Problems solved by technology

For example, in the Chinese invention patent application document with the publication number CN103845332A, a dasatinib pharmaceutical composition and its preparation method are disclosed. The blocker in the invention can improve the microenvironment of the solid preparation, and can improve the Stability and dissolution rate; its defect is: the particle size of dasatinib used in this invention is micron order, only optimizing the formula can not solve the problem of insoluble drug itself
In the Chinese invention patent application document with the publication number CN105560247A, a dasatinib composition tablet and its preparation method are disclosed. The dasatinib composition tablet in this invention has high dissolution rate and good stability. Low moisture and impurity content; the disadvantage is that the preparation process is time-consuming and difficult to produce in large quantities
In the Chinese invention patent application document with the publication number CN105106159A, a drug dasatinib composition tablet for the treatment of blood cancer is disclosed. The invention uses a new crystal form of dasatinib to prepare the tablet. The dissolution rate of the existing technology has been improved; the disadvantage is that the improvement effect of the dissolution rate and bioavailability of the drug is limited by adjusting the formulation of the preparation and changing the crystal form of the active ingredient of the drug.
[0008] In summary, the above-mentioned existing methods have the disadvantages of large particle size and uneven distribution of the drug, it is difficult to greatly increase the dissolution rate of the drug, the preparation process is complicated, and the production cost is high.
