Description
本出願は、1999年12月20日出願の米国仮特許出願第60/172573号の米国特許法第119条第e項の利益を主張する2000年12月19日出願の国際出願第PCT/US00/34606号の国内段階である米国特許出願第10/168520号の一部継続である。
本発明は、医薬、食品及び化粧品の用途分野において有用な化合物のナノ粒子を製造するための方法に関する。特に、本発明は、溶媒と溶質を含有する溶液を空のチャンバー中で噴霧乾燥させてナノ粒子を形成する技術を利用したナノメートル粒子の製造に関する。
(Σnd4)/(Σnd3)
ここで、n=直径「d」によって特徴付けられるサイズ間隔中の粒子数。
水不溶性化合物をメタノール/アセトンの混合物に溶解させた。3、5、又は15%w/vの化合物として3通りの化合物濃度とした。その溶液を、ウルスター型底部スプレーを装備したFluidAirの研究室規模の流動床システムModel 002中に噴霧した。入口空気温度は約66−83℃に維持した。プロセス中において、出口空気温度をモニターし記録したところ、26−34℃の範囲であった。噴霧速度は2.2−4.8グラム/分の範囲であった。空気噴霧圧は30psiに維持した。3種の得られた材料は、それぞれ3、5、及び15%w/v噴霧溶液に対して772、769、及び777ナノメートルの平均粒径(平均直径)を有していた。
上記の化合物を、溶媒としてメタノール/アセトン中に溶解させ、成分、ラウリル硫酸ナトリウム(7%w/v)及びヒプロメロース(1%w/v)を加えて、その化合物の5%w/v溶液を得た。同じプロセス条件を維持したところ、得られた材料は743ナノメートルの平均粒径を有していた。その材料は水にさらしたとき高い分散性と湿潤特性を示していた。
アトルバスタチンをメタノール及び0.6%w/vのドキュセートナトリウムに溶解させた。その溶液を、実施例1及び2に記載したものと本質的に同じプロセス条件を使用して噴霧した。得られた材料は733ナノメートルの平均粒径を有していた。
噴霧乾燥した化合物粉末を、伝統的な手順によって処方した同じ化合物の製剤と比較して、イヌにおけるそのバイオアベイラビリティについて試験した。最大血漿中濃度及び曲線下血漿面積(plasma area-under-the-curve)濃度に基づいて、ナノ粒径の噴霧乾燥化合物のバイオアベイラビリティは伝統的な(微粒子化)製剤のものより優れていることが測定された。
