The present invention is directed towards articles comprising a steroid material comprising a steroid dimer and at least one therapeutic agent distributed throughout the steroid material and the use of such articles in sustained release delivery systems. Said article may be fibers, fiber meshes, woven fabrics, non-woven fabrics, films, pellets, cylinders, microparticles, nanoparticles, shaped articles or coatings on a substrate (such as an implant). Control of the release profile of the at least one therapeutic agent can be achieved via selection of the steroids within the steroid dimer, the linker conjugating the steroids within the dimer, the linkage groups between the steroids and the linker, the surface area of the article, the location of the at least one therapeutic agent within the article and the amount of the at least one therapeutic agent within the article.
