    摘要: Provided is an enteric-coated preparation comprising an enteric coating material capable of delivering a drug to a site within the small intestine in a site-specific manner. More specifically, provided is an enteric-coated preparation for delivering a drug to a site within the small intestine in a site-specific manner, comprising a drug-containing preparation and an enteric coating material which covers the preparation, wherein, in Dissolution Test as specified in the Japanese Pharmacopoeia Fourteenth Edition, no dissolution of the drug is observed in the Japanese Pharmacopoeia first fluid (pH 1.2) while dissolution of the drug is observed in the Japanese Pharmacopoeia second liquid (pH 6.8) 20 minutes or later from start of the Dissolution Test. The enteric coating material is preferably selected from the group consisting of hydroxypropylmethyl cellulose acetate succinate, hydroxypropylmethyl cellulose phthalate, methacrylic acid copolymer and carboxymethylethyl cellulose.

    摘要: Provided are a granule or a tablet of a solid dispersion that allows a drug in a preparation to be rapidly dissolved without impairing the dissolution of the solid dispersion, and a method for producing the same. More specifically, provided are a granule of a solid dispersion comprising a poorly soluble drug, a water-soluble polymer, an excipient and a disintegrator, wherein a content of the water-soluble polymer is 1 to 10% by weight and a content of the disintegrator is 15 to 50% by weight; a tablet of a solid dispersion comprising a poorly soluble drug, a water-soluble polymer, an excipient and a disintegrator, wherein a content of the water-soluble polymer is 1 to 5% by weight and a content of the disintegrator is 15 to 50% by weight; and a method for producing a granule or tablet of a solid dispersion comprising spraying a water-soluble polymer solution in which a poorly soluble drug has been dispersed or dissolved, on a mixed powder of an excipient and a disintegrator, and granulating and drying a resultant.
