Description
この問題の解決策は、特に薄いポリマー系フィルムから成る特定のタイプの経粘膜投与システムを用いて得られたデータに基づく本発明において提供される。このシステムは、口腔粘膜に付着したとき、活性成分を直接、粘膜に、または部分的に口腔内の唾液中に、食道(espphagus)に、および胃に放出する。活性成分は、口腔、食道および胃において、主に粘膜を介して吸収されることから、従来の経口投与および消化管吸収後に観察される初回通過代謝が回避される。この剤形は、口腔ウエハとも記載される。
イデベノン;化学名:2-(10-ヒドロキシデシル)-5,6-ジメトキシ-3-メチル-2,5-シクロヘキサジエン-1,4-ジオン;化学情報検索サービス機関(CAS)登録番号:58186-27-9)およびそれらの類似体の、口腔粘膜に付着したとき、粘膜もしくは部分的に口腔内の唾液中へ活性成分を直接放出する、好ましくは薄いフィルム製剤(口腔ウエハとも称する)の製造のための、および、ヒトもしくは動物への経粘膜投与のために使用される、使用に関する。このようなシステムにより、経口経路での投与と比較して、化合物の非常に高い血漿レベルが得られる。活性成分のイデベノンと添加剤および添加剤とを含む薄いフィルム(口腔ウエハ)製剤としての薬学的に活性な成分のための好適な経粘膜投与システムならびにこの種の製剤に用いるのに適した製造プロセスを、本明細書でさらに記載する。
るかに高い血漿レベルを達成させる可能性が開かれる。
a)投与に必要な用量を大幅に低減させながら、同様に高い活性成分の血漿レベルが得られる。活性成分の曝露量が少ないことは、有害な副作用のリスクを低減することに関係すると一般に考えられており、また患者のコンプライアンスの改善につながるという医学的利点が提供される。イデベノンでの特定のケースでは、記述した胃腸での副作用が回避され得る。
b)胃腸経路を介して活性成分が吸収される経口製剤で達成されるレベルと比較して、非常に高い血漿レベル。血漿レベルが高いことにより、例えば、血液脳関門を通過するためには高用量を必要とする神経筋疾患分野のさらなる適応症に、イデベノンの使用を拡張し得る。
c)フィルム製剤(口腔ウエハ)は薄く、取扱いが容易であり、1単位でいくつかの大きな錠剤の嚥下に代わり得ることから、患者の利便性が増加する。
d)嚥下障害を有する患者(例えば、ある種の神経筋疾患を有する患者または8歳未満の小児患者)への薄いフィルム製剤(口腔ウエハ)の投与により、服薬遵守および使用の利便性が増加する。
1,4-ベンゾキノン)3~20質量%、特に好ましくは5~10質量%と、担体材料(特に適切に置換されている炭水化物または他の水溶性ポリマー)80~97質量%、好ましくは90~95質量%とを含むことが好ましい。
神経変性疾患、好ましくは、フリードライヒ運動失調(FRDA)、筋萎縮性側索硬化症(ALS)、パーキンソン病、アルツハイマー病、ハンチントン舞踏病、脳卒中/再灌流障害および認知症から成る群から選択される神経変性疾患;
神経筋疾患、好ましくは、デュシェンヌ型筋ジストロフィー(DMD)、ベッカー型筋ジストロフィー(BMD)、肢帯筋異栄養症(Limb-Girdle muscular dystrophy、LGMD)、X連鎖性拡張型心筋症(X-linked dilated cardiomyopathy、XLDCM)、パントテン酸キナーゼ関連神経変性症(PKAN)、脊髄筋萎縮症(SMA)、多発性硬化症、再発寛解型多発性硬化症(relapsing remitting multiple sclerosis、RR-MS)、一次進行性多発性硬化症(primary progressive
multiple sclerosis、PP-MS)、二次進行性多発性硬化症(secondary progressive multiple sclerose、SP-MS)、クーゲルバーグ-ヴェランダー病、およびウェルドニッヒ-ホフマン病から成る群から選択される神経筋疾患;
精神疾患、好ましくは、統合失調症、大鬱病性障害、双極性障害および癲癇から成る群から選択される精神疾患;
代謝性障害、好ましくは、加齢関連身体機能低下、肥満、体重過多、II型糖尿病、およびメタボリック症候群から成る群から選択される代謝性障害;
癌;多発性硬化症;または
免役機能不全、好ましくは、関節炎、乾癬および慢性関節リウマチから成る群から選択される免疫機能不全
の処置に使用される。
択される。
もよい。
112gのPVAを720mLの水に添加し、完全に溶解するまで撹拌した。適切であれば、加熱して溶解を促進させた。冷却後、140gのイデベノンを均一に分散させた。その後、28gのCMCを添加し、完全に溶解するまで、混合物を撹拌した。混合物を、脱気し、コーティングした後、乾燥させた。50~150μmの厚さの薄い不透明なフィルムを作製した。サンプルを適当な大きさに切断することによって、30mgのイデベノンを含有する不透明なウエハを得た。
28gのイデベノンを720mLの75:25のメタノール:水に添加し、活性成分が完全に溶解するまで撹拌した。250gのHPMCを加え、完全に溶解するまで撹拌した。混合物を脱気させ、コーティングした後、乾燥させた。厚さ100~300μmの薄い透明なフィルムを作製した。サンプルを適当な大きさに切断することによって、15mgのイデベノンを含有する透明なウエハを得た。
イデベノンの口腔粘膜送達後の薬物動態学的データ
口腔粘膜経路を介して投与される2つの異なる薄いフィルム製剤(口腔ウエハ)を適用後、イデベノンの血漿レベルを調べ、経口経路(胃管栄養)によりイデベノンをマイクロエマルジョンで投与した場合に得られるプロファイルと比較した。この研究で使用した用量は、30mgの口腔粘膜(口腔ウエハA、懸濁液型)、15mgの口腔粘膜(口腔ウエハB、固溶体型)、および300mgの経口(経口胃管栄養によって投与されるTPGS/Miglyolマイクロエマルジョン)であった。研究は、3元交差試験であり、各投与間で1週間の休薬(wash-out)を設けた。製剤は、絶食条件下の雌のビーグル犬に投与した。遊離の(抱合していない)イデベノン、およびその全代謝産物(全イデベノン、全QS10、全QS6および全QS4)の薬物動態学的曝露を製剤ごとに測定した。
・固溶体技術に基づく薄いフィルム製剤(口腔ウエハ)によるイデベノンの口腔粘膜投与により、イデベノンの相対的バイオアベイラビリティーが、経口投与に対して約100
倍大きくなり、顕著に改善される。バイオアベイラビリティーが増加した主な理由は、初回腸肝循環が迂回されたためである。
・特に、このウエハからのイデベノンの吸収が、イデベノンの胃管栄養による経口投与と比較して増加しているという証拠がある。
・微粒子懸濁技術に基づくウエハも、より程度は少ないが、イデベノンの相対的バイオアベイラビリティーを改善する。
・イデベノンの代謝スペクトルは、胃管栄養による経口投与後と口腔粘膜適用後とで同程度である。
・口腔ウエハ製剤により、経口経路を介して投与される製剤を上回る以下の利点が得られる:
・用量の顕著な減少(副作用の低減)
・より高い血漿レベルが達成可能
・患者の利便性の増加
・嚥下困難な患者へ投与可能
・本発明のシステムは、さらにポリマーマトリックスを含むことができ、該ポリマーマトリックスに、薬学的活性成分を、懸濁液、微粒子懸濁液、エマルジョン、マイクロもしくはナノエマルジョン、または溶解されたおよび/もしくは分子分散された形態で組み込むことができる。
