Description of Povidone iodine:
PVP-I is a complex of PVP with iodine. It exists as a brownish-red powder. Povidone iodine has very low toxicity but is highly effective. PVP Iodine can effectively kill some bacterial, viral, fungal, mold and sporules. Povidone Iodine is a stable complex without irritation. PVP Iodine is completely soluble in water, making it very easy to use.
Popular also known as iodopovidone, povidone iodine is used as an antiseptic that is widely used topically on the skin as a disinfectant before and after surgery. Povidone iodine is used as an antiseptic on the skin of patients and also to disinfect the hands of doctors. It is also important to use to treat minor cuts and wounds. Povidone iodine will be obtained in both powder and liquid form, Povidone iodine powder and Povidone iodide solutions. It is included in the WHO list of essential medicines as one of the safest and most effective medicines.
Povidone iodine, PVP-I, is also used as first aid for minor wounds, abrasions, cuts, blisters, abrasions, and burns. Iodopovidone has the ability to be slowly absorbed through soft tissue. Therefore, Povidone iodide is preferred over other disinfectants in longer surgeries. It is also effectively used in the treatment of ulcers and vaginitis.
Povidone iodine 2.5% buffer solution can be used to prevent neonatal conjunctivitis. Moreover, Povidone Iodine also works in pleurodesis.
Special Notes: Povidone iodine may cause skin irritation. It may also cause high sodium levels in the blood and kidney problems when used on large wounds. The above is considered a side effect of Povidone Iodine.
Povidone Iodine Benefits:
Like PVP K30, Povidone Iodine is a broad-spectrum germicidal agent. Povidone Iodine is widely used to clean skin and equipment before injection or surgery. Anti-infective treatment is another area of application of Povidone iodine.

What is povidone-iodine and why is it popular in Europe?
Povidone iodine is a new generation antiseptic, which in Europe is confidently replacing regular iodine. The reason for its popularity is a more pronounced effect and no burning sensation when used. How is povidone iodine different from regular iodine?
Chemical formula of povidone-iodine (Povidone-iodine)
The main difference is that in the new product, iodine atoms are sorbed on a base of large-molecular polyvinyl alcohol - polyvinylpyrrolidone.
This gives:
· absence of irritating and toxic effect: burning sensation, as when using ordinary iodine, simply does not occur;
· elimination of resorptive toxic effects;
· complete preservation of antiseptic properties;
· effectiveness against fungi, bacteria and viruses;
· the skin “breathes”;
· no feeling of fatness;
· the effect is longer than when using a solution of inorganic iodine.
Doctors call this drug unique because it is as effective as iodine, but does not cause discomfort. This makes it easy to use the product to treat open wounds in young children, obtaining a much stronger effect than when using the usual brilliant green and iodine.
This drug is recommended for use in case of damage to the skin - burn, cut, abrasion, bruise, open wound. It is indicated for the presence of bedsores and the appearance of ulcers in patients with diabetes mellitus and poiderma.
Povidone-iodine is available in the form of a solution with 10 or 7.5 percent iodine, as vaginal suppositories and ointments. A concentrate is also produced, on the basis of which a solution is prepared.
The solution is used by dentists, surgeons, and traumatologists in the prevention and treatment of wound infections. It is used to disinfect the skin and mucous membranes before operations. Surgeons and operating room nurses treat their hands with a 7.5% solution, and also carry out hygienic treatment of patients. The solution is used to treat the throat and oral cavity.
Suppositories are used to treat various gynecological diseases, including fungal and sexually transmitted infections.
Povidone iodine should not be used in case of hypersensitivity to the components of the drug, hyperthyroidism and Dühring's dermatitis, during pregnancy and breastfeeding.
The drug is not compatible with other antiseptics and disinfectants, especially if they contain mercury, alkali, or enzymes.
You can apply the drug to the affected area up to three times a day. The 10% solution is not diluted; it is applied to the skin and mucous membranes. Suppositories are used intravaginally after hygienic procedures. Dosage and frequency depend on the disease for which treatment is prescribed.
If the product is used for more than seven to ten days, iodism may occur, which is expressed in the appearance of a metallic taste in the mouth, increased salivation and the development of swelling of the eyes and larynx.
Lekker Povidone-iodine. The product does not contain alcohol, which causes burning. The solution is released in a convenient form, with a soft brush, which allows you not to stain unnecessary areas of skin or clothing, and to apply the solution pointwise.
