AMORPHOUS FORM OF HETEROCYCLIC COMPOUND, SOLID DISPERSION AND PHARMACEUTICAL PREPARATION EACH COMPRISING THE SAME, AND PROCESS FOR PRODUCTION OF THE SAME

摘要

[PROBLEMS] The object is to improve the absorbability of a heterocycliccompoundincluding s-triazine and a pyrimidine derivative in vitro. [MEANS FOR SOLVINGPROBLEMS]Disclosed is, for example, an amorphous form of a heterocyclic compound asrepresented by thegeneral formula (I) [wherein each of R's and others is as defined in thedescription] includings-triazine and a pyrimidine derivative, or a hydrate, a solvate or apharmaceutically acceptable saltof the heterocyclic compound. Also disclosed is a process for producing theamorphous form.Further disclosed are: a solid dispersion comprising the amorphous body; and amedicinalpreparation comprising the solid dispersion.(see formula I)
