The invention relates to new compositions of poorly soluble or water insoluble drugs and to compositions of relatively soluble drugs which have a tendency to agglomerate or crystallise in storage or after formulation into pharmaceutical dosage form. The new compositions provide higher dissolution rates of said drugs in vitro and increased bioavailability. The compositions of this invention comprise such poorly soluble, water insoluble or relatively soluble drugs, a non-toxic water soluble polymer and a wetting agent. A process for preparing the compositions is also disclosed. Compositions containing the known antifungal griseofulvin illustrate the invention.
本发明涉及溶解性差或不溶于
水的药物的新组合物,以及在储存过程中或配制成药物剂型后容易结块或结晶的相对溶解性药物的组合物。新组合物可提高上述药物在体外的溶解速率,并增加
生物利用度。本发明的组合物由此类溶解性差、不溶于
水或溶解性较好的药物、无毒
水溶性聚合物和
润湿剂组成。本发明还公开了制备组合物的工艺。含有已知抗真菌药物
鬼臼毒素的组合物说明了本发明。
