また、より好ましい態様では、特定の類縁物質の生成量の減少だけでなく、類縁物質の総生成量も低減することができるので、安全かつ安定性が極めて高いドネペジル含有貼付製剤を達成できる。
また、より好ましい態様では、2種以上の安定化剤を組み合わせることで、それらの安定化剤単独により得られる、類縁物質の生成量の相加平均値と比較して、類縁物質の生成量がより一層抑制される(すなわち相乗的に抑制される)。従って、安定化剤を多量に使用する必要性がなく、安全かつ安定性の高いドネペジル含有貼付製剤を効率良く得ることができる。
本発明の貼付製剤は、支持体と、支持体の少なくとも片面に形成された粘着剤層とを含み、該粘着剤層が、ドネペジルと、粘着剤と、安定化剤とを少なくとも含有する。
不活性ガス雰囲気下、アクリル酸2−エチルへキシル75部、N−ビニル−2−ピロリドン22部、アクリル酸3部およびアゾビスイソブチロニトリル0.2部を酢酸エチル中60℃にて溶液重合させて粘着剤Aの酢酸エチル溶液(粘着剤固形分:28%)を得た。
次に、下記表2に示す安定化剤を含み、下記表1の配合組成を混合し、酢酸エチルで粘度調整して塗工液を得た。これをポリエチレンテレフタレート(PET)剥離ライナー上に乾燥後厚60μmとなるよう塗布し、乾燥し、これにPET支持体を貼り合せて貼付製剤を得た後、70℃、48時間保管して実施例1〜19および比較例1〜6の保管された貼付製剤を得た。
実施例および比較例の貼付製剤をメタノール抽出し、この抽出液を次の条件でHPLC分析した。
(HPLC条件)
HPLC−カラム:Inertsil(登録商標)ODS−2(4.6mmI.D.×15cm、5μm)GLサイエンス社製
カラム温度:35℃
移動相:1−デカンスルホン酸ナトリウム水溶液/アセトニトリル/70%過塩素酸=650/350/1(体積比)
1−デカンスルホン酸ナトリウム濃度は移動相全体に対して10mM
流速:1.4mL/min
検出:UV(271nm)
リテンションタイム:ドネペジル 11.0分、類縁物質1 12.8分、類縁物質2 3.9分
実施例1において、1.0部のL(+)-アスコルビン酸(以下、「アスコルビン酸」という)を、0.5部のアスコルビン酸および0.5部のD(-)-イソアスコルビン酸(以下「イソアスコルビン酸」という)に置き換えたほかは、実施例1と同様にして実施例20の保管された貼付製剤を得た。また、同様に、実施例20において、0.5部のアスコルビン酸および0.5部のイソアスコルビン酸を、表3に記載の安定化剤の組み合わせ(それぞれ0.5部ずつ)に置き換えたほかは実施例20と同様にして実施例21〜24の保管された貼付製剤を得た。これらの貼付製剤について上記と同様に分析した。
実施例1において、1.0部のアスコルビン酸を、0.99部のアスコルビン酸および0.01部のメタ重亜硫酸ナトリウムに置き換えたほかは、実施例1と同様にして実施例Aの保管された貼付製剤を得た。同様に、表4に記載のとおりこれらの安定化剤の配合量を変えたほかは実施例Aと同様にして、実施例B〜Iの保管された貼付製剤を得た。
◎ 非常に良好な粘着物性を有する
○ 良好な粘着物性を有する
△ 若干粘着物性が低下しているが許容範囲である
その結果を表4に示した。
表4の結果から明らかなように、実施例A〜Dでは、類縁物質2の生成は抑制された。しかし、アスコルビン酸を、粘着剤層総重量基準で、0.01重量%まで減少させると、類縁物質2の生成が増加した。表4を参照すると、アスコルビン酸が粘着剤層総重量基準で0.02重量%含有させた場合、類縁物質2の生成は抑制された。一方、表4より明らかなように、アスコルビン酸を粘着剤層総重量基準で1重量%近く含有させると、粘着物性がやや低下したが、0.5重量%含有させた場合には改善され、0.1重量%含有させた場合にはより改善された。また、実施例Eのほうが実施例17よりも安定化効果が高く、実施例Cは実施例Bよりも粘着物性が良好であり、実施例Bは実施例Aよりも粘着物性が良好であったことから、アスコルビン酸:メタ重亜硫酸ナトリウムの重量比は100:1〜1:100が好ましく、10:1〜1:100がより好ましく、1:1〜1:100が最も好ましいことが示された。さらに、実施例Fは参考例と比較して各成分とも顕著に生成量が抑制されたことから、良好な相乗的な安定化効果を示した。
また、表4の結果から、粘着剤層の総重量(すなわち、粘着剤層形成に使用する調合物の固形分総重量)に対し、アスコルビン酸が0.01〜9.99重量%およびメタ重亜硫酸塩が0.01〜9.99重量%の配合割合、より好ましくは、アスコルビン酸が0.02〜9.99重量%およびメタ重亜硫酸塩が0.01〜9.91重量%において、安定化効果が明確に確認された。さらには、表4の結果から、安定化効果の観点からは、アスコルビン酸:メタ重亜硫酸ナトリウムの重量比は、1:100〜100:1が好ましく、1:10〜100:1がより好ましく、1:25〜100:1が最も好ましいことが示された。
