Description of Povidone Iodine

  • 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.

What is Povidone Iodine?

  •      With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Povidone Iodine which has developed particularly rapidly in recent years. Do you know about Povidone Iodine?
  • The official answer: Povidone iodine is an unstable complex of surfactant and iodine, which is a topical disinfectant of the iodoform type. It is a yellowish brown to reddish brown amorphous powder at room temperature, soluble in water or ethanol, insoluble in ether or chloroform. The 1-vinyl-2-arsenyl ketone homopolymer is a surfactant and Chemicalbook contributes to the wetting and penetration of the solution, thus enhancing the bactericidal effect of iodine. It has a high concentration, strong bactericidal power, is tasteless, non-irritating, non-allergenic and has low toxicity. It is a broad-spectrum fungicide, capable of killing viruses, bacteria, budding spores, fungi and protozoa.
  • Povidone iodine is a loose complex combining elemental iodine and a polymeric carrier, with the povidone acting as a carrier and solubility aid. It is a yellowish brown to brownish red amorphous powder at room temperature. It is slightly odorous, soluble in water or ethanol, acidic in aqueous Chemicalbook, insoluble in ether, chloroform, acetone, ethane and carbon tetrachloride. Povidone iodine aqueous solution has no disadvantages of tincture of iodine, shallow colouring, easy to elute, little irritation to mucous membrane, no need for ethanol deiodination, no corrosive effect and low toxicity.

What’s the application of Povidone Iodine?

The main indications for povidone iodine are as follows: 1. For septic dermatitis, skin fungal infections, small mild burns, also for disinfection of small skin and mucosal wounds. 2. For bacterial and mycotic vaginitis, cervical erosion, trichomonas vaginitis, pubic itching, pubic infections with odour, yellowish smelly leucorrhoea, comprehensive pubic Chemicalbook inflammation, senile vaginitis, herpes, gonorrhoea, syphilis and condyloma acuminatum prevention and local treatment disinfection.3. Glansitis, prepuce, external genitalia and surrounding Prevention and local treatment of gonorrhoea, syphilis, and warts.4. Disinfection of tableware and utensils.5. Disinfection of skin at surgical sites.6.
