Description
先ず、酒石酸トルテロジン(0.9g)及び水酸化ナトリウム(0.15g:酒石酸トルテロジンに対し2倍モル当量)、トルテロジンアセテート(0.026g)をアクリル粘着剤(4.97g:「DURO-TAK 4287」、ヘンケル社製)の酢酸エチル溶液(固形分濃度40質量%)に加え粘着剤層組成物を得た。
トルテロジンアセテートを加えなかったこと以外は実施例1と同様にして貼付剤を得た。
トルテロジンアセテートを加えなかったこと以外は実施例1と同様にして得られた貼付剤を温度60℃で2週間放置して目的の貼付剤を得た。
アクリル粘着剤として酢酸ビニルを構成モノマーとして含有しないアクリル粘着剤(5.07g:「MAS 811」、積水化学工業(株)製)の酢酸エチル溶液を用いたこと以外は実施例2と同様にして貼付剤を得た。
酒石酸トルテロジンを0.75gとし、水酸化ナトリウムを0.13gとし、アクリル粘着剤の酢酸エチル溶液の代わりにスチレン-イソプレン-スチレンブロック共重合体0.69g及びポリイソブチレン0.29gのトルエン溶液を用い、粘着付与樹脂1.79g(「アルコンP100」)及び流動パラフィン1.34gを添加したこと以外は実施例2と同様にして貼付剤を得た。
実施例1及び比較例1で得られた貼付剤について、各貼付剤を得てから48時間以内に剥離試験を行った。剥離試験は、JIS Z 0237「粘着テープ・粘着シート試験方法」の方法1に準じて行い、引張試験器(「テンシロンRTM-100」、(株)オリエンテック製)を用いて各貼付剤の粘着力を測定した。得られた結果を表1に示す。
実施例2及び比較例1~3で得られた貼付剤から試料として6.25cm2を採取し、ここにメタノール20gを加えて室温にて5時間攪拌して薬物の抽出液を得た。得られた抽出液について、高速液体クロマトグラフィー装置((株)島津製作所製、カラム:ODSカラム、溶媒:リン酸緩衝液(0.2質量/体積%)/メタノール=50/50(体積比)、検出波長:UV210nm)を用いてトルテロジンアセテートを検出し、各試料におけるトルテロジンアセテートの生成を評価した。なお、比較例1で得られた貼付剤については、貼付剤を得てから48時間以内に本測定を行った。その結果、実施例2で得られた貼付剤においてはトルテロジンアセテートが検出され、粘着剤層にトルテロジアセテートが生成することが認められた。一方、比較例1~3で得られた貼付剤においては、トルテロジンアセテートが検出されず、トルテロジンアセテートの生成は認められなかった。
