Description
本発明の方法の有利な実施形態は、従属請求項の方法に定義される。
本発明によると、押し出しにより製造された医薬の剤形を使用する方法が示唆されている。より具体的には、錠剤化用及びカプセル充填用の粒状物を製造するため、及び直接錠剤化するためのアジュバントとして射出成形技術を使用して更に加工するための少なくともいずれかのために医薬の剤形を使用する方法であって、前記剤形は、押し出しによって特性が形成される基剤であって、基本的な成分としてデンプン、デンプン誘導体、及びデンプン錯体のうちの少なくともいずれか1つを含有する基剤と、少なくとも1つの医薬の活性薬剤とを含み、前記剤形を押し出しによって形成して、前記基剤を非晶質または部分的に非晶質にすることにより、前記活性薬剤の放出が調節されており、かつ、前記剤形は、製剤に基づいて50重量%以下の少なくとも1つの医薬の活性薬剤をデンプン、デンプン誘導体、及びデンプン錯体のうちの少なくともいずれか1つと混合することにより乾燥製剤を形成する工程と、エクストルーダを用いて、オリフィスの温度が標準圧力下において100℃を超えない条件で前記乾燥製剤を押し出しして成形体を得ることにより基剤を形成する工程とを有する方法によって製造されたものであることを特徴とする方法が提供される。
更に、好ましい実施形態における本発明は、本発明による剤形が、多糖類として、デンプンまたはその誘導体、特に、非晶質または部分的に非晶質なデンプンまたはその誘導体を基剤中に含む方法に関連する。
特に好ましい実施形態によれば、本発明による剤形は、放出制御基材である。
本発明によれば、この目的は、活性薬剤が本質的に含有されている基剤を含む剤形であって、その本質的な特性は押し出し工程によって決定され、かつ、基剤の主要な成分として多糖類、及び/またはその誘導体、及び/またはその錯体、及び/または上記物質と他の物質の任意の混合物、及び/または糖類及び/またはその誘導体と、少なくとも1つの医薬として有効な物質とを含む剤形によって達成される。
親水性または両親媒性の固体、塩化ナトリウム及びラクトースのような水溶性物質、例えばラウリル硫酸ナトリウム及びシリカ(コロイド状に分散、かつ/またはキセロゲルとして)のような表面活性物質、
親水性または両親媒性の液体、例えばグリセリン及びポリエチレングリコールのようなポリグリコール類、例えばポリソルベートのような界面活性物質、
例えば、窒素、二酸化炭素のような気体が添加され得る。
本発明の方法によって実行された以下の例において、モデル活性薬剤としてカフェインが添加された様々な多糖類を使用した。押し出し実験は、ブラベンダー−1軸型スクリューエクストルーダ811201型(Brabender−Einschneckenextruder vom Typ811201)によって行った。この装置は、互いに独立して適温にされ得る(temperierbare)3つの部分、すなわち、供給領域とスクリュー領域とダイとを有する。22cmのスクリュー長、19mmのスクリュー径、16mmのコア径、及び15mmのピッチを有するコンベヤースクリューを圧縮することなく使用した。2.5〜7mmの異なる直径を有するダイを使用した。
示差走査熱量測定(DSC)によって、結晶性または部分的に結晶性デンプンの非晶質状態への転移を検知することが可能である。適当な押し出し条件下ではデンプンは完全にガラス化される、すなわち非晶質状態に変化する。例として、多糖類としてタピオカデンプンと、活性薬剤としてカフェインを用いた試験を行った。90%のタピオカデンプンと10%のカフェインからなり、水を添加した予備混合物の温度記録図を図1aに示す。図1aは約65°Cの範囲に典型的な吸熱ピークを示している。
上述したように、活性薬剤の放出全体の持続時間及び推移を調節することが可能である。このような方法で、非常に良好な水溶性活性薬剤のための「保存物」が得られるので、前述の例における24時間のような非常に長い活性薬剤放出時間は、新たな遅延原理の進歩という観点から有利なものと見なされる。活性薬剤の放出は、既に数回記載したように、多糖類または対応する誘導体及びそれらの混合物、対応するアジュバントの添加、及び/または押し出し工程パラメーターによって、選択的に影響を受け得る。
