甘味剤としてスクラロース、キシリトール、またはソルビトールを用いて官能試験および懸濁液の安定性評価を行った。甘味剤の含量は甘味度(スクラロース:600,キシリトール:1,ソルビトール:0.8)を参考に各製剤が同程度の甘みになるように設定した。
(1)顆粒剤の製造方法
流動層造粒乾燥機(S2-B5-F2,Aeromatic Fielder AG社)に表1-1に記載の処方の重量比に従って、エドキサバントシル酸塩水和物、D-マンニトール、部分アルファー化デンプン、クロスポビドン、甘味剤、およびカルメロースナトリウムを投入し、ヒドロキシプロピルセルロースおよびストロベリーフレーバーを精製水に溶解した液を噴霧することによって造粒した後、乾燥することによって比較例1-1および1-2、ならびに実施例1-1~1-3の顆粒剤を得た。
官能評価:上記方法により製造した比較例1-1および1-2、ならびに実施例1-1~1-3の顆粒剤をヒトに投与し、その味、ならびに投与直後および投与から2~5分後の満足度を5段階(1:とても嫌い,2:嫌い,3:わからない,4:好き,5:とても好き)で評価した。評価の結果、その平均値が4点を越えたものに関して○、下回ったものに関して×を表1-2に記載した。
懸濁液の安定性評価:表1-1に記載の処方に従って25mL褐色ガラス瓶(Code:0755,Gerresheimer社)にエドキサバントシル酸塩水和物、D-マンニトール、部分アルファー化デンプン、クロスポビドン、ヒドロキシプロピルセルロース、甘味剤、CMC-Na、およびストロベリーフレーバーを秤量した後に混合した。エドキサバンの理論含量として6mg/mLとなるように水を加えた。混合物を振とうし、懸濁液を調製した後、調製直後、5分後、15分後、30分後に懸濁液の液面から1cmの位置より1mLのサンプルを採取し、エドキサバンの濃度をHPLC(AGILENT 1100,1200,または1260;AGILENT社)により評価した。濃度の経時変化が全評価時点において90%~110%の範囲内であったものに関しては表1-2に○と記載し、経時変化が上記の範囲を超えたものを×と記載した。
官能評価および懸濁液の安定性評価の結果を表1-2に示す。実施例1-1~1-3のように甘味剤としてキシリトールまたはソルビトールを用いた際には官能評価の結果、服用に際して製剤の味が障害とはならないことが分かった。また、実施例1-1~1-3の顆粒剤は懸濁液中のエドキサバンの濃度の変化が90%~110%であることがわかった。すなわち、CMC-Naとキシリトールまたはソルビトールの組み合わせを採用した顆粒剤は懸濁液の安定性が高く、本発明の顆粒剤として適した性能を有することが分かった。
以下に記載する1顆粒法および2顆粒法による本発明の顆粒剤の製造方法を検討した。
(1)1顆粒法による顆粒剤の製造方法
表2-1に記載の処方の重量比に従って、実施例1と同様の方法により、比較例2-1~2-5の顆粒剤を製造した。
第一顆粒(薬物含有顆粒)の製造:表2-1に記載の処方の重量比に従って、流動層造粒乾燥機(S2-B5-F2,Aeromatic Fielder AG社)にエドキサバントシル酸塩水和物、D-マンニトール、部分アルファー化デンプン、およびクロスポビドンを投入し、ヒドロキシプロピルセルロースを精製水に溶解した液を噴霧した後、乾燥することによって第一顆粒(薬物含有顆粒)を得た。
上記方法で得られた比較例2-1~2-5、および実施例2-1~2-4の顆粒剤をメスフラスコに秤量し、アセトニトリルと水の混合溶媒(3:7(v/v))でメスアップし、振とうおよび超音波を当てることにより完全に溶解させた。得られた溶液から一部を採取し、理論量としてエドキサバントシル酸塩水和物を80.8μg/mL含むように希釈することによって評価用溶液を調製した。別途、エドキサバントシル酸塩水和物の標準溶液を調製し、HPLCを用いて評価用溶液中のエドキサバントシル酸塩水和物の含量を測定し、理論含量に対する実含量の割合(含量%)を算出した。
1顆粒法および2顆粒法の製造方法に従って製造した顆粒剤についてエドキサバンの含量を測定した結果を表2-2および表2-3に示した。その結果、1顆粒法で製造した比較例2-1~2-5の顆粒剤においてはエドキサバンの含量が低下することが分かった。この含量低下は、1顆粒法では造粒工程中に原料の大部分を占めるキシリトールが吸湿し、その一部が原薬とともに壁面およびバグフィルターへ付着することに起因する可能性が示唆された。一方、2顆粒法では吸湿性のあるキシリトールと原薬のエドキサバンを別々の顆粒にして製造することにより、原薬の製造機器内部への付着が抑制され、この問題が解決された。すなわち、2顆粒法で製造した実施例2-1~2-4の顆粒剤はエドキサバンの含量が低下しないことが分かった。
前記1顆粒法および2顆粒法で製造した顆粒剤について溶出試験を行って製法の異なる顆粒剤の溶出性能を比較した。
(1)顆粒剤の製造方法
実施例2の(1)に記載の1顆粒法による顆粒剤の製造方法、実施例2の(2)に記載の2顆粒法による顆粒剤の製造方法、および表2-1に記載の処方の重量比に従って、比較例3-1(1顆粒法)および実施例3-1(2顆粒法)の顆粒剤を製造した。
溶出試験法
pH6.0のリン酸緩衝液を用い、欧州薬局方に記載の方法(パドル法:毎分50回転)に従って溶出試験を行った。
1顆粒法によって製造した比較例3-1、および2顆粒法によって製造した実施例3-1の顆粒剤の溶出試験の結果を図1に示す。1顆粒法で製造した顆粒剤は高い溶出性を示したが、実施例2の結果から分かるように、エドキサバンの含量が低下しており、溶出率が100%とはならなかった(すなわち理論含量まで到達しなかった)。一方、2顆粒法で製造した顆粒剤は高い溶出性を示し、またエドキサバンの含量の低下がないことから優れた製剤であることが分かった。
第一顆粒と第二顆粒の粒子径の検討を行い、偏析を起こさない顆粒剤の条件を探索した。
(1)製造方法
実施例2の(2)に記載の2顆粒法による製造方法および表2-1に記載の処方の重量比に従って第一顆粒および第二顆粒を製造した後、整粒機(QC-197s,Quadro Comil,Quadro社)を用いて整粒操作を行うことによって、第一顆粒に関してそのメジアン径(X50)が137、177、もしくは212μmの顆粒を、また、第二顆粒に関してそのメジアン径(X50)が179、181、もしくは234μmの顆粒を得た。上記第一顆粒および第二顆粒の粒度分布はふるい分け振とう機(AS200,Retsch GmbH製)を用いたふるい分け法により測定し、累積50%粒子径(X50;メジアン径)を算出した。
次に顆粒剤の総量が約10kgのスケールで表4-1に記載の第一顆粒および第二顆粒の粒子径の組み合わせに従って第一顆粒と第二顆粒の混合条件の検討実験を行った。第一顆粒が14.4重量%、および第二顆粒が85.6重量%の割合になるように上記方法により得られた顆粒をビン型混合機(Limitec GmbH製)に投入し、毎分6回転で20分間混合することによって実施例4-1~4-3に記載の顆粒剤を製造した。
・混合均一性
上記の実施例4の(1)に記載の製造方法においてビン型混合機で混合を開始してから10分、15分、20分後に、図2の模式図上に示した採取位置A~Jよりサンプルを採取した。得られたサンプルについてエドキサバンの含量を実施例2の(3)と同様の方法で測定し、その平均値と標準偏差を算出することによって混合均一性を評価した。
上記実施例4の(1)に記載の製造方法で製造した顆粒剤をボトル充填機(SW703,Collischan GmbH社)を用いて1ボトル当たり2.75g(エドキサバントシル酸塩水和物の理論量として80.8mg)充填した。ボトル充填工程中に時系列的に採取した10サンプルに関して、1ボトルに含まれるエドキサバンの理論含量に対する実含量の割合(含量%)を測定した。測定は実施例2の(3)と同様の方法で行い、平均含量、含量標準偏差を算出した。また、欧州薬局方に従い判定値を算出することで、製剤均一性を評価した。
第一顆粒と第二顆粒の粒子径の組み合わせをさまざまに変えて製造した実施例4-1~4-3の顆粒剤について、混合均一性および製剤均一性の結果を表4-1に記載した。実施例4-1は第一顆粒のX50が第二顆粒のX50よりも大きいことを特徴とする顆粒剤である。実施例4-2は第一顆粒のX50が第二顆粒のX50と同程度の大きさであることを特徴とする顆粒剤である。実施例4-3は第一顆粒のX50が第二顆粒のX50よりも小さいことを特徴とする顆粒剤である。実施例4-1~4-3において、10分、15分、20分の時点での標準偏差の値にばらつきが見られるが、これは均一性が定常に達した状態においてサンプリングに起因するばらつきが存在することを示唆している。実施例4-1~4-3における製剤均一性と混合終了時(混合開始から20分後)の混合均一性の標準偏差の値の大きさは同じ順序(実施例4-2<実施例4-3<実施例4-1)になっているが、その値を比較すると製剤均一性の値の方が混合均一性の値よりも小さくなっている。実施例4-1~4-3の製剤均一性の判定値は欧州薬局方の基準であるL1(15%)よりも小さくなっており、その基準を満たすことが分かった。
以上より、本発明により約10kgのスケールで各国の規制当局が求める基準を満たす顆粒剤を製造できることが明らかになった。
