The present invention relates to a method for the production of a nanoparticulate pharmaceutical composition. The method comprises the steps of a) suspending in water a poorly soluble active ingredient without the presence of a detergent, b) mechanically treating said suspension to obtain particles comprising the active ingredient with an effective average size of less than about 5000 nm, c) contacting said active ingredient or suspension with a first polyelectrolyte during and/or before mechanically treating, d) optionally contacting said suspension with a one or more second or further polyelectrolytes during, before and/or after mechanically treating, e) optionally drying said suspension. The invention also pertains to the pharmaceutical compositions obtained by the method of the invention.
本发明涉及一种生产纳米颗粒药物组合物的方法。该方法包括以下步骤:a) 将溶解性差的活性成分悬浮于
水中,且不含洗涤剂;b) 对所述悬浮液进行机械处理,以获得包含有效平均粒径小于约 5000 nm 的活性成分的颗粒;c) 在机械处理过程中和/或之前,将所述活性成分或悬浮液与第一种聚电解质接触;d) 在机械处理过程中、之前和/或之后,选择性地将所述悬浮液与一种或多种第二种或更多的聚电解质接触;e) 选择性地干燥所述悬浮液。本发明还涉及通过本发明方法获得的药物组合物。
