Solid dosage form comprising solid dispersion and method for producing the same

摘要

Provided are a solid dosage form comprising a 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 a solid dispersion, the dispersion comprising: a poorly soluble drug, a water-soluble polymer and a disintegrant, wherein the disintegrant is low-substituted hydroxypropylcellulose having an average particle size of 10 to 100 µ m and a specific surface area measured by BET method of at least 1.0 m 2 /g. Moreover, provided is a method for producing a solid dosage form comprising a solid dispersion, the method comprising steps of: spraying a water-soluble 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 µm and a specific surface area measured by BET method of at least 1.0 m 2 /g and serving as a disintegrant and granulating the resultant; and drying.
