发明名称 Solid dosage form of enteric solid dispersion and method for producing the same
摘要 Provided are a solid dosage form comprising an enteric solid dispersion that allows a drug in the preparation to be rapidly dissolved without compromising the solubility of the solid dispersion, and a method for producing the same. More specifically, provided is a solid dosage form comprising an enteric solid dispersion comprising a poorly soluble drug, an enteric polymer and a disintegrant, wherein the disintegrant is low-substituted hydroxypropylcellulose having an average particle size of 10 to 100 mum and a specific surface area measured by BET method of at least 1.0 m<SUP>2</SUP>/g. Moreover, provided is a method for producing a solid dosage form comprising an enteric solid dispersion, the method comprising steps of: spraying an enteric polymer solution in which a poorly soluble drug has been dispersed or dissolved, on a powder of low-substituted hydroxypropylcellulose having an average particle size of 10 to 100 mum and a specific surface area measured by BET method of at least 1.0 m<SUP>2</SUP>/g and serving as a disintegrant; and granulating the resultant; and drying.
