Abstract

The invention provides a method for preparing voglibose particles. The particles are prepared through a one-step prilling process,the friability is low,and the roundness is good. Voglibose can be dissolved out fast,the content uniformity is good,and the voglibose particles are suitable for being further prepared into capsules,tables (including dispersible tablets and orally disintegrating tablets)and granules. According to the preparation idea,the voglibose is added into a polar solvent containing a water-soluble adhesive,and the mixture is sprayed into a one-step pelletizer containing a diluent and a disintegrating agent in a top spraying prilling mode. The preparation method is easy to operate,the labor intensity is reduced,and the preparation method is suitable for large-scale production.

Description

technical field [0001] The invention relates to a preparation method of voglibose granules, belonging to the field of medicine and biology. Background technique [0002] Diabetes mellitus is an endocrine and metabolic disorder, a chronic disease characterized by hyperglycemia caused by insulin secretion and utilization disorders. According to the statistics of the International Diabetes Federation (IDF), as of 2015, there are 415 million diabetic patients (prevalence rate of 8.8%) and 318 million pre-diabetic patients (prevalence rate of 6.7%) worldwide. Without intervention, by 2040 there will be 642 million people with diabetes and 481 million people with prediabetes. Of these, 46.5% of the 415 million diabetics were undiagnosed. 5.1 million people die from diabetes-related diseases every year, accounting for 8.39% of the total deaths. According to the forecast of the World Health Organization (WHO), the global medical expenditure on diabetes will reach 53 billion US do...
