In addition, the sources of the raw materials are rich, the preparation process is simple, the feasibility is strong, so the present invention is applicable to large-scale production and easy to popularize. The demand of the blood dialysis is increasing along with the increasing number of the patients with the medium and end-stage renal failure year by year; therefore the present invention can generate tremendous social and economic benefits in a short period.

The invention provides a flupirtine maleate capsule composition. The flupirtine maleate capsule composition contains flupirtine maleate and a solubilizer. The solubilizer is copovidone S630. The invention also provides a flupirtine maleate capsule preparation method having simple processes and quality controllability. a flupirtine maleate raw material and calcium hydrophosphate are mixed and sieved by a sieve of 60 meshes so that raw material and auxiliary material uniform mixing is guaranteed, a yield is improved and a production cost is reduced. The preparation method utilizes a dry granulation technology so that granule bulk density is large, and compared with the existing granules having small bulk density, the same weight of the granules obtained by the preparation method can be put into a small-volume capsule. The products obtained by the preparation method and the formula have qualified quality and stable drug effects and are conducive to large-scale production realization.
