摘要

[PROBLEMS] The object is to improve the resorbability of a heterocyclic compound including s-triazine and a pyrimidine derivative in vitro. [MEANS FOR SOLVING PROBLEMS] Disclosed is, for example, an amorphous form of a heterocyclic compound as represented by the general formula (I) [wherein each of R's and others are as defined in the description] and including s-triazine and a pyrimidine derivative, or a hydrate, a solvate or a pharmaceutically acceptable salt of the heterocyclic compound. Also disclosed is a process for producing the amorphous form. Further disclosed are: a solid dispersion comprising the amorphous form; and a medicinal preparation comprising the solid dispersion.
