Anti-adhesion polymer composition capable of supporting growth factor
The present invention relates to an anti-adhesion polymer composition capable of supporting growth factor, which effectively exhibits anti-adhesion function and, at the same time, has an excellent adhesive property so as to be able to easily and continuously adhere to a wound site, has antibacterial and hemostatic properties, and is composed of an injectable formulation suitable for use in minimally invasive surgery, laparoscopic surgery or the like. The anti-adhesion polymer composition capable of supporting growth factor comprises: 24-50 wt % of a polyethyleneglycol-polypropyleneglycol-polyethyleneglycol (PEG-PPG-PEG) block copolymer having a polyethyleneglycol (PEG) content of 65-85 wt % and a molecular weight of 6,000-20,000 Da; 0.03-5 wt % of gelatin; 0.03-5 wt % of chitosan; and distilled water.
1. An anti-adhesion polymer composition consisting essentially of: 24-50wt % of a polyethyleneglycol-polypropyleneglycol-polyethyleneglycol (PEG-PPG-PEG) block copolymer having a polyethyleneglycol (PEG) content of 65-85wt % and a molecular weight of 6,000-20,000Da; 0.03-5wt % of gelatin; 0.03-5wt % of chitosan; distilled water; glycerol as a stabilizer for suppressing phase separation of the composition; and at least one growth factor selected from the group consisting of epidermal growth factor (EGF, beta-urogastrone), heparin-binding EGF-like growth factor (HB-EGF), transforming growth factor-α (TGF-α) and fibroblast growth factors (FGFs).
2. The anti-adhesion polymer composition of claim 1 , wherein the block copolymer is composed of two kinds of block copolymers having different weight % of PEG.
3. The anti-adhesion polymer composition of claim 2 , wherein the amount of each of the block copolymers in the composition is 12-25wt %.
4. The anti-adhesion polymer composition of claim 1 , wherein said composition forms an injectable solution which is capable of adhering to a wound site.
