Abstract

The invention discloses a nateglinide tablet and a method for preparing the nateglinide tablet through a direct compression method, wherein each one thousand of nateglinide tablets are prepared from 30g of nateglinide, 45g of diluent, 35g of disintegrating agent, 1g of lubricating agent and 3g of flow aid, the preparation method for preparing the nateglinide tablet through direct compression by using a compressible auxiliary material comprises a process of weighing and matching, screening, mixing, tabletting, inner packing and packing under the D level condition, the nateglinide tablet and the method, provided by the invention solve the problems of cracking tablet, rough tablet, sticking and the like of a nateglinide tablet prepared through a traditional wet method.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a nateglinide tablet, and also relates to a method for preparing the nateglinide tablet by a direct tableting method. technical background [0002] Nateglinide is a derivative of D-phenylalanine. It mainly has two crystal forms, B-type and H-type. There are certain differences in the physical properties of the two crystal forms. The final product is H-type crystal. The drug causes Ca 2+ influx, intracellular Ca 2+ The concentration increases, thereby stimulating the secretion of insulin. The drug was first developed by the Swiss company Basel and put on the market in 1999. As a representative of a new generation of hypoglycemic drugs with an amino acid structure, it is not only the first insulin-secreting amino acid derivative for the treatment of type 2 diabetes, but also the only non-sulfonylurea insulin secretagogue with an amino acid structure. Compared with other oral...
