Description
(1)ロテプレドノールエタボネート、非イオン性界面活性剤および、ソルビン酸またはその塩ならびにパラオキシ安息香酸エステルからなる群より選択される少なくとも1種を含有してなる水性懸濁液剤、
(2)点眼剤である(1)記載の水性懸濁液剤、
(3)点鼻剤である(1)記載の水性懸濁液剤、
(4)点耳剤である(1)記載の水性懸濁液剤、
(5)ロテプレドノールエタボネートと非イオン性界面活性剤とを含有する水性懸濁液剤に、ソルビン酸またはその塩ならびにパラオキシ安息香酸エステルからなる群より選択される少なくとも1種を配合することを特徴とする、ロテプレドノールエタボネートの再分散性を向上させる方法、
に関する物である。
本発明の水性懸濁液剤中のLE濃度は、炎症の治療上効果のある濃度であればよく、下限濃度が通常約0.01w/v%、好ましくは約0.05w/v%、さらに好ましくは約0.1w/v%で、上限濃度が通常約2.0w/v%、好ましくは約1.5w/v%、さらに好ましくは約1.0w/v%である。
(試験方法)
下記表1に示すLE含有水性懸濁液を常法に従って調製し、5mLずつポリプロピレン(PP)容器に充填した(n=4)。正立状態で4℃、1週間保存し、LE粒子を沈降させた。その後、容器を反転し、40℃、75%RH条件下で1週間保存し、LEを容器に付着させた。4℃、1週間および40℃、1週間保存した後、容器を20回振盪し、容器への固着物および沈降物剥離後の凝集物(ブロック)の有無を目視で観察した。また、正立状態で4℃、2週間保存したLE含有水性懸濁液について、沈降物が容器から剥離するのに要した振盪回数を測定した。
試験結果を下記表2に示した。
この結果は、LEを含有する水性懸濁液にソルビン酸塩を配合することにより、沈降したLE粒子の容器への固着および剥離後のブロック形成が抑制され、かつ沈降したLE粒子が容易に容器から剥離し、再分散性が向上したことを示す。
(試験方法)
下記表3に示すLE含有水性懸濁液を常法に従って調製し、5mLずつポリプロピレン(PP)容器に充填した(n=8)。正立状態で4℃、1週間保存し、LE粒子を沈降させた。その後、容器を反転し、40℃、75%RH条件下で1週間保存し、LEを容器底面に付着させた。4℃、1週間および40℃、1週間保存した後、容器を振盪し、沈降物が容器から剥離するのに要した振盪回数を測定した。
試験結果を下記表4に示した。
この結果は、LEを含有する水性懸濁液にソルビン酸塩またはパラオキシ安息香酸エステルを配合することにより、沈降したLE粒子が容易に容器から剥離し、再分散性が向上したことを示す。
