The present invention provides compositions and methods for the controlled release delivery of one or more biologically active compounds to a subject. Specifically, the invention provides for a pharmaceutical composition for the controlled release delivery of biologically active compounds to a subject comprising: a) a complex of a biologically active compound having at least one basic functional group and a polyanion derived from hexahydroxycyclohexane having at least two negatively charged functional groups; and b) a pharmaceutically acceptable carrier comprising a biodegradable, water-insoluble polymer. By complexing a biologically active compound with a polyanion, the tight, stable complex may be incorporated into a long-acting dosage system having a more desired drug release curve over time than that is found in the prior art. The invention also provides the methods of making such compositions and the methods of use thereof.
本发明提供了一种控制释放给予受体体内一个或多个生物活性化合物的组合物和方法。具体而言,本发明提供了一种制药组合物,用于控制释放生物活性化合物给予受体,包括:a) 生物活性化合物的复合物,其至少具有一个碱性功能团,并且是由至少具有两个负电荷功能团的六羟基环己烷衍生的聚阴离子; 和 b) 包含可生物降解的、水不溶性聚合物的药用载体。通过将生物活性化合物与聚阴离子形成复合物,可以将紧密、稳定的复合物纳入长效剂量系统中,其具有比现有技术更理想的药物释放曲线。本发明还提供了制备这种组合物的方法和使用这种组合物的方法。
