Abstract

A biodegradable, injectable oligomer-polymer composition is described, which consists of a combination of at least two biologically degradable inert materials and at least one biologically active ingredient. The inventive, oligomer-polymer composition coagulates when injected into the body of a mammal and forms an implant, from which the biologically active ingredient is released. The rate of release can be adjusted by controlling the type and amount of the ingredients of the oligomer-polymer composition.
