(2)有機酸が、コハク酸、酒石酸、及びクエン酸からなる群より選択される一種又は二種以上の成分である前記(1)記載の薬物含有造粒物、
(3)有機酸の配合量が、エドキサバン100質量部に対して0.1〜30%である前記(1)〜(2)のいずれかに記載の薬物含有造粒物、
(4)エドキサバン、その薬理上許容される塩、又はそれらの水和物が、エドキサバントシル酸塩水和物である、前記(1)に記載の薬物含有造粒物、

エドキサバントシル酸塩水和物4.04g(エドキサバンとして3.0g)、D−マンニトール(Roquette製:PEARLITOL 50C)8.74gを混合後、ヒドロキシプロピルセルロース(日本曹達:HPC−SSL)0.02gを精製水1gに溶解させた結合剤溶液を滴下し造粒する。造粒終了後、棚乾燥機を用いて乾燥させ、目開き1.0mmの篩にて篩過し、薬物含有整粒末(有機酸を含有しない比較例の薬物含有造粒物)を得た。
実施例1〜4で得られた薬物含有造粒物130mg、比較例1で得られた薬物含有造粒物128mgを用いて溶出試験を行った。薬物含有造粒物の溶解は溶出試験器(富山産業製)においてパドル法にて50rpm、pH6.8緩衝液900mL中で行った。試験開始から60分後まで経時的にサンプルを20mL抜き取り、孔径0.45μmのメンブランフィルターでろ過し、ろ液についてUV測定法により波長260nmにおける吸光度から溶出率を算出した。測定結果を表2に示す。
流動層造粒乾燥機(パウレック製:FM−MP−01)を用いてD−マンニトール(Roquette製:PEARLITOL 50C)336g、結晶セルロース(旭化成製:KG−1000)168g、クロスポビドン(BASFジャパン製:Kollidon CL−F)32gを混合し、α化デンプン(旭化成製:PD−1)24gを精製水276gに分散させた結合剤溶液を噴霧して造粒及び乾燥終了後、目開き0.71mmの篩にて篩過し、薬物不含有造粒物を得た。
(口腔内崩壊錠の作製)
実施例1で得られた薬物含有造粒物6.5g及び薬物不含有造粒物3.35gにスクラロース(三栄源エフ・エフ・アイ製:スクラロース(P))0.05g、三二酸化鉄0.002g(VENATOR製:三二酸化鉄)、及びフマル酸ステアリルナトリウム(JRS Pharma製:PRUV)0.1gを添加して混合し打錠末を調製し、ステアリン酸マグネシウム(太平化学産業製:ステアリン酸マグネシウム(植物性))を外部添加して打錠を行い、錠剤質量200mg、φ8mmの円形錠として本発明の口腔内崩壊錠を得た。
