Abstract
Description
本発明は、不快味を呈する薬物を含有する固形製剤に関する。 The present invention relates to a solid preparation containing a drug exhibiting an unpleasant taste.
イブプロフェン等の刺激性苦味を有する薬物を、散剤や顆粒剤のような粒子径が小さく比表面積が大きい製剤に配合した場合、錠剤の場合と比較して薬物の苦味がより強く感じられる。そこで、これらの製剤の服用性向上の観点から、例えば、特開平９−２０８４５８号公報に、薬物及び組成物中３０重量％以上の水膨潤性物質を含有する組成物を水又は含水アルコールで湿式造粒することにより薬物の不快味をマスキングした経口用製剤が記載されている（特許文献１参照）。 When a drug having an irritating bitter taste such as ibuprofen is blended in a preparation having a small particle size and a large specific surface area such as a powder or granule, the bitter taste of the drug is felt stronger than in the case of a tablet. Therefore, from the viewpoint of improving the dosage of these preparations, for example, in JP-A-9-208458, a composition containing 30% by weight or more of a water-swellable substance in a drug and a composition is wet with water or hydrous alcohol. An oral preparation in which the unpleasant taste of a drug is masked by granulation is described (see Patent Document 1).
また、特表２００３−５０４３２４号公報には、不快な味を有する活性成分と顆粒崩壊剤を含む顆粒に、被覆剤と膜崩壊剤を含む懸濁液を噴霧して被覆することにより不快味をマスキングした顆粒剤が記載されている（特許文献２参照）。しかしながら、この技術では溶出性を改善しようとすると、不快味のマスキングは十分に図れず、一方、十分な不快味のマスキングを図ろうとするとコーティング層を厚くする必要があり、結果として溶出が遅くなるという問題があった。 Also, Japanese Patent Publication No. 2003-504324 discloses an unpleasant taste by spraying a granule containing an active ingredient having an unpleasant taste and a granule disintegrating agent by spraying a suspension containing a coating agent and a membrane disintegrating agent. A masked granule is described (see Patent Document 2). However, this technique cannot sufficiently mask the unpleasant taste if it is intended to improve the dissolution property, but if it is intended to sufficiently mask the unpleasant taste, it is necessary to increase the thickness of the coating layer, resulting in a slow dissolution. There was a problem.
そこで、薬物の溶出性と不快味のマスキングの両方を満足する製剤を得るためには、コーティング剤に配合される成分の選定が重要となっている。例えば、コーティング剤に水不溶性高分子を配合することにより不快味のマスキングを実現し、水溶性高分子を配合することにより溶出性を確保することができる。また、フィルムコーティングにおいては、皮膜量を少なくし、コーティング効率を高める目的で、核粒子に直接被覆される一次皮膜（アンダーコート層）と、アンダーコート層の上に被覆される皮膜（オーバーコート層）の２層のコーティングが施されることがある。 Therefore, in order to obtain a preparation satisfying both drug dissolution and masking of unpleasant taste, selection of components to be blended in the coating agent is important. For example, unpleasant taste masking can be realized by adding a water-insoluble polymer to the coating agent, and elution can be ensured by adding a water-soluble polymer. In film coating, the primary coating (undercoat layer) directly coated on the core particles and the coating (overcoat layer) coated on the undercoat layer for the purpose of reducing the coating amount and increasing the coating efficiency. ) May be applied in two layers.
しかしながら、オーバーコート層のコーティング剤中の水不溶性高分子の配合量が増加すると不快味のマスキング効果は増強するが薬物の溶出が遅くなり、一方、水溶性高分子の配合量が増加すると薬物の溶出は速くなるが不快味のマスキングが不十分となるという問題があった。 However, increasing the amount of water-insoluble polymer in the coating agent of the overcoat layer enhances the masking effect of unpleasant taste but slows the elution of the drug, while increasing the amount of water-soluble polymer increases the drug content. There was a problem that elution was faster but masking of unpleasant taste was insufficient.
よって、本発明の目的は、イブプロフェン等の不快味を呈する薬物を含有し、薬物の不快味が十分にマスキングされ、且つ溶出性が改善された製剤粒子を提供することである。 Accordingly, an object of the present invention is to provide a preparation particle containing a drug exhibiting an unpleasant taste such as ibuprofen, sufficiently masking the unpleasant taste of the drug and having improved dissolution property.
上記課題を解決するために、本発明者らは、鋭意検討を重ねた結果、苦味薬物を含有する核粒子を調製し、水溶性高分子及び少量で薬物の溶出を促進する物質（以下、溶出促進剤とする）を配合したコーティング剤を用いてアンダーコートを施し、さらに、水溶性高分子、水不溶性高分子、及び、溶出促進剤を配合したコーティング剤を用いてオーバーコートを施すことにより、薬物の不快味のマスキングと溶出性が同時に改善される製剤粒子が得られることを見出した。さらに溶出促進剤の選定を鋭意検討した結果、溶出促進剤として、散剤、顆粒剤、錠剤等に配合した場合にこれらの製剤の崩壊性を高めることによって薬物の溶出性を高める性質を有する物質等を用いることにより、さらに不快味が十分にマスキングされ、且つ溶出が速い製剤粒子が得られることを見出し、本発明を完成した。 In order to solve the above-mentioned problems, the present inventors have conducted intensive studies and prepared core particles containing a bitter drug, and a water-soluble polymer and a substance that promotes drug elution with a small amount (hereinafter, elution). By applying an undercoat using a coating agent blended with an accelerator), and further applying an overcoat using a coating agent blended with a water-soluble polymer, a water-insoluble polymer, and an elution accelerator, It has been found that pharmaceutical particles can be obtained in which masking of the unpleasant taste of the drug and dissolution are improved at the same time. Furthermore, as a result of earnest examination of the selection of dissolution enhancers, substances that have the property of enhancing the dissolution properties of drugs by increasing the disintegration properties of these preparations when incorporated in powders, granules, tablets, etc. as dissolution enhancers It was found that by using this, it is possible to obtain formulation particles that are sufficiently masked of unpleasant taste and that are rapidly eluted, thereby completing the present invention.

本発明の製剤粒子は、核粒子にアンダーコート層を被覆することにより、その上のオーバーコート層を薄く均一に被覆することができることから、従来のフィルムコーティングと比較して被覆量を少なくすることができる。これにより、従来のコーティング製剤と比較して粒子径を大きくすることなく、不快味のマスキングを確保することができる。核粒子に対するアンダーコート層及びオーバーコート層の割合は、核粒子の質量に対して、アンダーコート層が1〜10質量％、オーバーコート層が5〜20質量％である。 In the preparation particles of the present invention, by coating the undercoat layer on the core particles, the overcoat layer thereon can be thinly and uniformly coated, so that the coating amount can be reduced compared with the conventional film coating. Can do. Thereby, masking of an unpleasant taste can be ensured, without enlarging a particle diameter compared with the conventional coating formulation. The ratio of the undercoat layer and the overcoat layer to the core particles is 1 to 10% by mass for the undercoat layer and 5 to 20% by mass for the overcoat layer with respect to the mass of the core particles.
また、前記核粒子を前記コーティング層でコーティングする方法としては、一般的な方法を用いることができ、例えば、流動層コーティング法、転動流動層コーティング法、転動流動コーティング法、パンコーティング法等が挙げられる。 In addition, as a method of coating the core particles with the coating layer, a general method can be used, for example, a fluidized bed coating method, a rolling fluidized bed coating method, a rolling fluidized coating method, a pan coating method, or the like. Is mentioned.
本発明の製剤粒子は、さらに賦形剤あるいは他の成分と混合した後に、常法により各種固形製剤に調製することができる。各種固形製剤としては、例えば、顆粒剤、散剤、丸剤、錠剤、カプセル剤を挙げることができる。 The preparation particles of the present invention can be prepared into various solid preparations by a conventional method after further mixing with an excipient or other components. Examples of various solid preparations include granules, powders, pills, tablets, and capsules.
