Problems solved by technology

[0003] The Chinese patent application with the application number CN03118521.5 discloses a preparation method of Tianmatou Fengling Tablets. Although the cyclodextrin in it can promote the dissolution of the drug to a certain extent, it needs a variety of auxiliary materials, and in the production process A large number of auxiliary materials will also make the tablet structure too tight during the tablet compression process, thereby affecting the disintegration of the tablet. At the same time, the tablet described in this application is a film-coated tablet, and the disintegration efficiency of the tablet will also be affected by the According to the excipient ingredients described in the application, without coating, it is very easy to hydrolyze, thus affecting the stability of pharmaceutical tablets
