以與本發明製劑1之製備方法相同方法,製備表1所示之本發明製劑及比較製劑。
以LC-MS/MS法測定將上述(1-1)中所調製之各製劑單次點眼於JW品系雄性白色兔子時,點眼後1及2小時之眼房液中之本化合物的濃度(1時間點4眼)。
1)以微量分注器MICROMAN將各製劑50μL點眼於角膜上。點眼後保定約30秒鐘。
2)於指定時間未麻醉下,在兔子置入於固定器之狀態下自耳静脈注入戊巴比妥製劑(商品名:Somnopentil注射液)約4mL使其死亡。
3)使眼球突出並以生理食鹽液清洗後採集眼房液。
4)所採集之眼房液,每1眼使用50μL並進行前處理後,以LC-MS/MS法測定,並將4眼之平均值呈示於結果。

於2.4g甘油中添加純水90mL並予以溶解。溶解後,添加0.15g磷酸二氫鈉、0.1g本化合物並使之溶解。進一步,除了分別添加適量氫氧化鈉,使製劑之pH為6.0左右之外,添加適量純水並使總量為100mL,而作為含有0.1w/v%本化合物之比較製劑4。
檢討將含有0.1w/v%本化合物之本發明製劑9或含有0.1w/v%本化合物之比較製劑4分別單次點眼20μL時之眼壓下降效果。又,使用食蟹彌猴(Cynomolgus monkey)(性別:雄性、一組6至8隻)作為實驗動物。
1)將一滴0.4%奧布卡因鹽酸鹽(oxybuprocainehydrochloride)點眼液(商品名:Benoxil0.4%液)點眼於實驗動物之眼壓測定眼,以進行局部麻醉。
2)於各試驗製劑點眼前立即測定眼壓並作為初期眼壓。
3)將各試驗製劑點眼於實驗動物之單眼(對側眼未處置)。
4)於各試驗製劑點眼後2小時、4小時及6小時,分別將一滴0.4%奧布卡因鹽酸鹽點眼液點眼於眼壓測定眼以局部麻醉後進行眼壓測定。又,眼壓測定各3次,並將其平均值呈示於結果。
