Patent ID: 11793762

Abstract:
The invention disclosed herein relates to a composition and method of reducing the joint pain associated with hemarthrosis or hemophilic arthropathy. The method includes administering a COX-2 inhibitor, such as rofecoxib, celecoxib, valdecoxib, etoricoxib or other “coxib” drug which is encapsulated in PLGA micro-particles. The COX-2 inhibitor can be administered directly to an area where pain exists by an injection device. In a preferred embodiment, rofecoxib or celecoxib can be encapsulated in PLGA micro-particles for controlled, sustained release over a 2-8-week period. The non-systemic delivery and the controlled, sustained release of rofecoxib alleviate the cardiovascular side effects associated with systemic rofecoxib treatments.
