試験方法
油類として、オリーブ油、綿実油、ピーナッツ油、ナタネ油、大豆油、キリ油およびミグリオール812を用いた。ラタノプロスト(イソプロピル-(Z)-7-[(1R, 2R, 3R, 5S)-3,5-ジヒドロキシ-2-[(3R)-3-ヒドロキシ-5-フェニルペンチル]シクロペンチル]-5-ヘプタノエート)5mgを秤取し、それに各油を1000mgずつ秤量して加えた。ラタノプロストが溶解するようにマグネチックスターラーを用いて30分間攪拌し、ラタノプロスト油溶液(5mg/g)を約1000mg調製した。溶解を目視で観察した後、ラタノプロスト油溶液をサンプリングし、HPLC法にてラタノプロスト含量を測定した(0日目)。これらのラタノプロスト油溶液をガラスサンプル瓶に500μLずつ分注し、60℃または80℃で7日間保存した。7日目にサンプリングを行い、ラタノプロスト含量を測定し、0日目の測定値との比から残存率を算出した。各サンプリングは、ラタノプロスト油溶液の一定量を量り、テトラヒドロフランおよび下記移動相Aで希釈して行い、HPLCの測定に供した。
HPLC分析条件:ウォーターズエクステラ RP18,5μm,φ4.6 x 150mmカラムを使用した。移動相Aは アセトニトリル:10mM 1−オクタンスルホン酸ナトリウム塩水溶液(pH3.5)=35:65を、移動相Bは アセトニトリル:10mM 1−オクタンスルホン酸ナトリウム塩水溶液(pH3.5)=10:90であった。注入体積は50μLとし、検出器は紫外吸光光度計(測定波長:210 nm)を用いた。カラム温度は25℃付近の一定温度とした。分析は移動相Aを30min流して行い、その後カラム洗浄のために移動相Bを5min、平衡化のために移動相Aを7min流した。移動相の流速は1.5mL/minであった。
試験方法
ラタノプロスト0.01g、ミグリオール812 2.0g、ゴーセノールEG05(商品名、ポリビニルアルコール部分けん化物、日本合成化学工業)4.0g、濃グリセリン(グリセリン含量98重量%以上)5.2g、精製水 適量をもちいて、全量を100mLにした。すなわち、まず一部の精製水を約70℃に加温し、ゴーセノールと濃グリセリンを加えて溶かして水相を得た。別にラタノプロストをミグリオール812に加えて溶かしたものを油相とした。次に水相をホモミキサー(ROBO MICS、東京特殊機化工業)で撹拌しながら徐々に油相を加えて粗乳化(8000rpm, 15min)し、粗乳化物に滅菌精製水を加えて規定量とした。この粗乳化物をマイクロフルイダイザー(M-110EH、マイクロフルイディクスコーポレーション)を用いて微粒子化(1500 kgf/cm2、10 pass)し、0.01%ラタノプロスト乳剤(原液)を得た。

処方2 0.2%酢酸ナトリウム酸緩衝液(pH5)
処方3 0.2%酢酸ナトリウム酸緩衝液(pH6)
処方4 0.2%リン酸緩衝(pH6)
処方5 0.2%リン酸緩衝(pH7)
処方6 0.2%ホウ酸緩衝液(pH7)
各処方を2mL褐色硝子アンプルに2mLずつ充填し、遮光下、4℃または60℃で4週間保存した。保存サンプルは1週ごとにサンプリングを行い、ラタノプロスト含量を試験例1と同様の条件のHPLC法にて測定した。各サンプルは希釈せずに、そのまま測定に供した。比較対照処方として、キサラタン点眼液(商品名、0.005%ラタノプロスト含有、pH6.5〜6.9、ファルマシア製、Lot No.PT480)を同様の保存条件で保存し、ラタノプロスト含量を測定した。
