すなわち、本発明は以下の通りである。
(1)1種以上の活性成分と1種以上の溶出制御基剤とを含有し、圧縮成形により得られる固形製剤であって、前記溶出制御基剤は、保水量が400%以上であり、ゲル押込み荷重値が200g以上であり、水溶性成分量が40〜95重量%であり、目開き75μmの篩いを通過する粒子が90重量%以上であり、目開き32μmの篩いを通過する粒子が20重量%以上であり、かつ平均粒径が20μm以上50μm未満の加工澱粉を5.0重量%以上99.9%重量%以下の範囲で含む、徐放性固形製剤。(2)前記加工澱粉が、目開き75μmの篩いを通過する粒子が98重量%以上、目開き32μmの篩いを通過する粒子が40重量%以上である、(1)に記載の固形製剤。(3)前記加工澱粉の膨潤度が6cm/g以上10cm/g以下である、(1)又は(2)に記載の固形製剤。(4)前記加工澱粉が、安息角45°以下であり、かつ見かけ比容積が1.4cm/g以上3.6cm/g以下である、(1)〜(3)のいずれかに記載の固形製剤。(5)前記溶出制御基剤がさらに親水性高分子助剤を含み、かつ、前記加工澱粉と親水性高分子助剤との重量配合比率が、50:50〜99.9:0.1の範囲内である、(1)〜(4)のいずれかに記載の固形製剤。
That is, the present invention is as follows.
(1) A solid preparation containing one or more active ingredients and one or more elution control bases and obtained by compression molding, wherein the elution control base has a water retention amount of 400% or more, The gel indentation load value is 200 g or more, 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 are 90% by weight or more, and the particles passing through the sieve having an opening of 32 μm A sustained-release solid preparation comprising 20% by weight or more of processed starch having an average particle size of 20 μm or more and less than 50 μm in a range of 5.0% by weight or more and 99.9% by weight or less. (2) The solid preparation according to (1), wherein the processed starch has 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. (3) The solid preparation according to (1) or (2), wherein the degree of swelling of the processed starch is 6 cm 3 / g or more and 10 cm 3 / g or less. (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 any one of (1) to (3). Solid formulation. (5) The elution control base further contains a hydrophilic polymer aid, and the weight blending ratio of the processed starch and the hydrophilic polymer aid is 50:50 to 99.9: 0.1. The solid preparation according to any one of (1) to (4), which is within a range.

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。 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.

本発明の固形製剤は、1製剤あたりの重量が0.20g以上であることが好ましい。これにより、溶出後期の溶出速度を減少させることなく溶出時間を簡単に延長することが可能となる。これは、固形製剤の圧縮方向の膨潤度、及び、膨潤度比が一定範囲にある場合には、固形製剤の形状を大きくしても活性成分の溶出性には影響を及ぼさないことによる。ちなみに、例えばヒドロキシプロピルメチルセルロース等の溶出制御基剤を用いて、圧縮方向の膨潤度又は膨潤度比が上記の好ましい範囲にない例では、固形製剤の重量が大きくなると溶出後期の溶出速度が減少してしまうので好ましくない。固形製剤の圧縮方向の膨潤度、及び、膨潤度比が一定範囲にある場合には、活性成分の溶出性を維持したまま、単純に固形製剤の重量を大きくすることで活性成分の溶出時間を延長することが可能となる。 The solid preparation of the present invention preferably has a weight per preparation of 0.20 g or more. This makes it possible to easily extend the elution time without reducing the elution rate in the later stage of elution. This is because when the degree of swelling in the compression direction of the solid preparation and the swelling ratio are within a certain range, the dissolution of the active ingredient is not affected even if the shape of the solid preparation is increased. By the way, in the case where the elution control base such as hydroxypropylmethylcellulose is used and the swelling degree or swelling ratio in the compression direction is not within the above preferred range, the elution rate in the later stage of elution decreases as the weight of the solid preparation increases. This is not preferable. If the swelling degree and the swelling ratio of the solid preparation are within a certain range, the dissolution time of the active ingredient can be increased by simply increasing the weight of the solid preparation while maintaining the dissolution of the active ingredient. It can be extended .

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.
