Title
(JA) 医薬投与形態
Abstract
(JA)

医薬活性剤放出用のpH応答性および粘膜付着性の医薬投与形態が記載される。この投与形態は、部位特異的な粘膜付着のための粘膜付着層、非水溶性外層、および部位特異的な送達のための1以上の医薬活性剤を含む中間層を含む。異なる膜層は、特定の期間および特定の薬物放出パターンで特定の部位に薬物を送達できる薬物送達システムを創製するための異なる機能を果たす。投与形態は、各層が活性剤を含む2以上の中間層を有することができる。また、粘膜付着層は、活性剤を含むことができる。投与形態は、好ましくは胃腸管への活性剤放出用の経口またはバッカル送達形態である。中間層は、活性剤を含有する電界紡糸ファイバー膜層であることができる。
