本発明は以下を提供する。
[1]有効成分としてモサプリドまたはその塩を含有する、1日1回経口投与の徐放性または制御放出型製剤であって、
上記製剤は、胃腸管における滞留時間が18時間〜24時間であり、胃腸管を通過する際に、胃において20〜50%のモサプリドまたはその塩を溶出させ、腸管において50〜80%のモサプリドまたはその塩を溶出させるものであり、
有効成分、充填剤、崩解剤および添加剤を含む速放層と、
有効成分、充填剤、崩解剤、制御放出基剤および添加剤を含む徐放層を含み、
上記徐放層は、80,000cps〜120,000cpsの粘度を有する高粘度ヒドロキシプロピルメチルセルロース:2,000cps〜20,000cpsの粘度を有する低粘度ヒドロキシプロピルメチルセルロースの重量比が10〜1:1の範囲で混合される前記制御放出基剤として調製され、
前記徐放製剤は、大韓民国薬典溶出試験法第2法(パドル法)に基づいて37℃、pH 4.0、6.8、1.2の溶出液および水において測定された場合、下記溶出プロファイル:
1)pH 4.0、pH 1.2の溶出液および水の条件で、上記製剤に含まれた有効成分の溶出率が、1時間後に25〜45%、8時間後に60〜80%、24時間後に85%以上である
2)pH 6.8の溶出液の条件で、上記製剤に含まれた有効成分の溶出率が、16時間後に45%以下である
を満たすことを特徴とする、モサプリド含有経口投与製剤。
[2]高粘度ヒドロキシプロピルメチルセルロース:低粘度ヒドロキシプロピルメチルセルロースの重量比が2.6〜1:1であることを特徴とする、上記[1]に記載のモサプリド含有経口投与徐放製剤。
[3]総重量が200mg以下であることを特徴とする、上記[1]に記載のモサプリド含有経口投与徐放製剤。
[4]総重量が150mg〜160mgであることを特徴とする、上記[1]に記載のモサプリド含有経口投与徐放製剤。
[5]pH6.8の溶出液の条件で含まれた有効成分の溶出率が、24時間後に45%以下であることを特徴とする、上記[1]に記載のモサプリド含有経口投与徐放製剤。
[6]上記徐放層は、全徐放層100重量部に対し、モサプリドクエン酸塩14.11重量部、粘度が4,000cpsであるヒドロキシプロピルメチルセルロース10.67重量部、100,000cpsであるヒドロキシプロピルメチルセルロース18.67重量部、微結晶セルロース17.33重量部、乳糖水和物12.65重量部、低置換度ヒドロキシプロピルセルロース18.67重量部、ポリビニルピロリドン6.67重量部、軽質無水ケイ酸0.41重量部、ステアリン酸マグネシウム0.83重量部からなることを特徴とする、上記[1]に記載のモサプリド含有経口投与徐放製剤。
薬物は、胃腸管を通過しながら投与剤形から放出され、最終的には、溶解、吸収される。薬物が吸収されるためには、まず、吸収部位で体液中に溶出および溶解する。例えば、錠剤またはカプセル剤の形態で経口投与された薬物は、その薬物分子が胃腸管内で溶出および溶解されてはじめて吸収される。また、1日1回投与薬の場合、24時間持続的な効果を示すために、血中半減期が短いモサプリドまたはその塩は、20時間以上胃腸管内で滞在しながら、20時間以上溶出、溶解および吸収されることが好ましい。胃腸管内での滞留時間は、使用される製剤内の成分の種類および/または組成比によって調節することができる。
速放層の製造:表1および表2に記載された成分の含有量に応じて、モサプリドクエン酸塩と微結晶セルロース、乳糖水和物、低置換度ヒドロキシプロピルセルロース(L-HPC)を混合した後、予めエタノールに溶かしたポビドンK-30液を加えて混練および顆粒化し、キャビネット乾燥機で50〜60℃の温度で30〜40分乾燥させた(LOD 2%以下)。整粒した後、残りの滑沢剤を混合した。
市販されているガスモチン錠5mg(モサプリド5mg、大熊製薬)製剤と上記比較例1で製造した速放層のみからなる錠剤に対し、pH 4.0の溶出液における溶出様相を比較し、この時、大韓民国薬典一般試験法第2法に従って、パドルを50rpm/分で回転させたイン・ビトロ溶出試験を行った。その結果は、図1に示した。速放層のみからなる比較例1の場合、ガスモチン錠と類似して30分以内で100%の薬物が溶出された。
比較例2〜4のように、低粘度の徐放化基剤(HPMC2910)のみを用いて製造した錠剤の溶出率は、6時間が経過する以前に薬物が100%溶出して徐放化(sustain-release)を示さなかった(図2)。一方、比較例5および6のように高粘度の徐放化基剤(HPMC2208)のみを用いて製造した錠剤の溶出率は、24時間後も薬物が100%溶出されず、長い徐放化を示した(図3)。
臨床試験のための最終的な組成(formulation)として実施例3の徐放錠製剤を確定し、実施例4の徐放錠製剤の原料薬品の分量および構成比を表3に示した。
検体:実施例4のモサプリドクエン酸塩徐放錠製剤
溶出試験液:大韓民国薬局方崩壊試験法(pH 1.2、4.0、6.8の溶出液、水)900ml、
試験温度:37±0.5℃
溶出方法:大韓薬局方溶出試験第2法(パドル法)、1分当り50回転
In vitroの多様なpH条件で溶出様相を確認した実施例3のモサプリドクエン酸塩徐放錠製剤を有し、モサプリドクエン酸塩のpkを次のような事前-臨床テスト(Pre-clinical test)で確認した。
本発明の製剤の薬力学的同等性を評価するために、健康な男性被験者を対象に実施例3の組成を有するモサプリドクエン酸塩徐放錠製剤とモサプリド速放性製剤(ガスモチン5mg、大熊製薬)の経口投与時における薬物動態の特性および飲食物の影響を比較評価するための無作為割り当て、オープンラベル、単回、3治療群、3期ウィリアムズ設計第1相臨床試験を行った。被験者は、年齢が満20歳以上55歳以下であり、臨床試験計画書の選定および除外基準に基づいて選定された健康な男性ボランティア48人である。具体的な試験条件は以下の表6の通りであり、臨床試験の結果は、表7と図10に示した。
