    • The present invention relates to a production method for a powder containing nanoparticles of an insoluble drug, a powder produced thereby, and a pharmaceutical composition containing the same. The method comprises the steps of: providing a uniformly dispersed solution of an insoluble drug which has been formed into nanoparticles in the presence of a surface stabilizer; mixing the uniformly dispersed solution with a water-soluble dispersant solution; and drying the resulting mixed solution and thereby recovering a powder. When the powder containing the nanoparticles of the insoluble drug obtained by the method of the present invention is again dispersed in an aqueous solution, the insoluble drug retains a particle size in the nano scale while the solubility and the dissolution rate of the drug are increased, thereby providing enhanced bioavailability. Consequently, the present invention can be used effectively in the development of otherwise insoluble drug preparations for oral or parenteral administration.
    • 本发明涉及一种含有不溶性药物的纳米颗粒的粉末的生产方法,由此制备的粉末和含有它的药物组合物。 该方法包括以下步骤:提供在表面稳定剂存在下已形成纳米颗粒的不溶性药物的均匀分散溶液; 将均匀分散的溶液与水溶性分散剂溶液混合; 并干燥得到的混合溶液,从而回收粉末。 当通过本发明方法获得的含有不溶性药物的纳米颗粒的粉末再次分散在水溶液中时,不溶性药物保持纳米级的粒径,同时药物的溶解度和溶解速率增加, 从而提供增强的生物利用度。 因此,本发明可以有效地用于开发用于口服或肠胃外给药的其它不溶性药物制剂。
