眼時に長時間振とうしなければならない。"Prior Art and Problems to be Solved by the Invention" When formulating a drug with low solubility in water as an eye drop, it is conceivable to formulate an aqueous eye drop in which the drug is suspended. If such aqueous suspension eye drops are left for a long time, the drug will settle, so the container must be shaken and redispersed before use. However, if the precipitated drug causes secondary aggregation such as caking, it cannot be easily redispersed, and the drug must be shaken for a long time when instilled into the eye.
再分散性を良くする方法の一つとして薬物の粒子サイズ
を大きくすることが考えられるが、点眼剤の場合大きな
粒子は眼に対する異物感が生じるという欠点がある。One possible method for improving redispersibility is to increase the particle size of the drug, but in the case of eye drops, large particles have the disadvantage of causing a foreign body sensation to the eyes.
このため、分散性にすぐれた水性懸濁点眼剤を検討する
必要があった。For this reason, it was necessary to consider an aqueous suspension eye drop with excellent dispersibility.
「課題を解決するための手段」
本発明者らは分散性のすぐれた水性M濁点成剤を鋭意検

の、眼に対する異物感が生じる欠点がある。DISCLOSURE OF THE INVENTION Aqueous suspension eye drops are used when formulating drugs with low solubility in water. Such surface suspension type eye drops must be redispersed before use, but drugs that tend to cause secondary aggregation must be left unused for a long time. Although increasing the particle size of the drug improves redispersibility, it has the drawback of causing a foreign body sensation to the eyes.
そこで、本発明者らはこの課題について鋭意検討した結

く、安全性にも問題ないことが確認された。The effects of the present invention will be described in detail in the "Redispersibility Test" section, but the redispersibility of the formulation of the present invention is much better than that of formulations that do not contain water-soluble aluminum salts, and it can be easily redispersed during use. This shows that it can be dispersed. Furthermore, as described in the section "Irritation Test", it was confirmed that the preparation of the present invention did not cause any irritation to the eyes and had no safety problems.

結果を下記に示す。Irritation test As an indicator for examining the eye irritation potential of eye drops, measurement of the number of blinks in rabbits and the Draize test are usually performed. A comparative study was conducted using the aqueous suspension eye drops of Formulation A of Example 1 as an example of the formulation of the present invention, and using physiological saline as a control. The results are shown below.
ウサギに1滴点眼した後の1分間の瞬目回数は両者に差
がなく、刺激は認められなかった。There was no difference in the number of blinks per minute after one drop was instilled into the eyes of rabbits, and no irritation was observed.
