デンプングリコール酸ナトリウム、クロスポビドンおよびポリビニルピロリドンを、それぞれ♯20メッシュを通過させてV型混合器で30分間混合した。次いで、これにステアリン酸マグネシウム(滑沢剤)を適量添加し5分間混合して、得られた混合物をロータリ打錠器(セジョンパーマテク社、MRC−45)を用いて約20kNの圧縮力で打錠し、ロサルタン100mg−アムロジピン5mg複合錠剤を製造した。
15mgのクロスポビドンの代わりに、15mgのクロスカルメロースナトリウムを用いたことを除いては、実施例1と同様の工程を行って複合錠剤を製造した。このようにして得られた製剤の平均硬度と摩損度は、それぞれ18.5kp及び0.0%であり、これによって錠剤の強度が良好であることが分かる。
デンプングリコール酸ナトリウムとクロスポビドンをそれぞれ25mgの量で用いたことを除いては、実施例1と同様の工程を行って複合錠剤を製造した。このようにして得られた製剤の平均硬度と摩損度は、それぞれ15.3kp及び0.2%であり、これにって錠剤の強度が良好であることが分かる。
15mgのクロスポビドンの代わりに25mgのクロスカルメロースナトリウムを用いて、デンプングリコール酸ナトリウムを25mgの量で用いたことを除いては、実施例1と同様の工程を行って複合錠剤を製造した。このようにして得られた製剤の平均硬度と摩損度は、それぞれ14.5kp及び0.1%であり、これによって錠剤の強度が良好であることが分かる。
15mgのデンプングリコール酸ナトリウムの代わりに25mgのクロスカルメロースナトリウムを用いて、クロスポビドンを25mgの量で用いたことを除いては、実施例1と同様の工程を行って複合錠剤を製造した。このようにして得られた製剤の平均硬度と摩損度は、それぞれ17.1kp及び0.1%であり、これによって錠剤の強度が良好であることが分かる。
デンプングリコール酸ナトリウムとクロスポビドンをそれぞれ25mgの量で用いて、クロスカルメロースナトリウムを25mgの量で追加して用いたことを除いては、実施例1と同様の工程を行って複合錠剤を製造した。このようにして得られた製剤の平均硬度と摩損度は、それぞれ11.7kp及び0.3%であり、これによって錠剤の強度が良好であることが分かる。
デンプングリコール酸ナトリウムとクロスポビドンをそれぞれ40mgの量で用いたことを除いては、実施例1と同様の工程を行って複合錠剤を製造した。このようにして得られた製剤の平均硬度と摩損度は、それぞれ11.2kp及び0.2%であり、これによって錠剤の強度が良好であることが分かる。
ロサルタンカリウムを50mgの量で用いたことを除いては、実施例1と同様の工程を行って、ロサルタン50mg−アムロジピン5mgの複合錠剤を製造した。このようにして得られた製剤の平均硬度と摩損度は、それぞれ16.9kp及び0.3%であり、これによって錠剤の強度が良好であることが分かる。

試験例1:アムロジピン溶出試験
実施例1乃至8及び比較例1乃至5から得られたアムロジピン-ロサルタン複合製剤のそれぞれに対して、下記の条件で薬物溶出試験を行った。その結果を下記表2に示す。
溶離液:人工胃液(pH 1.2)900ml
溶出試験システム:USPパドル法、50rpm
温度:37℃
−分析条件−
カラム:5μm液体クロマトグラフィー用オクタデシルシリル化シリカゲルで充填されたステンレス鋼カラム(内径4.6mm、長さ15cm)
移動相:メタノールと0.03Mリン酸二水素カリウムとの混合物(600:400、 v/v)
検出器:紫外分光光度計(350nm)
流速:1.5 ml/分
注入量:20μl
(2)60分後のアムロジピン溶出率(%)
上記表2に示すように、実施例1から実施例8で得られた複合錠剤の、30分後及び60分後のアムロジピン溶出率はそれぞれ75%以上及び90%以上である一方、比較例1から比較例5で得られた錠剤の場合は遥かに低いアムロジピン溶出率を示した。特に、比較例2から得られた錠剤は4.7kPの低い硬度を持っているにも拘らず、30分時点で60%にも及ばない低いアムロジピン溶出率を示した。
実施例3及び4、並びに比較例1及び5から得られた複合錠剤及びコザール錠(商品名)100mgのそれぞれに対して、下記の条件下において薬物溶出試験を行った。その結果を図1及び図2に示す。
溶離液:人工胃液(pH 1.2)または0.01N HCl(pH 2.0)900ml
溶出試験システム:USPパドル法、50rpm
温度:37℃
−分析条件−
カラム:5μm液体クロマトグラフィー用オクタデシルシリル化シリカゲルで充填されたステンレス鋼カラム(内径4.6mm、長さ15cm)
移動相:
移動相A−リン酸緩衝液:アセトニトリル(850:150、v/v)
移動相B−アセトニトリル
濃度勾配(gradient)システム(表3)
流速:1.5ml/分
注入量:10μl
−結果−
上記溶出試験システム(USPパドル法、50rpm)は、経口製剤用薬物の溶出率を測定するのに最も広く用いられており、また、用いられた溶離液(人工胃液(pH1.2)または0.01N HCl(pH 2.0))は胃腸管のpHと類似するpHを持つ。
