中に溶解させ、その後に生物/粘膜付着促進剤を溶液に添加し、溶媒を蒸発させ、そして残渣を粒状化させることによる。当業者は他の方法も考えられる。適用される方法に関係なく、生物/粘膜付着促進剤を含有する担体剤の適する粒子寸法部分は最終段階において、例えば粒状混合物を適当なメッシュ寸法のスクリーンまたはふるい、例えば35〜170の米国メッシュ寸法を通すことにより製造される。
実施例1.生物/粘膜付着促進性を有する迅速崩壊性錠剤の製造
1000個の錠剤のバッチを下記の組成物から製造した:81.5gのマンニトールおよび2.0gのAc−Di−SoTM(崩壊剤および生物/粘膜付着促進剤)を約170mlの無水エタノールと混合した。乾燥した混合物を1mmメッシュ幅の金属ふるいの中に強制的に通し、そして約250〜450ミクロンの粒子寸法を有する生じた部分を500mgの微粉状にされたフェンタニルおよび1.0gの微細に粉砕されたラウリル硫酸ナトリウム(界面活性剤)と50時間の期間にわたり混合した。生じた混合物を5.0gのアビセル(Avicel)TMPh101および10.0gのアルギン酸ナトリウム(生物/粘膜付着促進剤および崩壊剤)と60分間の期間にわたり混合した。生じた混合物を200MPaの圧縮圧力で圧縮して錠剤にすると、各錠剤は100mgの重量を有しそして0.5mg
のフェンタニルを含有していた。
実施例2.生物/粘膜付着促進性を有する迅速崩壊性錠剤の製造
1000個の錠剤のバッチを下記の組成物から製造した:91.0gのマンニトール(250〜450μmの粒子寸法の顆粒品質)および1.0gのラウリル硫酸ナトリウムおよび500mgの微粉状にされたフェンタニルをV−ミキサー中で24時間の期間にわたり混合した。その後、5.0gのアビセルPH101および2.0gのAc−Di−SoTM(ここでは両者とも崩壊剤および生物/粘膜付着促進剤として使用された)をさらに2時間にわたり混合した。最後に、0.5gのステアリン酸マグネシウムを2分間にわたり混合した。生じた錠剤物体を130MPaの圧縮圧力で圧縮して錠剤にすると、各錠剤は0.5mgのフェンタニルを含有していた。
実施例3.舌下投与における吸収の評価
癌による突破性疼痛に罹っている一人の患者に400μgのフェンタニルを実施例1に記載された通りにして調合された舌下錠剤として投与した。フェンタニルの血漿濃度を投与後240分間に時間にわたり監視し、そして結果が添付図面に示されている。フェンタニルの吸収は迅速であり、最大値が5分後にすでに得られたことがわかるであろう。これは、本発明に従う舌下調合物がこの投与経路における溶解のために非常に少量の液体だけが利用できるにもかかわらず活性剤の迅速な吸収を与えることを示す。
実施例4.生物/粘膜付着性の評価
本発明に従う調合物の生物/粘膜付着性のインビトロ(in vitro)評価のために、完成した投与量形態に対する生物/粘膜付着性の評価を直接的に行う方法(Sara, G.E. et al., Proc. Int. Symp. Contr. Release Bioact. Mat. 16:420, 1989)を使用した。評価はウサギの腸膜から活性物質を除去するために必要な水流の測定に基づく。ウサギの粘膜片を37℃に設定された適当な温度調節室の中に水平に置いた。組織を最初に予め決められた量の水で蠕動ポンプにより洗浄した。実施例1に従う予備圧縮された組成物(5〜15mg)を次に組織の上に置きそしてそこに2分間とどめて確実に適切に溶解させた。この後、10分間にわたり蠕動ポンプにより供給される水による溶離が行われた。洗い流されたフェンタニルを集め、そして除去されたフェンタニルの割合を決定するためにその量を放射免疫検定法(RIA)により測定した。溶離流速を高めてその後の試験を行った。結果は表1に示されており、高い流速における除去割合は、
A 本発明に従う生物/粘膜付着性混合物(実施例1)、
B 本発明に従う生物/粘膜付着性混合物(実施例2)、
C 生物/粘膜付着促進剤を含有しない迅速溶解のための従来の混合物に関して挙げられている。

以上の記述において、本発明を種々の実施例および好ましい態様を参照しながら記載してきた。しかしながら、当業者には、本発明の範囲はこれらの実施例および態様に限定されないこと並びに本発明の概念から逸脱しないさらなる改変および変更が可能であることは明らかである。発明の範囲はそれ故添付された請求の範囲によってのみ限定される。
