Povidone Iodine

Anti septics (local)

Description

It is used on the skin to decrease risk of infection. This medicine is also used as a surgical hand scrub and to wash the skin and surface of the eye before surgery to help prevent infections.

Mechanism of action

Elemental iodine has a very broad antimicrobial spectrum: bacteria, viruses, bacterial endospores, fungi and protozoas are destroyed through oxidative interaction and direct iodination of biological macromolecules. It is a labile complex of iodine with the polyvinyl pyrrolidone polymer, from which iodine is continually delivered. Only this free iodine has antimicrobial activity.
