<p>Povidone Iodine is a complex of iodine and an organic polymer, povidone. This polymerization makes Povidone Iodine superior to ordinary elemental iodine. It prolongs the germicidal activity of iodine by liberating elemental iodine slowly. Consequently it has a lower toxicity than elemental iodine. It gives rapid microbicidal activity against both Gram-positive and Gram-negative bacteria, protozoa, viruses and fungi/yeasts. It is also sporicidal. It is the only microbicide with this broad spectrum of activity. It is non-staining, exerts prolong germicidal action and is also active in the presence of soap, blood, serum, pus, mucosal secretions and water.</p>
