Polyethylene glycol hydrogel injection |
| abstract |
TECHNICAL FIELD The present invention relates to a poly (ethylene glycol) hydrogel injecting agent, and more particularly, to a buffer solution (first buffer solution) having a pH of 3.5 to 6 containing a polyethylene glycol derivative having an electrophilic reactive group; And a polyethylene glycol derivative having a nucleophilic reactor and a buffer solution (second buffer) having a pH of 7.5 to 11 containing hyaluronic acid are separately formed to improve the symptoms of arthritic diseases. The injectable preparation of the present invention is excellent in biocompatibility and can be administered for a long time in the joints to exhibit analgesic effect, cartilage protection and inflammation-inhibiting effect, thus preventing or treating effective arthritis. |
