    Abstract: The disclosed method involves preparation of a composition containing a poorly water soluble substance. The composition has a median diameter of not more than 1 ?m, and includes (i) a poorly water soluble substance, (ii) polyvinylpyrrolidone or a vinylpyrrolidone-vinyl acetate copolymer, and (iii) an auxiliary dispersion stabilizer. By employing such constitution, a poorly water soluble substance is sufficiently micronized and a composition containing a poorly water soluble substance showing good absorbability of the poorly water soluble substance can be provided.
