Description
特許文献2は、1つが単層のコーティング剤でコーティングされた徐放成分であり、他方が2層のコーティング剤でコーティングされた徐放成分であり、異なった徐放成分から調製された経口製剤を開示する。その方法に従って調製された錠剤やカプセルの放出率は、十分に穏やかではなく、放出量も一定ではない。その技術的解決法は、現存する問題、即ち、薬物適用の回数を減らし、患者の血漿濃度の変動を小さくし、薬物バイオアベイラビリティを増して、薬物療法中の副作用を減らすということを解決することはできない。
アプレミラストの10-20重量% が、2 時間後に放出され、
アプレミラストの30-60重量%が、 4時間後に放出され、
アプレミラストの85-96重量% が、8時間後に放出され、そして
アプレミラストの96-100重量%が、12時間後に放出される。
本発明の量と溶解率の数値は不可避の実験誤差を有しており、誤差値は±1%である。
1.血漿濃度を長時間に亘って維持することができ、それにより通常製剤の高頻度の投与のピーク‐谷現象を回避でき;一方、薬物のバイオアベイラビリティが増加して、薬物適用中の胃腸管に対するアプレミラストの副作用が減少する。
2.作用時間が異なった薬物放出メカニズムによって延長されて、投与頻度が減り、そして患者のコンプライアンスを改善する。
本発明を以下の実施例により更に詳細に説明する。これらの実施例は説明するためだけのものであり、本発明の範囲を限定するものではない。
アプレミラスト、フィラー、徐放性物質、界面活性剤、流動化剤、および滑沢剤を表1の比率に従って混合し、次いで粉末直接打錠技術を用いて直接圧縮して錠剤にした。打錠に際して、2 mm〜6 mmの直径を持つ円形のダイなど、どの直径のダイも選択できる。錠剤の重量は、10 mg〜100 mgであった。
アプレミラスト、フィラー、徐放性物質、界面活性剤、流動化剤、および滑沢剤を表2の比率に従って混合し、次いで粉末直接打錠技術を用いて直接圧縮して錠剤にした。圧縮した錠剤は、次いで高度に有効なコーティング剤でコーティングする。打錠に際して、2 mm〜6 mmの直径を持つ円形のダイなど、どの直径のダイも選択できる。錠剤の重量は、10 mg〜100 mgであった。
徐放性成分Iおよび部位特異的放出成分IIを異なる比率で00#カプセルに充填して、異なる溶解プロフィールを有する徐放性製剤を調製した。具体的実施態様を表3に示す。
きする効果を確実にすることができる。
