参考例1について、試験結果より算出した最高血漿中濃度(Cmax)は128.7μg/mL、0時間から2時間までの血中濃度曲線下面積(AUC0-2)は97.8μg・hr/mL、0時間から24時間までの血中濃度曲線下面積(AUC0-24)は1036.3μg・hr/mLとなった。なお、各パラメーターの算出の際には各血中濃度より投与前の血漿中EPA濃度を減じた補正を行っている。実施例1~8の医薬組成物についても同様の挙動を示す。
実施例および参考例で得られた各軟カプセルについて、充てん、乾燥終了後、カプセルの色、形状および充てん液の性状について目視にて確認する。
色については変色が認められるもの、形状については歪みや凹み等が認められるもの、充てん液の性状については濁りや分離等が認められるものをそれぞれ不良とし、いずれも認められないものを正常とする。
参考例1のカプセルの外観は正常であった。実施例1~8の医薬組成物を充填したカプセルについても同様の挙動を示す。
下記表中「―」の記載は、該当成分を添加せず、または測定せずを示す。
なお、ピタバスタチンカルシウム10mgに代えて、アトルバスタチンカルシウム100mgを用いて、実施例1の方法にて検討したが、アトルバスタチンカルシウムは溶解せず、良好な外観は得られなかった。
実施例2の医薬組成物は、自己乳化性等にも優れている。また、過酷条件保管後の外観にも優れている。ビーグル犬における薬物動態試験においても良好な吸収を示す。

実施例5は、実施例1のポリオキシエチレン(20)ソルビタンオレイン酸エステルの代わりに、トリオレイン酸ポリオキシエチレン(20)ソルビタンを使用し、加えて、その他成分を含めて配合比を変更したものである。ピタバスタチンカルシウムが完全に溶解し、医薬組成物の外観が良好であった。自己乳化性にも優れていた。また、過酷条件保管後の外観にも優れていた。ビーグル犬における薬物動態試験においても良好な吸収を示す。
実施例6は、実施例1のポリオキシル35ヒマシ油の代わりに、ポリオキシエチレン硬化ヒマシ油であるHCO-60を使用し、加えて、その他成分を含めて配合比を変更したものである。ピタバスタチンカルシウムが完全に溶解し、医薬組成物の外観が良好であった。自己乳化性にも優れていた。また、過酷条件保管後の外観にも優れていた。ビーグル犬における薬物動態試験においても良好な吸収を示す。
実施例7は、ロスバスタチンカルシウムを用いて、ピタバスタチンカルシウム以外は実施例3と同一の成分について、実施例3に近似する配合比にて検討したものである。ロスバスタチンカルシウムが完全に溶解し、医薬組成物の外観が良好であった。自己乳化性にも優れていた。また、過酷条件保管後の外観にも優れていた。ビーグル犬における薬物動態試験においても良好な吸収を示す。
実施例8は、ロスバスタチンカルシウムを用いて、ピタバスタチンカルシウム以外は実施例6と同一の成分について、実施例6に近似する配合比にて検討したものである。ロスバスタチンカルシウムが完全に溶解し、医薬組成物の外観が良好であった。自己乳化性にも優れていた。また、過酷条件保管後の外観にも優れていた。ビーグル犬における薬物動態試験においても良好な吸収を示す。
参考例2の自己乳化組成物375mg(EPA-Eとして300mg)を充てんしたソフトゼラチンカプセルを、ロータリー法により製造した。本法により製造した自己乳化型カプセル製剤は、カプセル皮膜の変形等は認められなかった。
参考例2のカプセル製剤について、硬度を測定した。また、40℃相対湿度75%で1、2、4週間保管した製剤について、同様に硬度を測定した。
参考例2の製剤の初期、40℃ 1、2、4週間保管した場合の硬度(kgf)は、28.9、25.5、24.5および27.4であった。なお、初期とはカプセルの製造後、評価するまで室温で保管した製剤をいう。また、製剤はアルミ包装に密封して40℃に保管したため、湿度の影響は受けていない。
ここで記載するカプセルの硬度とは、一般的な硬度計により硬度を測定することで確認することができる。
参考例1のカプセルをヒト(20~40歳で体重55.0~77.0kg、BMI18.5以上25.0未満の健康成人男性)12例に絶食条件下で経口投与し、EPAの血中濃度の推移を評価した。各ヒトにはEPA-Eとして1800mgとなる量の自己乳化組成物を朝空腹時に水200mLを用いて単回経口投与した。投与後0.5、1、1.5、2、3、4、5、6、7、8、9、10、12、15、18、24、48および72時間に採血を行った。採血後、直ちに氷冷して、4℃、2000×gで10分間遠心分離し、血漿を分取して-20℃以下で凍結保存した。得られた血漿中のEPA濃度をLC/MS/MS(サンプルを液体クロマトグラフィーで分離し、それを質量分析で分離して測定する方法)により測定した。
また、参考例1のカプセルを食直後条件下でも経口投与し、同様に測定した。
また、対照群としてカプセルに充填したEPA-E原液(参考例1の自己乳化組成物と同じEPA-E用量であり、乳化剤等を含まない高純度EPA-E(96.5質量%以上)をいう)をヒト(20~40歳で体重55.0~77.0kg、BMI18.5以上25.0未満の健康成人男性)12例に絶食条件下で経口投与し、同様に測定した。
表2には試験結果より算出した最高血漿中濃度(Cmax)、投与後24時間の血漿中濃度(C24)、0時間から72時間までの血中濃度曲線下面積(AUC0-72)、最高血漿中濃度到達時間(Tmax)、血漿中消失半減期(t1/2)を示す。なお、各パラメーターの算出の際には各血中濃度より投与前の血漿中EPA濃度を減じた補正を行っている。
試験例8-1のEPA-Eの投与量を3600mgとした試験を同様に実施した。なおヒト6例に対して実施した。表3には試験結果より算出した最高血漿中濃度(Cmax)、投与後24時間の血漿中濃度(C24)、0時間から72時間までの血中濃度曲線下面積(AUC0-72)、最高血漿中濃度到達時間(Tmax)、血漿中消失半減期(t1/2)を示す。なお、各パラメーターの算出の際には各血中濃度より投与前の血漿中EPA濃度を減じた補正を行っている。
本発明の医薬組成物は、多価アルコール非添加または添加濃度が低いため、流通過程や保存中における多価アルコールが原因のカプセル軟化、変形が起こらず、品質変化のリスクが低い。
或いはまた、低温又は高温環境下の保存でも医薬組成物が白濁、分離等の変性のないことから、医薬として用いられる場合に寒冷地や高温地での保管可能な品質を有する。
