Abstract
Description
しかしながら、ODTの場合、口腔内で完全に崩壊されて溶解されるまでは少なくとも30秒以上かかるのが普通であり、特に、崩壊が終わるまでは口腔内で激しい異物感を感じるため、水なしに服用可能であるとはいえ、実際にこれを服用する患者の服用し易さを大幅に高めることができなかった。
下記表1に従い、様々な有効成分をコーティング基剤および溶媒からなるコーティング溶液に溶解または分散させる。この液を糖または糖アルコールからなる球状のビード(粒径50〜400μm)を流動層コーティング装置において流動させながら(風の温度:50℃)先に製造された有効成分含有コーティング液を下方噴射方式でコーティングして結果物を得る。さらに、この結果物に糖または糖アルコールを混合して最終混合物を得る。
実施例1〜6に対応するものであり、高速混合機(High Speed Mixer)を用いて湿式顆粒状に製造した。具体的には、表2に示すように、有効成分とスクロース(200mesh)をよく混合してHSMに投入し、回転しながら結合液に溶かした結合剤を投入する。3分間高速で練り合わせた後に得られた結果物を20meshのオシレータで篩過し、60℃の熱風乾燥機で乾燥させる。得られた結果物を再び30meshのオシレータで篩過した後に後混合によりキシリトールを添加し、5分間混合して最終結果物を得る。
実施例1〜6に対応するものであり、高圧射出機(Extruder)を用いて湿式顆粒状に製造した。具体的には、表3に示すように、有効成分とスクロース200meshをよく混合してHSMに投入し、回転しながら結合液に溶かした結合剤を投入する。3分間高速で練り合わせた後に得られた結果物をドームスクリーンサイズ1mmのシングルドーム形高圧射出機で射出し、60℃の熱風乾燥機で乾燥させる。得られた結果物を再び30meshのオシレータで篩過した後に後混合によりキシリトールを添加し、5分間混合して最終結果物を得る。
実施例1〜6に対応するものであり、流動層顆粒機(Fluid Bed Granulator;FBG)を用いて湿式顆粒状に製造した。具体的には、表4に示すように、有効成分とスクロース(200mesh)をFBGで流動混合させる。コーティング基剤をコーティング溶液に溶解させた後に有効成分入り混合物をFBGで流動させながら(風の温度:50℃)コーティング液を上方噴射方式(Top Spray)で造粒して結果物を得る。さらに、この結果物に糖または糖アルコールを混合して最終混合物を得る。
前記実施例1〜6および比較例1〜18において製造した薬剤学的組成物に対して健常な成人20名を対象に口腔内で溶かしながら口腔内の異物感に対する官能評価を行った。このとき、全ての試験において試験対象者に盲検を維持した。その試験結果を下記の評価基準に基づき評価して示す。
1点:異物感が全くない。
2点:異物感があるようであるが、ほとんど感じられない。
3点:やや異物感がある。
4点:異物感があり、拒否感がある。
5点:異物感が非常に強い。
前記実施例1〜6および比較例1〜18において製造した薬剤学的組成物に対して健常な成人20名を対象に口腔内で溶かしながら口腔内の残留感に対する官能評価を行った。このとき、全ての試験において試験対象者に盲検を維持した。その試験結果を下記の評価基準に基づき評価して示す。
前記実施例1〜6および比較例1〜18において製造した薬剤学的組成物に対して健常な成人20名を対象に口腔内で溶かしながら口腔内の溶解速度を測定した(単位:秒)。このとき、全ての試験において試験対象者に盲検を維持した。
前記実施例1〜6および比較例1〜18において製造した薬剤学的組成物を5cmx7cmの大きさの6列小袋包装機を用いてそれぞれ100列を包装した。これらの中で、真ん中にある第3列目の検体10個をとり、包装紙内の薬物を一気に空けた。微粉がついた包装紙の重さを測定した後、包装紙内に残留する中身を全て除去した後に、再び微粉のない包装紙の重さを計って全体の中身の割合で示す(単位:%)。
前記実施例1〜6および比較例1〜18において製造した薬剤学的組成物を5cmx7cmの大きさの6列小袋包装機を用いてそれぞれ100列を包装した。これらの中で、ランダムに検体10個をとり、薬典一般試験法の製剤均一性試験のうち、含量均一性試験法に従って中身の含量を測定した。検体の含量の標準偏差を求め、検体10個のときの判定係数(k)2.4を乗じて含量均一性に対する判定値を求めた。下記表33〜36に各検体の測定結果を示す。
