Abstract
Provided are a solid preparation which rapidly disintegrates in the oral cavity when taken together with the saliva in the oral cavity or a small amount of water, can be prepared easily and has strength enough to retain its formability upon production or during distribution; and a production process of the solid preparation. Specifically, provided are a solid preparation comprising a low-substituted hydroxypropyl cellulose having a loose bulk density of 0.40 g/ml or greater and a tapped bulk density of 0.60 g/ml or greater, and a sugar and/or sugar alcohol; and a production process of the solid preparation. Also provided are a solid preparation comprising a low-substituted hydroxypropyl cellulose having a volume-average particle size as measured by the dry laser diffraction method of 25 &mgr;m or less which is obtained by pulverizing a low-substituted hydroxypropyl cellulose having a loose bulk density of 0.40 g/ml or greater, a tapped bulk density of 0.60 g/ml or greater, and a volume average particle size of 30 &mgr;m or greater—and a sugar and/or sugar alcohol; and a production process of the solid preparation.
