Povidone iodine displays excellent antibacterial activity which can against MRSA and MSSA strains with MICs of 31.25 mg/L and 7.82 mg/L, respectively.


DryPowder|YELLOW-TO-BROWN HYGROSCOPIC POWDER.


An iodinated polyvinyl polymer used as topical antiseptic in surgery and for skin and mucous membrane infections, also as aerosol. The iodine may be radiolabeled for research purposes.


Povidone iodine is a complex of iodine with povidone. It occurs as a yellowish brown to reddish brown amorphous powder, having a slight characteristic odour. Its solution is acid to litmus. Soluble in water and in alcohol, practically insoluble in chloroform, in carbon tetrachloride, in ether, in solvent hexane, and in acetone. It is an external antiseptic with a broad microbicidal spectrum against bacteria, fungi, viruses, protozoa, and yeasts. This gel has about 1.0% available iodine.


Povidone iodine (PI) is frequently used during surgical preparation, postoperative wound cleaning and dressing. It was described by Shelaski about seventy years ago (Shelanski and Shelanski, 1956). PI consists of the complex structure of povidone, a polymer that is structurally similar to plasma proteins, and the iodine element, which has antimicrobial properties. The function of polyvinylpyrrolidone (PVP) used as a polymer includes increasing iodine solubility and penetration, decreasing iodine ion concentration and keeping iodine bound. However, PVP does not have antimicrobial properties. Shelanski defined this complex structure as 'iodophor' (Shelanski and Shelanski, 1956).

Toxicity

IDENTIFICATION AND USE: 1-Vinyl-2-pyrrolidinone polymers, iodine complex (povidone-iodine) is a yellowish-brown amorphous hygroscopic powder. Povidone-iodine is an iodophore that is used as a disinfectant and antiseptic mainly for the treatment of contaminated wounds and pre-operative preparation of the skin and mucous membranes, as well as for disinfection of equipment. HUMAN EXPOSURE AND TOXICITY: From patch tests carried out in 413 patients with contact dermatoses, 1 was found to be allergic to povidone-iodine. Reversible hyperthyroidism has been reported during the second week of treatment of first- and second-degree burns to the dorsa of both hands with povidone-iodine; delayed iodine excretion might have been involved. In another case report severe hypernatremia and acidosis occurred in a patient with second-degree burns who was treated topically with povidone-iodine. In addition, hypothyroidism in a neonate following topical administration to a surgical wound of a providone-iodine ointment has been described. Burns are a rare but potentially serious complication of povidone-iodine use. Acute renal failure secondary to povidone iodine administration is possible, especially through mucosal surfaces. In addition, even dilute solutions of povidone-iodine are toxic to human fibroblasts. The concentrations used clinically (0.1 to 20%) are toxic for granulocytes and monocytes. Povidone-iodine was cytotoxic to SH-SY5Y (neuronal) and RSC96 (Schwann) cells. ANIMAL STUDIES: Povidone-Iodine preparation was ototoxic in guinea pigs. Corneal edema developed in rabbits when povidone-iodine was placed directly in the anterior eye chamber. Injury to the urothelium occurred from intravesical instillation in female rats. No long-term studies in animals have been performed to evaluate the carcinogenic or mutagenic potential of povidone-iodine. One report of the mutagenic potential of povidone-iodine indicated that it was positive in a modification of the Ames S. typhimurium model, but these results could not be reproduced by another researcher. Another test using mouse lymphoma and Balb/3T3 cells showed that povidone-iodine has no significant mutagenic or transformation capabilities. Other data indicated that it does not produce mutagenic effects in mice or hamsters according to the dominant lethal test, micronucleus test, and chromosome analysis.

The effect of ethyl alcohol, glycerin, sodium lauryl sulfate, benzalkonium chloride (I) and polysorbate 80, on iodine release from povidone-iodine formulations, was studied in vitro and in rats. Ethyl alcohol and I increased the absorption of iodine 24 h after oral doses. In vitro results on iodine release were variable, with I producing the greatest effect. Possible interferences with laboratory tests were noted. Liver, blood and thyroid levels in rats were reported.

An overload of iodine can suppress thyroid hormonogenesis, and the fetal and neonatal thyroid glands are especially sensitive. In pregnant women, vaginitis should not be treated with povidone-iodine because of the possible development of iodine-induced goiter and hypothyroidism in the fetus and newborn. The risk is especially high when povidone-iodine is used repeatedly.|Regular or prolonged use should be avoided in patients with thyroid disorders or those receiving lithium therapy.

According to the 2012 TSCA Inventory Update Reporting data, the number of persons reasonably likely to be exposed in the industrial manufacturing, processing, and use of povidone-iodine is 500-999; the data may be greatly underestimated(1).|NIOSH (NOES Survey 1981-1983) has statistically estimated that 94,521 workers (86,547 of these were female) were potentially exposed to povidone-iodine in the US(1).

Topical application of povidone iodine on the umbilical cord and normal intact skin of newborn infants resulted in significantly elevated plasma iodine levels. High iodine levels were also found in two neonates who had povidone iodine applied to denuded skin. No significant alteration in thyroid function was seen. The possible toxic manifestations of high plasma iodine levels are discussed.|In 12 nonpregnant women, total iodine, protein-bound iodine, inorganic iodine, and thyroxine values were measured in serum before and 15, 30, 45 or 60 minutes after a two-minute vaginal disinfection with povidone-iodine (Betadine). Only 15 minutes after application, serum iodine levels were raised and remained significantly elevated 30, 45 and 60 minutes after disinfection. Serum concentrations of total iodine and inorganic iodine were increased up to fivefold to 15-fold, respectively; during the relative short period of observation, thyroxine levels were not altered.

povidone iodine has bactericidal effect like iodine. It can be used as disinfectant and bacteriostatic agent in the medicine for anti-septic purposes for eye drops, nasal drops, and cream agents. It can also be made into disinfectant. povidone iodine is mainly used for the skin disinfection and equipment disinfection in hospital surgery and injections as well as prevention of infection in the field of stomatology, gynecology, surgery, and dermatology; it can also be used for disinfection of household utensils and appliances; for food industry and aquaculture industry, it is used for disinfection and animal disease control. It is the preferred international and domestic choice of medical iodine-contained fungicides and disinfectants for epidemic prevention. povidone iodine is a kind of iodine carrier, the so-called “tamed iodine”. Because this product can gradually release iodine to exert an antibacterial effect; its mechanism of action is through causing the protein denaturation and further death of bacteria. It is effective in treating bacteria, fungi, as well as viruses with a relative small tissue irritation effect.

Drug Function and Efficacy

Povidone-iodine belongs to the iodine disinfectant class. The 1-vinyl-2-pyrrolidone homopolymer is a surfactant, which helps the solution to wet and penetrate objects, thereby enhancing the bactericidal effect of iodine. It can destroy the permeability barrier of bacterial cell walls, leak nucleic acids, reduce enzyme activity, and kill bacteria. It has a good killing effect on bacterial propagules, fungi, and respiratory and intestinal viruses. Its bactericidal effect is enhanced as the free iodine contained in the solution increases.

This ingredient has been used in drugs with the following functions (note: it does not mean that the ingredient itself has the following health functions)
