Abstract
【解決手段】イトラコナゾールにシクロデキストリンを混合することにより非晶質化し、さらにこの混合物にキサンタンガムを添加することにより、従来のイトラコナゾール含有の内服剤と比較して付着性が大幅に増加し、口腔滞留性を著しく向上された高付着性ゾル状医薬組成物。
【選択図】なし
Description
注2)表中の※1は、固形化したために測定不可能であった。
注3)表中の※2市販剤に関する補足情報として、使用している添加物を○、不使用の添加物を−で示す。なお、市販剤はこれ以外に、プロピレングリコール、水酸化ナトリウム、サッカリンナトリウム水和物、カラメル、香料を含む。
実施例、比較例及び市販剤について、粘度を測定した。粘度測定は、音叉型振動式粘度計(エー・アンド・デイ製SV−10)を使用し、検体量35mL、温度20℃±2℃で測定した。結果は表1に示す。実施例1〜8のゾル状医薬組成物は、比較例及び市販剤と比較して高い粘度を示した。
実施例、比較例及び市販剤について、付着性を測定した。具体的には島津製作所製小形卓上試験機EZ−SHORTを使用し、厚労省「えん下困難者用食品の規格基準」に準じ、付着性を測定した。結果は表1に示す。実施例1〜8のゾル状医薬組成物は、比較例及び市販剤と比較して高い付着性を示した。
実施例、市販剤について、口内残存率を測定した。具体的には検体20gを口に含み、口腔内全体に広げた後、吐き出して回収し、その質量を測定することで口内残存率を算出した(n=5)。その結果を表1に示す。実施例1〜8のゾル状医薬組成物は、比較例及び市販剤と比較して高い口内残存率を示した。
実施例、市販剤について、溶出試験を実施した。具体的には、日本薬局方溶出試験に準じ、パドル法、試験液として溶出試験第1液900mLを使用し、検体20gとした。30分後の試験液を採取し、HPLCで主薬の溶出率を測定した。その結果を表1に示す。実施例1〜8のゾル状医薬組成物は、いずれも市販剤と比較して溶出率が同程度であった。
服用感を官能的に評価した。検体は、実施例1,5のゾル状医薬組成物ならびに市販剤とした。実施例1,5の検体又は市販剤の検体1回約20gを口に含み、1分間保持した後吐き出させ、各製剤の服用感を、表8に示す評価項目及び4段階の採点基準にしたがって採点し評価した。
