Abstract
Description
すなわち、ケトプロフェンの溶解のために使用する特定の溶解剤には、一般に親油性の溶媒が多く、水性貼付剤の製造時において、これらの溶媒を添加する際、注意して行わないと水溶性高分子化合物の不溶化、或いは親油性溶媒の分離等、貼付剤の物性に対して好ましくない影響が出る可能性があった。
しかしながら、本特許文献に記載の貼付剤であっても、水性貼付剤の基剤としてグリセリンは必須成分であるため、長期安定性を考えた場合、エステル化反応による保存安定性の低下が懸念される。また、一般的に貼付剤中に薬物が分散状態で存在すると保存安定性が高くなる反面、経皮吸収性を低くする一因となっており、保存安定性と経皮吸収性が共に良好な水性貼付剤が望まれている。
そのためケトプロフェンを配合した油性貼付剤は経皮吸収性が高く、かつ、これらの油性貼付剤は多価アルコール類を配合しなくともその物性が維持できるため、ケトプロフェンの高い安定性を得ることができる。
以下、本発明について、さらに詳細に説明する。
膏体中のケトプロフェンの含量が0.1重量%未満であるとケトプロフェンの経皮吸収性が不十分となり、また、5重量%を超えて配合しても、使用後に経皮吸収されずに製剤中に残存する主薬成分が多くなり、好ましくない。
使用されるアミン類としては例えば、モノエタノールアミン、ジエタノールアミン、トリエタノールアミン、ジイソプロパノールアミン、トリイソプロパノールアミン等が挙げられ、特にジイソプロパノールアミンが好ましい。
膏体中のアミンの含量が0.5重量%未満であると製剤中のケトプロフェンの溶解が不十分となり、結果として結晶析出あるいは経皮吸収性の低下等、好ましくない影響が出るおそれがある。
一方10重量%を超えて配合すると、製剤のpHが過度に上昇し、粘着力の低下等、製剤の物性に好ましくない影響が出る。
平均分子量が600より大きいポリエチレングリコールについては、その融点が40℃を越えるため、本発明の水性貼付剤に配合した場合、水溶性高分子等の基剤成分を十分に分散することができず、未溶解の基剤成分が現れてくる可能性があり好ましくない。
膏体中のポリエチレングリコールの含量が5重量%未満であると、製剤中のケトプロフェンの安定性が低下してしまい、また、30重量%を超える場合には、貼付時にダレが生じるなど、製剤の物性に影響が出て好ましいものではない。
そのような基剤成分としては特に限定されるものではないが、例えば、通常使用されるポリアクリル酸ナトリウム、ポリアクリル酸、カルボキシビニルポリマー、カルメロースナトリウム、ヒドロキシプロピルセルロース、ポリビニルアルコール、ゼラチン等の水溶性高分子化合物;グリセリン、プロピレングリコール、1,3-ブチレングリコール等の多価アルコール類;水酸化アルミニウム、硫酸アルミニウムカリウム、アルミニウムグリシネート等の架橋剤;カオリン、酸化チタン等の無機粉末;クエン酸、エデト酸ナトリウム、酒石酸等のpH調整剤;ポリオキシエチレンソルビタンモノオレエート、ソルビタンモノオレエート、ポリオキシエチレンモノオレエート、グリセリン脂肪酸エステル、ポリグリセリン脂肪酸エステル、ポリオキシエチレン脂肪酸エステル、ソルビタン脂肪酸エステル、ポリオキシエチレンソルビタン脂肪酸エステル、ポリオキシエチレンソルビット脂肪酸エステル、ポリオキシエチレン硬化ヒマシ油、ポリオキシエチレンアルキルエーテル等の界面活性剤;メチルパラベン、プロピルパラベン等の防腐剤;及び精製水等が挙げられる。
さらに必要に応じて吸収促進剤、抗酸化剤、着香剤、着色剤等を適宜適量添加することができる。

実施例1で得られた水性貼付剤、および市販品である比較例1のケトプロフェン2重量%含有プラスター剤について、ラット皮膚を用いたin vitroでの皮膚透過試験を行った。
除毛した雄性ラット(ウィスター系、7週齢)の背部摘出皮膚を37℃に保温した縦型の透過試験用拡散セルに固定し、摘出皮膚の角質層側には試験対象である製剤を貼付し、内側(真皮層側)にはレシーバー液としてリン酸緩衝生理食塩水(PBS)を10mL加えた。その後、経時的にレシーバー液を0.2mL採取し、液体クロマトグラフ法によりケトプロフェン透過量を測定し、その値から皮膚透過速度(flux)を計算した。
その結果を図1に示した。
実施例1で得られた水性貼付剤、及び市販品である比較例1のケトプロフェン2重量%含有プラスター剤について、ウサギ皮膚一次刺激性試験を行った。
それぞれの製剤を除毛したウサギ背部に24時間貼付し、剥離後1時間目、24時間目及び48時間目の皮膚症状から刺激指数(P.I.I.)を求めた。
刺激指数(P.I.I.)の評価基準を下記表6に示した。
本発明が提供する水性貼付剤は、従来のケトプロフェン含有貼付剤に比べて高いケトプロフェンの優れた経皮吸収性、安全性、および高い保存安定性を兼ね備えたものであり、その医療上の有用性は多大なものである。
