Abstract
【解決手段】 本発明の貼付剤は、その膏体層中に、炭素数が8〜22の脂肪族炭化水素基を有する脂肪酸を所定量含有していることから、膏体層中の遊離塩基性薬物の保存安定性を損ねることなく、遊離塩基性薬物の溶解性及び拡散性を向上させて経皮吸収性を高めており、膏体層中に充分な量の遊離塩基性薬物が拡散された状態で含有されているため、持続的な遊離塩基性薬物の経皮投与が可能である。

Description
ドデシルメタクリレート13重量部、2−エチルヘキシルメタクリレート78重量部、2−エチルヘキシルアクリレート9重量部、及び、酢酸エチル50重量部からなる反応液を40リットルの重合機へ投入し、重合機内を80℃の窒素雰囲気とした。そして、上記反応液にベンゾイルパーオキサイド0.5重量部をシクロヘキサン50重量部に溶解させてなる重合開始剤溶液を24時間かけて加えながら重合させ、重合後更に酢酸エチルを加えて、アクリル系粘着剤A含有量35重量%のアクリル系粘着剤A溶液を得た。
2−エチルヘキシルアクリレート100重量部、エチルアクリレート80重量部、ビニルピロリドン20重量部、及び、酢酸エチル200重量部からなる反応液をセパラブルフラスコに投入した後、このセパラブルフラスコ内を80℃の窒素雰囲気とした。そして、この反応液にベンゾイルパーオキサイド1重量部を酢酸エチル100重量部に溶解させてなる重合開始剤溶液を27時間かけて加えながら重合させ、重合後更に酢酸エチルを加えて、アクリル系粘着剤B含有量32重量%のアクリル系粘着剤B溶液を得た。
膏体層におけるアゼラスチン、アゼラスチン塩酸塩、脂肪酸、脂肪酸エステル及びアクリル系粘着剤A,Bの重量組成が表1、2に示した割合となるように、アゼラスチン、アゼラスチン塩酸塩、脂肪酸、脂肪酸エステル及びアクリル系粘着剤A,B溶液を配合し、固形分の濃度が22重量%になるように酢酸エチルを加えた後、均一になるまで混合して、膏体層溶液を調製した。表1、2の脂肪酸の欄において、化合物の右横の括弧内には、脂肪族炭化水素基の炭素数を記載した。
貼付剤の製造直後において、目視及び顕微鏡で膏体層表面を観察し、結晶の析出状態を観察した。更に、貼付剤から一辺が10cmの試験片を切り出し、この試験片を遮光した包材に密封して室温にて6カ月間に亘って保存した。6カ月後に再び、膏体層表面を観察して結晶の析出状態を目視及び顕微鏡で観察した。膏体層の表面に結晶が析出していなかった場合を「○」、結晶が析出していた場合を「×」とした。
実施例1、5及び比較例1、4〜6で得られた製造直後の貼付剤から直径2cmの平面円形状の試験片(貼付面積:3.14cm2)を切り出す一方、37℃に保持されたFranzの拡散セルに、ヘアレスマウス(雄、8〜10週齢)の背部摘出皮膚を固定し、この皮膚の上端部に試験片をその膏体層によって貼付した。なお、pH7.2に調整した生理食塩水をリセプター液とし、このリセプター液中に皮膚の下端部を浸漬した。
実施例6〜8及び比較例7、8について、皮膚に対する薬物吸収性を評価する目的で、ラット貼付試験におけるアゼラスチン移行量を以下の方法で評価した。
アゼラスチン移行量(μg/cm2/24h)=(W1−W2)/3 ・・・式(1)
