Description
W30=温度25℃における平衡相対湿度30%に対応する試料重量、
W10=温度25℃における平衡相対湿度10%に対応する試料重量である。
固定化酵素の調製
国際公開第9212782号パンフレットに記載されたようにして大腸菌ペニシリンアシラーゼを分離し、イオン交換クロマトグラフィーを用いて精製し、欧州特許出願公開第222462号明細書および国際公開第9704086号パンフレットに記載されたようにして固定化した。
162.2gの6−APA(6−アミノ−ペニシラン酸)および184.8gのHPGM(D(−)−p−ヒドロキシフェニルグリシンメチルエステル)を、450mlの水に懸濁させた。懸濁液を、10℃の温度まで冷却した。この反応混合物に、32850単位の固定化ペニシリンアシラーゼを加え、水を加えて最終容積を1500mlにした。この混合物を6時間かき混ぜた。反応中pHは6.9に上昇し、反応の終わりにはpHは6.2に下がった。この混合物に750mlの水を加え、(メッシュが100マイクロメートルの)篩いで懸濁液を2時間かけて濾過し、固定化酵素を分離した。アモキシシリン三水和物結晶を含有する、得られた懸濁液を0℃に冷却した。懸濁液は、アモキシシリン三水和物に対して50ppm未満のタンパク質(1,000,000重量部のアモキシシリン三水和物当り50重量部未満のタンパク質)を含有していた。
粒度分布(d10およびd50を含めて)を、対物レンズf=300mm、malvern試料測定ユニットPS1、およびMalvern乾燥粉末フィーダーPS64を有する、Malvern粒径測定器2600Cを用いて測定した。ビーム長は14.30mmであった。多分散分析モデルを用いた。
VTI−SGA 100蒸気収着分析装置を用いて、動的蒸気収着を用いて吸着等温線を求めた。重量200mgの試料を用いた。試料チャンバー内の空気を相対湿度10%で90分間コンディショニングした。その後、10%刻みで相対湿度を上昇させ、各値の相対湿度に試料を90分間保持した。90分後の試料重量を平衡相対湿度に対応した試料重量として用いた。温度は25℃とした。
上記の方法を用いて1バッチのアモキシシリン三水和物結晶性粉末を調製した。吸着等温線、ならびに粒度分布を測定した。図1に吸着等温線を示す。d50およびd10を表に示す。
アモキシシリンを調製する化学的方法で、希HClおよびイソプロパノール中にアモキシシリンを含有する溶液を得た。この溶液を撹拌槽に送った。温度20℃でpHを3.7に保持した。その後、NaOHを加えてpHを5.0に上げた。得られた混合物を、1から5℃で3から12時間容器内に保持する。このアモキシシリンを、遠心分離機を用いて分離し、流動床乾燥機を用いて乾燥した。
実施例Iの方法で得られたアモキシシリン三水和物粉末を、水分活性0.15まで乾燥する。この粉末を、4対1の重量比でクラブラン酸カリウムと混合する(無水アモキシシリンとクラブラン酸として計算した)。この混合物は安定である。
実施例Iの方法で得られたアモキシシリン粉末を、水分活性0.2まで乾燥する。この粉末を、4対1の比でクラブラン酸カリウムと混合する。この混合物は安定である。
実施例Iの方法で得られたアモキシシリン粉末を、水分活性0.15まで乾燥する。この粉末を、4対1の比でクラブラン酸カリウムと混合する。この混合物は安定である。
乾燥を、円錐形の真空接触式乾燥機(Vrieco−Nauta)を用いず、材料に機械的衝撃を与えない乾燥機(Ventilation stove)を用いて行った点を変えて実施例Iを繰返した。乾燥は、35℃の温度で16時間行った。d50およびd10は、それぞれ66.3μmおよび17.4μmである。嵩密度およびタップ密度は、それぞれ0.25g/mlおよび0.47g/mlである。
実施例Iに従ってアモキシシリン三水和物粉末の別のバッチを調製した(d50およびd10はそれぞれ61μmおよび19μmであり、嵩密度およびタップ密度はそれぞれ0.58g/mlおよび0.79g/mlである)。このバッチを風力篩い別け(Hosakawa Alpine製の風力篩200LS−N)にかけた。篩い別けは、75μmのスクリーンを用いて10分間行った。前記篩い別け中に生成した少量の凝集物を、振動篩(425μm)を用いて篩上分(篩いを通過しなかった部分)から取除き、その後得られた篩上分の結晶のタップ密度、嵩密度、d50、d10を測定した。d50およびd10は、それぞれ88μmおよび36μmである。嵩密度およびタップ密度は、それぞれ0.59g/mlおよび0.74g/mlである。
