PVPiodine

PVPiodine is a chemical complex consisting of polyvinylpyrrolidone (PVP) and iodine. It is commonly known as povidone-iodine. The PVP acts as a carrier, gradually releasing elemental iodine. This combination makes it a widely used antiseptic and disinfectant.

The primary mechanism of action of PVPiodine is the release of iodine, which is a potent oxidizing agent. Iodine disrupts essential cellular processes in microorganisms, including proteins and nucleic acids, leading to cell death. It is effective against a broad spectrum of pathogens, including bacteria, viruses, fungi, and protozoa.

PVPiodine is available in various formulations, such as solutions, ointments, and surgical scrubs. It is frequently used in healthcare settings for skin preparation before surgical procedures, wound disinfection, and general antisepsis. Its low incidence of allergic reactions compared to other iodine preparations contributes to its popularity.

The complex is generally considered safe for topical application when used as directed. However, like any antiseptic, it can cause skin irritation in some individuals. Prolonged or extensive use, particularly on large wounds or burned areas, may lead to systemic absorption of iodine, potentially affecting thyroid function, especially in infants and pregnant women. It is important to follow product instructions and consult a healthcare professional if concerns arise.
