Development of Novel Adhesive Bilayer Lyophilized Wafer of Moxifloxacin as a Modern Wound Dressing

Wound healing is a complex process and is influenced by different factors. Aimed to enhance the wound healing procedure, the Moxifloxacin bilayer wafer was designed, optimized and evaluated as an advanced wound healing dressing. The wafers were prepared by the lyophilization and casting method. Optimization was done according to the results of bioadhesion force, swelling index, release rate, T40 and T90 (the time to reach 40% and 90% of release). The optimized wafer was evaluated against in-vitro and in-vivo efficacy using the disc diffusion method and histologic evaluation after application on the wound. The optimized formulation contained HPMC, MC, gelatin and PVP with mounts of 50 mg, 25 mg, 2 mg and 10 mg respectively. The hydrophilic bilayer wafer is adhered to the wound up to the end of wound healing. Application of optimized formulation led to the healing of wound 6 days faster without any sign of infection. The application of this wafer promoted wound healing and epithelium regeneration without any inflammation.
