Betadine ointment, povidone iodine  0.1 g / g 30 g (tube)

Indications Betadine ointment, povidone iodine  and action:

Iodized povidone is a complex of iodine and polyvinylpyrrolidone polymer, from which iodine is released for some time after application. Elemental iodine has strong bactericidal properties. In vitro, it quickly kills all bacteria, viruses, fungi and some protozoa. The mechanism of action is as follows: free iodine has a rapid bactericidal effect, while the polymer acts as an iodine store. Upon contact with the skin or mucous membranes, the polymer releases increasing amounts of iodine. Iodine interacts with the oxidizing -SH and -OH groups of amino acids that are part of microbial enzymes and structural proteins, as a result of which the proteins are inactivated or destroyed. In vitro, most microbes die in less than a minute, most in the first 15-30 seconds. In the course of this process, iodine loses its color, and therefore the intensity of the brown color can be treated as an indicator of the effectiveness of the preparation. Loss of color indicates a need for another dose. There are no known cases of resistance.
