Sustained release biodegradable or bioerodible microspheres or microparticles suspended in a solid depot-forming injectable drug formulation

摘要

Complex drug delivery materials can be injected into the human or mammalian eye to provide sustained delivery of the drug. The composite drug delivery material can include a plurality of microparticles dispersed in a vehicle composition. The microparticles can include a drug and a coating comprising a bioerodible material or a biodegradable material, and the media composition includes the drug dispersed in the depot-forming material. The media composition can be gelled or solidified upon injection into the eye. [Selection figure] None
