中所述第二温度等于或低于所述第一温度; (c)将从步骤(b)获得的含有所得分离固体的所述溶液过滤,得到湿固体; 和(d)干燥所述湿固体以获得无定形雷贝拉唑钠化合物。
