摘要:
The present invention relates to microparticles comprising a gel body, wherein the gel body comprises a synthetic polymer and a drug, wherein the microparticles have an average diameter in the range 40 to 1500 mum, wherein the polymer is cross-linked by groups comprising disulfide linkages and is in the form of a hydrogel.
摘要:
Biodegradable and bioabsorbable block copolymers, which can be in the form of solid powder or powder wax compositions that can be easily reconstituted into an aqueous polymer solution and exhibit reverse thermal gellation properties upon exposure to elevated temperatures, are provided. Methods of making using these copolymers are also provided.
