    • A composition containing a poorly water soluble substance of the present invention is a composition having a median diameter of not more than 1 μm, comprising (i) a poorly water soluble substance and (ii) polyvinylpyrrolidone or a vinylpyrrolidone-vinyl acetate copolymer, and preferably, a composition having a median diameter of not more than 1 μm, comprising (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.A composition containing a poorly water soluble substance of the present invention can be prepared into a solid dosage form for oral administration in various forms such as tablet, powder, granule, capsule and the like. Therefore, using a composition containing a poorly water soluble substance of the present invention, for example, pharmaceutical preparations in various dosage forms showing good absorbability of a drug, which is a poorly water soluble substance, can be realized.
