Description
1.封入体の粒子状活性成分内容物の粒子サイズの選択:これは、前に述べた「オストワルド−フロインドリッヒの法則」によって、対応するより高い飽和溶解度をもたらす;そして
2.経皮システムの層の熱によって起こる乾燥から生じ、熱によって引き起こされる過飽和に帰着する可能性がある付加的効果。
微粒子の製造:
ゼラチン(2.5g)を水(100mL)に50℃で溶解した。次いで、活性成分結晶(微粉化したテストステロン)(0.5g)をゼラチン溶液に懸濁させた(4枚翼攪拌器、500〜1,000rpm)。次に、その懸濁液をアラビアゴム(2.5%、質量/体積)の水溶液の入ったガラスビーカーに加えた。水(400mL)を添加し、塩酸(1N)を用いてpHを3.0〜4.3に下げ、混合物を4℃に冷却した。マイクロカプセルを2時間析出させた後、上清をデカントして除き、沈降物にエタノール(2×150mL)を添加して粒子を固化した。最後に、マイクロカプセルを濾取し、恒量になるまで通夜乾燥した。
テストステロン(0.5g)を、エチルセルロースのエタノール溶液(濃度27.3%、10.0g)に溶解した。次いで、その溶液をシリコーン接着剤(例えば、Bio Psa 4201)(14.0g)中に懸濁し、均質に撹拌して組成物を作成した。次に、この組成物を手動式ナイフコーターを用いてフラワー重合した(flour polymerized)100μmのPETフィルム上に、50〜100μmの層厚に延展し、80℃で乾燥して、透明な15μmのPETフィルムを積層した。
