Abstract
化合物式(I)(式中、R1、R2、R3、およびR4は互いに、同一もしくは異なっており、各々、オキソ基、水酸基、メルカプト基、水素原子、ハロゲン原子、アルコキシ基、もしくはアリールオキシ基を表し、点線は、炭素原子のそれぞれの対のうちの1対間が、単結合もしくは2重結合でよいことを指し示す)およびこのエステルが、経皮投与により投与され得る。これらは特に、パッチとして適用されると効果的であり、好ましくは、40〜60重量%のアクリル酸メトキシエチル、30〜40重量%のアクリル酸ラウリルもしくはメタクリル酸ラウリル、および10〜25重量%の極性モノマーのコポリマーを含んでいる接着剤を有している。
Description
パルミチン酸イソプロピルやミリスチン酸イソプロピルのような脂肪酸エステル
モノラウリン酸グリセリルやモノオレイン酸グリセリルのようなグリセロールエステル
ラウリン酸ジエタノールアミドのような酸アミド
ポリエチレングリコールジラウリルエーテルのような中性界面活性剤
を包含する。しかしながら、このような材料は当業界においてよく知られ、如何なる汎用吸収促進剤も、使用されてよい。好ましい吸収促進剤は、ミリスチン酸イソプロピルである。明らかに、該吸収促進剤の量は、薬剤の経皮吸収を促進させるに充分でなくてはならない。しかしながら、多過ぎれば、パッチの接着性を減少させてしまう影響を持つことがある。従って、我々は、吸収促進剤の量が、該コポリマー100重量部につき3〜40重量部であることをより良いと考える。
200gの酢酸エチル(溶媒)、0.05gのアゾビスイソブチロニトリル(イニシエーター、開始剤)、および以降の表1に示されるモノマーが、反応容器中に投入され、次いで窒素を吹き込んだ。重合が次いで実施され、15時間、20℃であった。結果的に得られてきたコポリマー溶液が、ナイフコーターを用いて、ポリエチレンテレフタレートフィルム上に、乾燥時の厚さ100μmまでコーティングされ、次いで、温度90℃において15分間乾燥され、接着シートを生産した。
接着パッチ調製
実施例1の接着剤溶液(コポリマー溶液)中に、および、これら比較例において使用された接着剤溶液中に、下に特定される薬剤、ならびに使用される場合、ミリスチン酸イソプロピルおよび/または架橋剤が加えられ、溶解された。この結果得られてくる組成物は、溶解された薬剤を含有しており、ポリ(エチレンテレフタレート)フィルム上に塗布され、乾燥時100μmの厚さを与え、温度90℃において15分間乾燥され、薬剤含有接着シートを生産した。
1.接着剤中でのHADの飽和濃度
実施例4および比較例1〜5に記載の接着パッチが、段々増加していく濃度のHADと混合され、室温において8週間(接着面を上にして)保管された。この時間の終わりにおいて、これらパッチが吟味され、HADがこれらパッチ表面上で結晶化しているかどうか求めた。これら接着剤中でのHADの飽和濃度が、表4に示される。
実施例5および比較例6〜10に記載の接着パッチが、段々増加していく濃度の7β−OH EPIAと混合され、室温において8週間(接着面を上にして)保管された。この時間の終わりにおいて、これらパッチが吟味され、7β−OH EPIAがこれらパッチ表面上で結晶化しているかどうか求めた。これら接着剤中での7β−OH EPIAの飽和濃度が、表5に示される。
使用された材料は、以降のとおりであった。
動 物:Wistarラット(雄、体重240〜250g)
テスト(試験)パッチ:実施例4および5ならびに比較例1〜10
透過マーカーとして、エストラジオールパッチ商品
(Estrana、久光製薬(株))

7β−OH EPIAに関しては10mm直径
受け皿となる溶 液:PEG400:水(1:3)
HPLC条件

移 動 相 水:アセトニトリル(55:45)
流 速 1mL/分
UV検出器 H A Dに関しては240nm

カラム温度 40℃
上の3.中のプロトコールが、ヒトの皮膚上でHADを用いて繰り返され、実施例4の組成物(表2)を、5%w/w乳酸を促進剤として一緒に、使用した。浸透流束1.1μg/cm2/時間が、ヒトの皮膚中で達成された。
