Abstract
Description
詳細には、本発明は、タムスロシン、ハイドロゲル形成高分子物質、及び親水性基剤からなる放出制御部と、ソリフェナシン、及び親水性物質からなる速放部とを単一製剤中に含有してなる経口投与用医薬組成物に関するものである。
従来の徐放製剤よりもピーク/トラフ比の小さい血中薬物濃度推移を示す製剤を提供し、起立性貧血などの潜在的な副作用発現を抑制するとともに、投与量増加の可能性や長時間にわたり安定な薬効を発現する可能性を示す。また、食事の摂取による血中薬物濃度への影響も受けにくくなり、服用コンプライアンスの観点からも高い安全性が期待される(特許文献5)。
特にハイドロゲルを形成する高分子物質を含有してなる放出制御部内に、水に『溶けやすい』ソリフェナシンが溶解し、取り込まれるなどの可能性がある事自体が、予想外なことである。
そこで本発明者らは、特にソリフェナシンの放出速度と最大溶出率の改善に注目して、鋭意検討を行った結果、本願発明を完成させるに至った。
