With the background of snowballing threat of skin wound to public health and economy, this study was undertaken utilizing xanthan gum (Xnt), citric acid (C), gelatin (Gel), glutaraldehyde (G) and HPLC-grade water to fabricate a series of composite hydrogels i.e. Xnt, Xnt:C, Xnt:Gel(3):G, Xnt:C:Gel(3):G, Xnt:Gel(5):G, Xnt:C:Gel(5):G for investigating their wound healing efficacy in experimental rat skin wound model. Physicochemical characterization revealed that all the composite hydrogels contained more than 90% water. The hydrogels displayed swelling ability, biodegradability, good polymeric networks and porosity. Fourier Transform Infrared Spectroscopy (FT-IR) studies confirmed the presence of bound water and free, intra and inter molecular bound hydrogen bonded OH and NH in the hydrogels. All the hydrogels showed significant wound healing potency in experimental deep second degree skin burns in rats compared to controls. 20 days post-application of hydrogels, Xnt:Gel(3):G, Xnt:Gel(5):G and Xnt:C:Gel(5):G-treated wounds showed better recovery compared to other composite hydrogels. We conclude that, Xnt:Gel(3):G, Xnt:Gel(5):G and Xnt:C:Gel(5):G might be effective wound dressing material.
