What is Povidone-Iodine?

Povidone-iodine is a complex of free iodine and the synthetic carrier polymer povidone. In an aqueous medium, the povidone complex will release free iodine into the solution to kill germs.


Why we choose povidone-iodine?

Researches had suggested that povidone-iodine has many characteristics that made it highly effective for acute and chronic wound treatment:

  • It reacts in a shorter time and has a broader spectrum of antimicrobial activity. Povidone-iodine is effective against bacteria, several viruses, fungi, spores, protozoa, and amoebic cysts.

  • Lack of resistance: povidone-iodine develops less resistance relative to other antiseptics and antibiotics over 150 years of use.

  • Efficacy against biofilms: Sometimes, biofilms can form on the wound surface, which can delay wound healing and promote bacterial survival in the antimicrobial therapies. Povidone-iodine could sustain its efficiency in the presence of biofilms or inhibited biofilms formation.

  • Good tolerability: Clinical tests showed that povidone-iodine is tested less toxic to cells and induces a less allergic reaction.
