    • The present invention relates to a composition for the controlled-release of drugs. More particularly, the composition for the controlled-release of drugs according to the present invention expands the capacity for the controlled-release of a matrix-type polymer for controlled-release via a carbomer in which said polymer for controlled-release forms a basic frame and in which sol-gel transition occurs in accordance with a pH level. The composition of the present invention is characterized in that it comprises: a solubilizing agent for the event the drug to be released is highly insoluble, and a disintegrating agent for sufficient initial release. The composition for the controlled-release of drugs according to the present invention uses a carbomer which maintains the controlled-release of conventional matrix structures having polymers for controlled-release and which has sol-gel transition properties, thus preventing a sudden release of a drug caused by a collapse of the matrix structure during a late stage of elution. In addition, the composition of the present invention uses a solubilizing agent to solve the problem of a highly insoluble drug failing to dissolve even after being released, and also uses a disintegrating agent to improve the speed of the initial release, which is the limiting factor in controlled-release preparations.
    • 本发明涉及用于药物控制释放的组合物。 更具体地说,根据本发明的用于药物控制释放的组合物通过卡波姆扩大了用于控制释放的基质型聚合物的释放能力,其中所述控释聚合物形成基本框架 并且其中根据pH水平发生溶胶 - 凝胶转变。 本发明的组合物的特征在于,它包括:用于释放药物高度不溶性的增溶剂,以及用于充分初始释放的崩解剂。 根据本发明的用于药物控制的组合物使用卡波姆,其维持具有用于控制释放的聚合物的常规基质结构的控制释放,并且具有溶胶 - 凝胶转变特性,从而防止药物的突然释放 由洗脱后期的基体结构的崩溃引起的。 此外,本发明的组合物使用增溶剂来解决即使在剥离后不能溶解的高度不溶性药物的问题,并且还使用崩解剂来提高初始释放的速度,这是限制因素 在控释制剂中。
