Abstract: A composition, or article for inhibition of bone growth and resorption comprises an anti-inflammatory agent(s), optionally other agents and carriers, monomer(s), oligomer(s), polymer(s), salt(s), mixtures(s), dispersion(s) and/or blend(s) thereof, which composition, device, or implant upon polymer erosion releases a bone growth and/or bone resorption retarding, reducing or inhibiting amount of the agent(s). The monomers, oligomers and polymers, releasing active or activatable agent(s), have pre-selected properties such as molecular weight, flexibility, hardness, adhesiveness, and other valuable properties. The monomers, oligomers and polymers may be prepared by a process involving various alternative and sequential steps that allow the design a priori of products with specific characteristics.
