局所的薬剤学的製剤の薬物動力学の調査
本発明の局所的薬剤学的製剤の薬物動力学パラメーターと経口形との比較
例A
[14C]ロフルミラストを含有している、例7に相当する製剤及び例8に相当する製剤を、サイズ4cm2でラットの皮膚の毛を剃った領域(5匹の雄のウィスターラット)に適用した。放射能濃度を1h、4h、8h、24h後に血漿中で及び尿(0〜24h)中で測定した(n=5)。用量は1.7mg/kgであった。
結果:
例7の製剤:Cmax:0.214mg当量/l、AUC(0-24h):4.13(mg当量/l×h)
例8の製剤:Cmax:0.214mg当量/l、AUC(0-24h):3.99(mg当量/l×h)
1mg/kgに標準化した結果は次の通りである:
例7の製剤:Cmax:0.126、AUC:2.43
例8の製剤:Cmax:0.126、AUC:2.35
1mg/kgの経口投与後の動力学的パラメーターとの比較:
Cmax:0.225mg当量/l、AUC(0-24h):3.10(mg当量/l×h)
AUC(例7の製剤)とAUC(経口)との比は78%であり、かつAUC(例8の製剤)とAUC(経口)との比は76%である。
例7の製剤:用量の19.4%
例8の製剤:用量の18.0%
経口投与:用量の18.4%
結論:
ラットへの[14C]ロフルミラスト1.7mg/kgの経皮投与後に、全放射能は皮膚を通して十分に輸送され、使用された製剤に関係なく4h後に0.214mg当量/lの最大血漿レベルに達する。経皮投与後の全放射能、AUCs及び尿での排泄に基づいて経口投与後のそれとは取るに足るほど違わない。
例B
[14C]ロフルミラストを含有している例5に相当する製剤を、サイズ4cm2でラットの皮膚の毛を剃った領域(雄のウィスターラット)に適用した。放射能濃度を、1h、4h、8h、24h後に血漿中で及び尿(0〜24h)中で測定した(n=5)。用量は1.77mg/kgであった。
例5の製剤:Cmax:0.331mg当量/l、AUC(0-24h):4.99(mg当量/l×h)
1mg/kgに標準化した結果は次の通りである:
例5の製剤:Cmax:0.187、AUC:2.82
1mg/kgの経口投与後の動力学的パラメーターとの比較:
Cmax:0.225mg当量/l、AUC(0-24h):3.10(mg当量/l×h)
尿での排泄の比較結果:
例5の製剤:用量の22.0%
経口投与:用量の18.4%
結論:
これらのデータは、ロフルミラストが、例7又は8に相当する製剤からよりも、幾分より一層良好に例5の製剤から吸収されることを示している。投与後24h内の尿での排泄は22%であり、これは例7又は8に相当する製剤の皮膚投与後の尿での排泄の範囲内でもある。経口投与との比較は、局所製剤の組成に関係なく、類似のCmax及びAUCs及び類似の尿での排泄が達成されることを示している。
