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1〜15および比較例1〜9の保管された貼付製剤を得た。
塩酸ドネペジルおよび2種の添加剤を配合しないこと以外は、実施例1と同様に処理して、参考例1の保管された貼付製剤(プラセボ製剤)を得た。
2種の添加剤を配合しないこと以外は、実施例1と同様に処理して、参考例2の保管された貼付製剤(コントロール製剤)を得た。
まず、参考例1の貼付製剤(プラセボ製剤)の色彩を、CIE1976(L*a*b*)表色系(エルスター・エースター・ビースター表色系 JIS Z 8729)により表される色彩値(L*s,a*s,b*s)とし、次いで、実施例1〜15および比較例1〜9の貼付製剤、ならびに参考例2の貼付製剤(コントロール製剤)の各々の色彩を、CIE1976(L*a*b*)表色系(エルスター・エースター・ビースター表色系 JIS Z 8729)により表される色彩値(L*1,a*1,b*1)とした。
そして、得られた参考例1の貼付製剤(プラセボ製剤)の色彩値(L*s,a*s,b*s)を基準点として、実施例1〜15および比較例1〜9の貼付製剤ならびに参考例2の貼付製剤(コントロール製剤)の色彩値(L*1,a*1,b*1)との色差(△E*ab1)を、下記式1にしたがって算出した。結果を表2に示す。
△E*ab1=[(L*1-L*s) 2+(a*1-a*s) 2+(b*1-b*s) 2]1/2 ・・・ (式1)
次いで、実施例1〜15および比較例1〜9の貼付製剤、および参考例2の貼付製剤(コントロール製剤)を、23℃の恒温条件で8〜11ヶ月保存した後、長期保存後の実施例1〜15および比較例1〜9の貼付製剤、および参考例2の貼付製剤(コントロール製剤)の色彩値(L*t,a*t,b*t)を、上記と同様に測定した。
そして、上述した各製剤の長期保存前の色彩値(L*1,a*1,b*1)を基準点として、実施例1〜15および比較例1〜9の貼付製剤ならびに参考例2の貼付製剤(コントロール製剤)の長期保存後の色彩値(L*t,a*t,b*t)との色差(△E*ab2)を、下記式2にしたがって算出した。結果を表2に示す。
△E*ab2=[(L*t-L*1) 2+(a*t-a*1) 2+(b*t-b*1) 2]1/2 ・・・ (式2)
安定化剤を表3に示す2種の安定化剤(各々0.5重量部)に変更したこと以外は、実施例1と同様に操作して、実施例16〜30の保管された貼付製剤を得た。
得られた実施例16〜30の保管された貼付製剤の色彩値(L*1,a*1,b*1)および長期保存後の色彩値(L*t,a*t,b*t)を上記と同様に測定し、上述の式1および式2にしたがって、各々の△E*ab1および△E*ab2を算出した。結果を、表3に示す。
また、実施例16、実施例17、実施例19、実施例20、実施例22、実施例24、実施例26および実施例27においては、長期保存前後の色差△E*ab2が、併用した安定化剤の各々単独の経時的な変色抑制効果の相加平均(実施例1、実施例4、実施例5、実施例8、実施例11および実施例12の色差△E*ab2に基づいて計算される値であり、それぞれ、1.1、1.3、0.8、34.5、0.7、0.6、0.3および0.3となる。)を下回る値となった。このことから、これらの実施例にて用いている安定化剤の組み合わせによれば、ドネペジル含有貼付製剤の経時的な変色の抑制効果が相乗的に発揮されることが判明した。
