Abstract

A composition of goserelin sustained release microspheres is provided. The microspheres comprise goserelin, at least one poly (lactide-co-glycolide) and poloxamer or PEG. The sustained release microspheres have comparatively high bioavailability, which promotes the drug taking its full effect and have entrapment efficiency over 90%.
