実験の詳細
ここで製剤を製造するために使用された装置には:上置秤量器、ハンドスクリーン(12、14、16、18、パン、70メッシュ)、Rotapシーブシェーカー、IKAミキサー、KitchenAidフードプロセッサ(プレミリング)、Fitzミル(0.065インチスクリーン付き)、ジェットミル、Key International 高シェアミキサー、Glatt GPCC−3流動床乾燥機、Glatt GPCC−3流動床コーター(7インチWurster付き)、Karl Fischer水分分析器及び球状化装置である。
表1に示されるようにコア1は、前記のように次の設定を用いて製造された。湿式顆粒化設定は;インペラー速度300rpm、チョッパー速度3450rpm、湿塊物化時間80〜90秒、最大インペラー電力5.5〜6.2アンペア。押し出し設定は:インペラー速度25rpm、フィーダー速度30rpm、スクリーンサイズ1.2mm。押出物を、500pmで回転する球状化装置へ投入した。コア1粒子を17〜23℃で、45cfm空気流で、60〜75分間乾燥させた。
表1で示されるコア2は、前記のとおり、次の設定で製造された:湿式顆粒化設定は;インペラー速度640rpm、チョッパー速度9450rpm、最大インペラー電力6〜7アンペア。押し出し設定は:インペラー速度25rpm、フィーダー速度30rpm、スクリーンサイズ1.2mm。押出物を、900〜925pmで回転する球状化装置へ投入した。コア2粒子を17〜23℃で、45cfm空気流で、60〜75分間乾燥させた。
コア1及びコア2粒子をこれらのサイズに基づき分離した。14〜18メッシュサイズに入る分画をサブコーティングのために選択した。前記コアを、流動床乾燥機に投入し、10%ヒプロメロース(ヒプロメロースE5)水溶液の形のサブコーティング材料を前記コアに、室温でスプレーした。
評価された2つの腸溶性コーティング材料には、それぞれEudragit L30D−55及びKollicoat MAE 30 DPが含まれた。前記腸溶性コーティング材料は、溶液として、流動床コーター(7インチWurster)内で前記コアに適用された。表3および4は、それぞれ使用されたEudragitコーティング(腸溶性コーティングA)及びKollicoatコーティング(腸溶性コーティングB)を示す。
前製造した他粒子製剤は、望ましいUSO711腸溶性規格に合致又は近いかどうかを決定するために評価された。USP711腸溶性規格に合致するためには、0.1NのHCl養鶏中で2時間内に放出される活性成分は10%未満であることが必要である。続いて、pH6.8緩衝液(「緩衝段階」)中で85%以上の活性成分が45分間で放出されることが必要である。
