Betadine Dry Powder Spray Mechanism of Action

Pharmacology: Pharmacodynamics: POVIDONE-IODINE (BETADINE) dry powder spray is an organic-solvent formulation, containing povidone-iodine, indicated for treatment and prevention of skin infections in wounds including ulcers, burns, cuts, abrasions and other minor injuries.
It provides an effective barrier to bacteria, viruses, fungi, spores and protozoa allowing wounds to heal without further infection. In addition to its antiseptic properties, the preparation had a tanning effect that prevented early, undesired decomposition of skin that had been burnt. Thus, surgical removal of necrotic tissue could be delayed until the overall condition of the patient was improved. Furthermore, surgical procedures would be facilitated by the clear demarcation of affected tissue from non-affected tissue, resulting from the tanning of the dead layers of skin.
POVIDONE-IODINE (BETADINE) dry powder spray is well tolerated for the skin, mucous membranes and wounds. It is effective against a broad spectrum of human pathogens (e.g. gram-positive and gram-negative bacteria, acid-fast bacteria, spores, fungi, viruses, protozoa and other microorganisms). It has also been proven effective on highly resistant bacteria (e.g. MRSA).
