なお、以下の試験例において、リパスジル1塩酸塩2水和物は、例えば国際公開第2006/057397号パンフレット記載の方法により製造することが出来る。また、ブリモニジン酒石酸塩は、例えば米国特許第3890319号明細書記載の方法により製造することが出来る。
表1に示す処方の水性組成物を常法により調製し、-5℃で保存しつつ、定期的に結晶析出の有無を目視により評価し、いずれの水性組成物に先に結晶析出が認められるかを確認した。先に結晶析出が認められなかったものを○、先に結晶析出が認められたものを×として、結果を表1に示した。
以上の試験結果から、リパスジルに代表される一般式(1)で表される化合物若しくはその塩又はそれらの溶媒和物を含有する水性組成物にさらにブリモニジン又はその塩を含有せしめると、低温で保存した場合、相対的に結晶が析出し難く、保存安定性に優れることが明らかとなった。
