Povidone iodine (PVP-I) 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.

Povidone iodine History

Povidone iodine was discovered at the Industrial Toxicology Laboratories in Philadelphia by H. A. Shelanski and M. V. Shelanski. They carried out in vitro tests to demonstrate antibacterial activity, and found that the complex was less toxic than tincture of iodine in mice. Human clinical trials showed the product to be superior to other iodine formulations.
It was first sold in 1955, and has since become the universally preferred iodine disinfectant.

Povidone iodine Uses

Povidone iodine has been broadly used for the prevention and treatment of skin infections, and the treatment of wounds.
Povidone iodine has found broad application in medicine as a surgical scrub; for pre- and post-operative skin cleansing; for the treatment and prevention of infections in wounds, ulcers, cuts and burns; for the treatment of infections in decubitus ulcers and stasis ulcers; in gynecology for vaginitis associated with candidal, trichomonal or mixed infections.

Povidone iodine Specification

Povidone-iodine (PVP-I), brand name Wokadine, Pyodine, and 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. They carried out tests in vitro to demonstrate anti-bacterial activity, and found that the complex was less toxic in mice than tincture of iodine.
Human 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.
It is on the WHO Model List of Essential Medicines, the most important products needed in a basic health system.
