The amount of the water-soluble component is 40 to 95% by weight, the particles passing through the sieve having an opening of 75 μm is 90% by weight or more, the particles passing through the sieve having an opening of 32 μm is 20% by weight, and the average particle size is 20 μm. And processed starch having a disintegration time of 8 hours or more, an indentation strength of 2 kg or more, and a hydrophobic assistant having a sedimentation volume of 3 ml or less when dispersed in water, and A solid preparation, wherein a weight blending ratio of the processed starch and the hydrophobic auxiliary agent is in the range of 50:50 to 99: 1. (2) In the processed starch, 98% by weight or more of particles passing through a sieve having an opening of 75 μm, and 40% by weight or more of particles passing through a sieve having an opening of 32 μm. Solid formulation. (3) The solid preparation according to (1) or (2), wherein the degree of swelling of the processed starch is from 6 cm 3 / g to 10 cm 3 / g. (4) The processed starch has an angle of repose of 45 ° or less and an apparent specific volume of 1.4 cm 3 / g or more and 3.6 cm 3 / g or less, according to (1) to (3) The solid formulation in any one. (5) The solid preparation according to any one of (1) to (4), wherein the content of the one or more active ingredients is 20 to 70% by weight.

また、特定の加工澱粉は、安息角が45°以下であることが好ましい。好ましくは安息角が43°以下である。また、特定の加工澱粉は見かけ比容積が1.4cm/g以上3.6cm/g以下であることが好ましい。安息角が45°以下で、かつ見かけ比容積が1.4〜3.6cm/gの範囲にある加工澱粉は、活性成分との混合性・分散性に優れるため、均一なゲルマトリクスを形成することができ、安定な徐放性としやすいので好ましい。 Further, the specific processed starch preferably has an angle of repose of 45 ° or less. The angle of repose is preferably 43 ° or less. The specific processed starch preferably has an apparent specific volume of 1.4 cm 3 / g or more and 3.6 cm 3 / g or less. Processed starch with an angle of repose of 45 ° or less and an apparent specific volume in the range of 1.4 to 3.6 cm 3 / g is excellent in mixing and dispersibility with the active ingredient, and forms a uniform gel matrix. It is preferable because it is easy to achieve stable sustained release.

目開き75μmの篩いを通過する粒子が90重量%以上、目開き32μmの篩いを通過する粒子が20重量%以上、且つ平均粒径が20μm以上50μm未満となるように粒度調整された、保水量が400%以上、ゲル押込み荷重が200g以上、水溶性成分量が40〜95重量%の加工澱粉は、粒度未調整のものに比べて膨潤度が小さく、ゲル押込み荷重値が高いのが特徴である。また、加工澱粉は、見かけ比容積が1.4〜3.6cm/gの範囲にあることが好ましいが、該加工澱粉の見かけ比容積は、乾燥工程における液濃度の大小にも影響され、また、スプレードライ乾燥工程においてアトマイザーの回転数にも影響される。そのため、見かけ比容積を上記の好ましい範囲とするには、これらを適宜調整すればよい。 Water retention amount adjusted so that particles passing through a sieve having a mesh opening of 75 μm are 90% by weight or more, particles passing through a sieve having a mesh opening of 32 μm are 20% by weight or more, and the average particle size is 20 μm or more and less than 50 μm. Processed starch having a gel indentation load of 200 g or more and a water-soluble component amount of 40 to 95% by weight is characterized by having a lower degree of swelling and a higher gel indentation load value than those having no adjusted particle size. is there. Furthermore, modified starch, it is preferable that the apparent specific volume is in the range of 1.4~3.6cm 3 / g, apparent specific volume of the processed starch is also affected by the magnitude of the liquid concentration in the drying step, Moreover, it is influenced also by the rotation speed of an atomizer in a spray dry drying process. Therefore, in order to make the apparent specific volume within the above preferable range, these may be appropriately adjusted.

(6)見かけ比容積(cm /g)
Obtained using a Sugihara-type angle of repose measuring instrument (Pharmacology 27, p.260, 1965).
(6) Apparent specific volume (cm 3 / g)

スコットボリュームメーター(筒井理化学機器株式会社)を用いて測定する。粉体試料を定量フィーダーを用いて2−3分かけて測定容器内に粉体があふれるまで流下させる。次いで容器の上部に堆積した過剰量の粉体をすり落とし、また、容器の側面に付着した試料を除去する。その後、容器に疎充填された粉体重量を量る。測定容器の容積を容器に疎充填された粉体重量で除した値を見かけ比容積とする。
(7)保水量
Measured using a Scott volume meter (Tsutsui Rikenki Co., Ltd.). The powder sample is allowed to flow down for 2-3 minutes using a quantitative feeder until the powder overflows into the measurement container. Next, an excessive amount of powder deposited on the top of the container is scraped off, and the sample adhering to the side surface of the container is removed. Thereafter, the weight of the powder loosely filled in the container is measured. An apparent specific volume is obtained by dividing the volume of the measurement container by the weight of the powder loosely filled in the container.
(7) Water retention amount
