Patent ID: 8912164

Claim:
A pharmaceutical re-epithelializing composition consisting of: 0.15 weight % hyaluronic acid sodium salt as active principle, 1.0 weight % xanthan gum as active principle, 0.35 weight % sodium chloride as isotonic agent, 0.15 weight % potassium chloride as isotonic agent, 0.012 weight % magnesium chloride.6H 2 O as isotonic agent, 0.0084 weight % calcium chloride.2H 2 O as isotonic agent, 0.089 weight % sodium phosphate dibasic.12H 2 O as buffer, 0.0069 weight % sodium phosphate monobasic.H 2 O as buffer, 0.059 weight % sodium citrate.2H 2 O as buffer and antioxidant, 1.0 weight % glycerol as isotonic agent, and purified water as solvent, wherein the composition is effective for re-epithelialization when applied to epithelium; and the xanthan gum and isotonic agent provide recovery of the structure and viscosity of the composition between blinks resulting in increased time of corneal contact.
