Mechanism of action:

PVP-I functions as an antiseptic through several mechanisms and is considered to have the broadest spectrum of action compared to other common antiseptics such as chlorhexidine. The two most potent antiseptic metabolites of PVP-I are molecular I2 and hypoiodous acid, which deliver free iodine. These free iodine molecules oxidize amino acids, nucleic acids and cell membranes. Through oxidation of cell surface receptors, PVP-I prevents the attachment of viruses to cellular receptors.
