イコチニブ塩酸塩及びイコチニブのフォームIIの薬物動態試験
薬物及び試薬:本試験で使用されるイコチニブ塩酸塩は、国際公開第2010/003313号により開示の結晶形Iであった。イコチニブのフォームII及びイコチニブ塩酸塩は微粒子に粉砕したものであった。物質含有量(純度)は99.0%以上であった。カルボキシメチルセルロースナトリウムは、医薬品等級のものであった。
実験動物:SDラットを、イコチニブ塩酸塩群とフォームII群とに分けた。
製剤:各化合物の量を秤量した後、カルボキシメチルセルロースナトリウムを、試験化合物の濃度が0.5%になるように添加した。次いで、固体混合物を水中での最終濃度10mg/mlで添加し、その懸濁液を調製した。
投与及び試料収集:5ml/kgの用量体積中イコチニブが50mg/kgに相当する用量で各懸濁液を絶食SDラットに経口投与した。血液0.4mlを、試験化合物の投与後0.5、1、1.5、2、4、6、8及び24時間ごとにEDTA−K入り抗凝固管に採取し、3000rpmで10分間遠心分離し、120μLの血漿を収集し、冷蔵で保存した。
高速液体クロマトグラフィーにより試料を分析した。クロマトグラフィー条件には、固定相としてC18シラン結合シリカと、移動相としてアセトニトリル中リン酸二水素ナトリウムを0.02mol/L(40:60、水酸化ナトリウム溶液を使ってpHを5.0まで調節)と、334nmの検出波長とを利用した。イコチニブのフォームIIとイコチニブ塩酸塩の結晶形IとのPKプロファイルの比較を表1及び図5にまとめた。イコチニブのフォームIIはイコチニブ塩酸塩の結晶形Iよりも高い生物学的利用能を示した。
硬ゼラチンカプセル製剤化
経口組成物の特定の実施態様として、実施例1−11の多形約100mgは、総量約580mgから約590mgとなってサイズ0の硬ゼラチンカプセルに詰めるために十分に微粉化されたラクトースを用いて製剤化される。
