Biodegradable Thermosensitive PLGA-PEG-PLGA Polymer

Biodegradable thermosensitive polymer, poly(dl-lactide-co-glycolide-b-ethylene glycol-b-dl-lactide-co-glycolide) (PLGA-PEG-PLGA) is a desirable ophthalmic drug delivery system because it can be formulated into an injectable solution which forms a gel in situ to provide prolonged drug release.
