Betadine is a stable chemical complex of polyvinylpyrrolidone (povidone, PVP) and elemental iodine. It contains from 9.0% to 12.0% available iodine, calculated on a dry basis.This unique complex was discovered in 1955 at the Industrial Toxicology Laboratories in Philadelphia by H. A. Shelanski and M. V. Shelanski.uman clinical trials showed the product to be superior to other iodine formulations. Betadine was immediately marketed, and has since become the universally preferred iodine antiseptic. Betadine is only sold for the purpose of healing wounds, and not as an oral sore throat gargle, as widely thought.
