  • Povidone-Iodine is the active ingredient in Betadine, and it is a complex of iodine and PVP. It is also known as an iodophor, a substance that acts as a reservoir of 'free' active iodine. Povidone-iodine is available in different formulations, such as aqueous solutions, alcoholic solutions, and surgical scrubs.
