US 2014/0235727 A1 · ANTIMICROBIAL HYDROGEL POLYMERS

Abstract

The present invention relates generally to antimicrobial hydrogel polymers, and dressings comprising one or more hydrogel-forming hydrophilic polymers, where the hydrogels and dressings further comprise one or more antimicrobial agents that are released from the hydrogel in a controlled manner. The hydrogels and dressings may be used for medical, veterinary, and/or cosmetic applications. The dressings may be applied, for example, as wound dressings, surgical dressings, and percutaneous site dressings. In certain aspects of the invention, the dressings may be beneficially used in methods of accelerating wound healing, preventing and/or reducing the incidence of wound infection, and reducing scarring associated with wounds.
