実施例23で調製した本発明の医薬組成物(ミラベグロンを50mg相当量含有する)を水50mLに分散させ、ビーグル犬6例に絶食条件および食後30分後にゾンデにより経口投与し、血漿中に含まれる薬物濃度を測定した。食餌は肉試料50gを用いた。
本発明の医薬組成物(実施例23)は、絶食下に比べ、飽食下でのCmaxの低下率が-9%、AUCの低下率が15%となり、比較例1の結果(表4)と比較して食物摂取の有無による薬物動態の変動を低減する傾向がみられた。
実施例20および23で調製した本発明の医薬組成物を水に分散させた懸濁液をガラス瓶に充填し、密栓後、冷所(5℃)にてそれぞれ2週間保存した。保存後、懸濁液(ミラベグロンを25mg相当量含有する)の溶出試験を日本薬局方溶出試験法第二法(パドル法)に従い行った。試験液はUSPリン酸緩衝液(pH6.8)900mLを用いた。パドル回転数は200rpmで行った。
