The invention relates to liquid pharmaceutical formulations for oral administration with the modified release of active principle(s), excluding amoxicillin, said formulations consisting of suspensions of coated particles of active principles (microcapsules). According to the invention, the microcapsules constituting the disperse phase of the suspension are designed to allow the modified release of the active principle(s) according to a profile that does not change during the storage of the liquid suspension. To do this the inventors propose the selection of a specific coating composition for the microcapsules which consists of at least four components that allow these microcapsules to be stored in water without modifying their properties of modified release of the active principle, this liquid phase furthermore being saturated with active principle(s).
本发明涉及活性成分(不包括
阿莫西林)改变释放的口服液体药物制剂,所述制剂由活性成分包衣颗粒(微胶囊)悬浮液组成。根据本发明,构成悬浮液分散相的微胶囊的设计目的是使活性成分的释放曲线在液体悬浮液的储存过程中不会发生变化。为此,发明者建议为微胶囊选择一种特定的涂层组合物,该组合物至少由四种成分组成,可使这些微胶囊在
水中储存而不改变其活性成分的改良释放特性,而且这种液相还饱含活性成分。
