Abstract:
The present invention provides a novel base material for a dry solid dispersion, a solid dispersion containing the base material, and a composition containing the dispersion; the solid dispersion of the present invention, which contains a poorly soluble component with improved dissolvability, can be obtained by mixing a polyvinyl alcohol-based copolymer, as a base material for the dry solid dispersion, with a poorly soluble component, and then heating it.
