Abstract

The present invention describes an improved method for the preparation of cadexomer iodine. Cadexomer iodine is a hydrophilic modified starch polymer containing 0.9%w/w iodine within the helical matrix. It is used for its absorbent and antiseptic properties in the management of chronic wounds such as venous leg ulcers, pressure sores, etc. It is applied as a powder or as an ointment over the wound.
