Abstract
Description
HPLC(液体高速クロマトグラフィー)として,島津製作所製Prominence(登録商標)を用いた。検出波長は,流速228nm,流速は0.8mL/minとし,移動相としてCH3CN:H2O=7:1のものを用い,内部標準としてトランス-スチルベン(trans-stilbene)10μg/mlを用いた。サンプリング溶液は,メタノール:水:CH3CN:H2O=10:7:3のものを用いた。カラムとして,東ソー社製TSKgel ODS-80Ts直径4.6mm長さ150mmのものを用いた。
カスケードインパクターとしてティシュエンヴァイラメンタル(Tisch Environmental)社製シリーズ290 マープルパーソナルカスケードインパクターを用いた。流量は,2l/分であり,サンプル量はブリスター換算で5~10回分であり,定量分析には,先に説明したHPLCを用いた。
ふるい目開きの異なる3種類のふるい(60,100,200メッシュ)を順に重ね,底部に容器を装着する。粉体(例えば200メッシュ以下)を最上段(60メッシュ)のふるいに2g供給し,一定時間ふるいを振動させる。
振動時間(T)は次式によって決める。
T=20+(1.6-W)/0.016 [sec] (2)
ここで,Wは動的みかけ密度と呼ばれ,次式によって計算する。
W={(P-A)C/100}+A [g/cm3] (3)
振動終了後,上段(60メッシュ)のふるい残量X[g],中段(100メッシュ)のふるい残量Y[g],下段(200メッシュ)のふるい残量Z[g]を測定し,次式により自己凝集度Gを算出する。
G=(X/2+3Y/10+Z/10)×100 (4)
このGが高いほど自己凝集性が高いことを示す。
担体乳糖,β2-刺激剤,細粒乳糖及びコルチゾール誘導体を混合容器内に添加した。その後,混合容器を1分間振盪した。ターブラー混合機を用いて46rpmの回転速度にて1時間混合を行った。
担体乳糖,細粒乳糖を混合・攪拌した後に,β2-刺激剤及びコルチゾール誘導体を混合攪拌した以外は実施例1と同様にして乾燥粉末組成物を得た。
比較例1: 相対標準偏差 10.5%
比較例2: 相対標準偏差 8.3%
実施例2では,有効成分を変えた場合に,本発明が有効であるか否か検討した。実施例1においてキシナホ酸サルメテロール(SX)の替わりにテバAPI社製フマル酸ホルモテロール(FF)(粒径(D50)が5μm以下)を用い,プロピオン酸フルチカゾン(FP)の替わりにテバAPI社製ブデソニド(粒径(D50)が5μm以下)を用いた以外は実施例1と同様にして吸入用パウダーを製造した。そして,実施例1の吸入用パウダー及び実施例2の吸入用パウダーの分散性についてカスケードインパクター用いてFPF(Fine Particle Fraction)を評価した。
実施例3-1.実施例1において,担体乳糖に替えてロケット社製マンニトール(粒径(D50)が60μm)を用い,細粒乳糖に替えてロケット社製マンニトール(粒径(D50)が5μm以下)を用いた以外は実施例1と同様にして吸入用パウダーを製造した。
実施例4-1.実施例1において,細粒乳糖に替えてロケット社製マンニトール(粒径(D50)が5μm以下)を用いた以外は実施例1と同様にして吸入用パウダーを製造した。
