In vitro and In vivo characterization of quercetin loaded multiphase hydrogel for wound healing application

Abstract

The present work aim to prepare and evaluate multiphase hydrogel system incorporated with quercetin loaded liposomes (QLH), for wound healing. The quercetin loaded liposomal hydrogel were prepared by taking 15% carbopol and varying gelatin ratio. The clear and transparent hydrogel was obtained by taking ratio of gelatin to carbapol (6/4) compared to other ratios. The best prepared hydrogel were characterized for surface morphology, water vapor transmission rate (WVTR), swelling ratio, hemocompatibility, stability, in-vitro release and in-vivo studies. The evaluated results of (QLH) for surface morphology, WVTR, swelling ratio, hemocompatibility and in-vitro release were found to be significant compared to other prepared formulations. Consequently, on basis of optimized hydrogel was selected to study wound healing activity in albino rats. The results demonstrated accelerated wound-healing with significant decrease in wound closure time compared to conventional dosage form. The results of in-vitro and in-vivo promises reliable mode of treatment for connective tissue disorder as wound healing.
