本発明の水性組成物は、ケトチフェン及びその塩からなる群より選択される少なくとも1種(以下、単に(A)成分と表記することもある)を含有する。
前述するように、水性組成物中で上記(B)成分との共存によって生じる上記(A)成分の熱に対する不安定化を、上記(C)成分を配合し且つ該水性組成物のpHを6.5以下にすることによって抑制することができる。
また、前述するように、上記(C)成分を含み、且つpHが6.5以下の水性組成物は、上記(B)成分との共存によって生じる上記(A)成分の熱に対する不安定化を抑制することができる。
下記の表1に示す試験液(試験液1−4)を調製して、フマル酸ケトチフェンの熱に対する安定性の評価を行った。フマル酸ケトチフェンは不安定になると製剤を黄変させることが知られており、本試験例では、試験液の黄変の程度を調べることにより、フマル酸ケトチフェンの熱安定性の評価を行った。具体的な実験手法及び結果を以下に示す。
下記の表2に従い、各試験液を調整して、フマル酸ケトチフェンの熱に対する安定性の評価を行った。具体的な実験手法及び結果を以下に示す。
下記表3に記載の各試験液を、ホウ砂の配合量を適宜調整することにより、それぞれ2種類のpH(具体的には、pH6.2及び7.0)になるように調製した。次いで、各試験液について、ガラス製のヘッドスペースバイアルへの充填量を8mlから5mlに変更した以外は上記試験例2と同様の方法で、フマル酸ケトチフェンの熱に対する安定性の評価を行った。
下記表4に記載の各試験液を、ホウ砂の配合量を適宜調整することにより所定のpHになるようにして調製し、ガラス製のヘッドスペースバイアルを用いて上記試験例2と同様の方法で、各試験液についてフマル酸ケトチフェンの熱に対する安定性の評価を行った。
以上の結果より、ジブチルヒドロキシトルエンを配合したうえで、水性組成物のpHを6.5以下とすることにより、プラノプロフェンによってもたらされるフマル酸ケトチフェンの熱に対する不安定化を著しく抑制でき、高温条件下でも黄変を生じさせない、製剤的に優れた水性組成物が得られることが明らかとなった。また、より格段顕著に高いフマル酸ケトチフェンの熱安定性改善効果を得るためには、更に多価アルコールとしてグリセリンを組み合わせることが有益であることも認められた。
表5に記載の処方で、点眼剤(実施例1−12)が調製される。
