Wound Healing –A Review of Novel Therapeutic Strategies

Abstract

New ideas on controlling the pharmacokinetics, pharmacodynamics, nonspecific toxicity, immunogenicity and efficiency of drugs have generated new strategies, often called as the drug delivery system. Development of an existing drug molecule can significantly improve its performance in terms of patient compliance, safety, and efficacy from a conventional form to a novel delivery system can significantly improve . The variety of dressings based on types of wounds and novel polymers used for the delivery of drugs to acute and chronic wound has resulted in a wide range of new products frequently introduced to target different aspects of the wound healing process. These include hydrocolloids, alginates, hydrogels, polyurethane, collagen, chitosan, pectin and hyaluronic acid. Nevertheless, nanofibers with their physicochemical properties and nanotopography display improvements in the fields of tissue engineering, wound therapy and drug delivery systems. At present, there are so many existing drug delivery technologies that a total compilation is not within the scope of this article. Yet an attempt is being made to compile some of the most successfully marketed drug delivery technologies. This review extends the information and hopes to give insight into past, present and future strategies and approaches for wound healing managements.
