Patent number: 7964219Abstract: 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.
