Description
本発明は、経口投薬用制御性放出製剤、およびそれを使用して対象の様々な病状を治療する方法に関する。従って、本発明は、化学、薬学、医学、およびその他の健康科学の分野に関する。
従って、本発明は、特定の組成物と組み合わされた際に、その内部に含まれる活性薬剤の放出特性に影響を与える幾何学的構造を有する薬物錠剤を提供する。一態様では、経口投薬用徐放性薬物錠剤は、第1の活性薬剤を有する第1の層を含んでよく、第1の層は2つの隣接する制御性放出層の間に配置され、その隣接する層の少なくとも1つは、少なくとも1つの第2の活性薬剤を含む。2つの隣接する層は、それらが第1の層の一部を覆うように配置される。経口用剤形の全体の構造および幾何学的設計に応じて、2つの隣接する層は分離した層であってよく、または単一の連続層につながっていてもよい。いくつかの態様では、これらの幾何学的に構造が決定された薬物錠剤は、第1および/または第2の活性薬剤部分の有無にかかわらず、機能性高分子および/または非機能性高分子を使用してさらにコーティングされうる。
本発明を説明し特許請求を行う上で、下記で説明される定義に従って以下の専門用語が使用される。
本発明は、そのうちの少なくとも1つが、延長されたまたは持続した時間にわたって投与される、2つ以上の活性薬剤を投与するための経口用剤形を含む。いくつかの態様では、そのような経口用剤形は、異なる活性薬剤を含む複数の薬物層を有してよい。経口用剤形のある薬物層からのある活性薬剤の放出速度は、消化管の水性環境に曝露される薬物層の表面積の割合に依存する場合が多い。このことは、水性環境によってマトリックスが膨潤する(すなわち水和する)および侵食されるのに伴って活性薬剤が放出される、膨潤性/侵食性のマトリックスを有する薬物層に特に当てはまる。薬物層の表面積の一部の消化管環境への曝露を、例えば別の薬物を含む層でそれを覆うことによって物理的に制御することで、覆われた層の侵食および/または膨潤速度が制御されてよく、結果として、その内部に含まれる薬物の放出が制御されてよい。換言すれば、覆われた層に含まれる薬物の放出速度は、その層の露出表面積の量に比例する。従って、露出表面積の量が一定のままならば、覆われた層からの薬物の放出速度は比較的一定のままである。故に、薬物を含有する層の露出表面積を制御することによって、薬物の放出速度が制御されてよい。1つまたは複数の制御層が膨潤するにつれて、水和した層に含まれる薬物の拡散が増加し、放出のための表面積が増加し、層が侵食されるのに従って薬物の拡散距離が減少する。さらに侵食されると、その時点では水性環境に直接曝露されている薬物層の表面積も同様に効果的に増大する。このようにして、これらの複合効果が、覆われた層に含まれる活性薬剤の放出を増加させてよい。隣接する層に含まれる任意の第2の活性薬剤は、下にある薬物層の大部分が露出する前および露出中に放出され、こうして効果的な併用療法が達成されうる。
以下は、10/500mgヒドロコドン酒石酸水素塩/アセトアミノフェン錠の処方例である。下記に例示される各部分は個別に処方され、図1に示す構造を有する単一の三層錠に圧縮される。錠剤は、2つの持続放出性アセトアミノフェン層の間に配置される持続放出性ヒドロコドン層を含む。
以下は、図2に示す構造を有する、15/500mgヒドロコドン酒石酸水素塩/アセトアミノフェン持続放出錠の処方例である。実施例1の10/500mgヒドロコドン酒石酸水素塩/アセトアミノフェン持続放出錠は、表3に示す即時放出性ヒドロコドン酒石酸水素塩コーティングでコーティングされた。
