Abstract
Description
WO9302664号には、親油相(中鎖トリグリセリドおよび低HLB値を有する界面活性剤(5:1〜1.5:1の比率))、水性親水相、高HLB値を有する界面活性剤および水溶性治療剤を含む油中水滴型マイクロエマルジョンが開示されている。
該目的は、請求項1の特徴的な態様により達成される。本発明は、使用に関し、請求項14〜20の態様により達成される。
界面活性剤/補-界面活性剤混合物は、ポリオキシエチレングリセロール脂肪酸エステルとポロキサマーを2:3の質量比で含む場合、特に優れた結果を達成することができた。
本発明のさらに有利な具体例によれば、親水相の場合、1:10〜10:1の比率のプロピレングリコールおよび水の混合物を用いることが提供される。特に好ましい混合物比は、2:1である。
本発明による医薬製剤は、炎症性皮膚および粘膜疾患の予防のために、アトピー性皮膚炎の治療および予防のために、尋常性乾癬の治療および予防のために特に適当である。
本発明を、以下により詳細に、種々の組成および試験結果を用いて記載する。
3つのコロイド状薬剤キャリアシステムを開発したが、その組成を表1に明示する。
-薬剤を計量すること、
-界面活性剤/補-界面活性剤混合物を添加すること、
-粉砕工程を経ること、
-所望量のIPPを添加すること、
-混合工程を経ること、
-作成された、プロピレングリコールおよび水の混合物を添加すること、
-透明になるまで攪拌すること、なお、超音波で該コロイド状システムを短時間処理してよい。
薬剤キャリアシステムを特に、動的レーザー光散乱光度計を用いて特定した。本方法は、液体媒質中のコロイド粒子のサイズの測定に適している。薬剤を含まない製剤に関して、約20nmの粒子直径を測定することができた。
CsAの測定を、HPLC法(Merck KgaA-Darmstadtにより変更)を用いて行った。テクニカルデータを表2に示す。
多層膜モデルシステムを用いて、前記製剤からの薬剤のインビトロでの放出を、時間の関数として試験した。
ビヒクルからのCsAの十分な放出が達成されること、およびそれゆえ、ヒトの皮膚への透過のための必要条件が満たされることを保証するために、これらの試験を行った。
乳房減少形成手術により得た乳房由来のヒトの皮膚を用いた。断片化した皮膚片を、−3℃にて保存した。解凍した後、表面に付着している液体をコットンパッドで除去し、3.14cm2の規定の表面を切り出した。表面に、1cm2当たり約6mgの放射能活性標識試験製剤を適用し、出来るだけ均一なフィルムを皮膚表面に作成した。次いで、ガーゼ上に並んでいる皮膚片を、32℃の温度に設定したFranz 型拡散セル中に伸ばした。充填状態における試験の開始前に、同じものを、30分の平衡相に供した。拡散層の濃さを減じるために継続的に振とうしたアクセプター媒質を、皮膚またはガーゼの底側面に、直接接せしめた。生理学的条件を擬似するために、等張のNaCl溶液をアクセプター液として用いた。試験は、3倍測定として、3つの異なる手術調製物に関してそれぞれ行った。作動期間完了後、皮膚片を取り出し、ピンを用いてアルミニウムホイルで覆ったスタイロポアボックス上に固定した。
WO94/08603号、WO94/08605号およびWO99/39700号においては、コロイド状システムにおいて潜在的活性成分としてシクロスポリンおよびその誘導体を含む医薬製剤が記載されている。
