Abstract
This invention provides biodegradable, sustained-release pharmaceutical compositions of non-steroidal, anti-inflammatory drugs (NSAIDs) formulated with biocompatible, biodegradable tyrosine-derived polyarylates. The compositions are particularly suitable for localized delivery of NSAIDs for various disease states. For example, implantation of the compositions at the site of surgery leads to relatively high local concentrations of the NSAID to reduce or alleviate post-surgical pain. Long term zero order release of certain NSAIDs can also be provided by with certain polymer formulations.
