Povidone iodine loaded film-forming topical gel and evaluation of its chemical stability

Abstract

The main aim of this study was to develop Povidone Iodine loaded film-forming gel for excellent wound healing property with various formulations, and corresponding application stratification was prepared with Povidone Iodine, polyethylene glycol-400, polyethylene glycol-4000, aloe vera, and honey. Povidone Iodine is a broad-spectrum antiseptic for topical application in the treatment and prevention of infection in wounds. Among the antiseptic and antimicrobial substances, Povidone-Iodine still occupies its position of lasting importance in everyday human and veterinary medicine. Povidone-iodine products display the broadest spectrum of antimicrobial effect with high clinical efficacy together with extremely low toxicity in clinical practice. The purpose served by dressing includes protecting wounds, promoting healing, and providing, retaining, or removing moisture. Wound repairing is a complex process involving an integrated response by many different cell types and growth factors to achieve rapid restoration of skin integrity and protective function after injury. In recent years, there have been tremendous advances in the design and composition of bandages and dressings, and there are numerous wound care materials. The film-forming optimized gel formulation composed of povidone-iodine, polyethylene glycol-400, polyethylene glycol-4000, aloe vera, and honey and this composition provides suitable consistency, spread ability, and adhesiveness. The prepared trials were coded PGAH-01, PGAH-02, PGAH-03, PGAH-04, and PGAH-05, respectively. Among these all formulations, the PGAH-04 formulation parameters were found within the limit.
