Abstract
Description
a)バッチ式操作で、所定の量の高分子結合剤、所定の量の活性成分、および、任意で所定の量の補助剤とを溶融容器に入れ、撹拌しながら高分子結合剤を溶融し、活性成分を高分子結合剤に分散させて、溶融状態の予備分散体を得る。
b)予備分散体を押出機に供給して、予備分散体を均質にし、ダイを通して溶融物を放出する。
c)溶融物を固化させる。
撹拌ユニットは、溶融容器の内容物を溶融容器内で撹拌、例えばかき混ぜられるように構成され、
変位要素は、内容物にとってアクセス可能な溶融容器の容積を減らすことにより、内容物を溶融容器から開口部を通して移動させることができるように構成され、
溶融容器は、開口部を通して押し出された内容物が押出機ユニットの供給開口部を通して押出機ユニットに入るように、押出機ユニットと結合される。
PLGA Resomer(登録商標)Mn 2300(98.42g)およびPLGA Resomer(登録商標)Mn 800(37.49g)を、90℃の温度で混合および溶融ビーカーに直接量り入れた。約10分後、高分子は十分に液体になり、ニカルジピンベースの一部(15.28g)が溶融物に組み込まれた。ニカルジピンベースが溶解し、撹拌により取り込まれた後、予備分散体をビーカー内で超音波装置を用いて100℃の温度で処理した。20kHzで5分間超音波処理した後、蓋を閉じ、溶融状態の予備分散体をパンチで2軸スクリュー押出機(タイプ:Mini CTW)に移した。蓋の温度を70℃に下げながら、押出しを68℃で実行した。
PLGA Resomer(登録商標)Mn 2300(37.61g)の一部をニカルジピンベース(15.19g)と混合した。PLGA Resomer(登録商標)Mn 2300の第2の部分を計量した(58.54g)。PLGA Resomer(登録商標)Mn 2300とニカルジピンベースの混合物、およびPLGAResomer(登録商標)Mn 2300の第2の部分は、表2に示すように低温粉砕された。つまり、PLGA Resomer(登録商標)Mn 2300の一部が個別に粉砕され、PLGA Resomer(登録商標)Mn 2300の第2の部分はニカルジピンベースとともに粉砕された。
