povidonijodi

Povidone-iodine, also known as pvp-iodine, is a complex of iodine with povidone. It is a chemical compound that has been widely used as an antiseptic and disinfectant. When applied to skin or mucous membranes, it slowly releases iodine, which is responsible for its antimicrobial properties. Iodine works by oxidizing essential components of microbial cells, such as enzymes and structural proteins, leading to cell death.

Povidone-iodine is a brown, amorphous solid or powder that is soluble in water and alcohol. It is often formulated into various preparations, including solutions, ointments, swabs, and scrubs, for topical application. Its broad spectrum of activity includes effectiveness against bacteria, viruses, fungi, and protozoa. This makes it a versatile agent for wound care, surgical preparation, and general disinfection.

Compared to elemental iodine, povidone-iodine has several advantages. It is less irritating to tissues and causes less staining. The povidone polymer also helps to stabilize the iodine and prolong its release, making it a more sustained antiseptic. However, it can still cause allergic reactions in some individuals, and its use may be contraindicated in certain conditions, such as thyroid disorders or during pregnancy. It is important to follow product instructions and consult with a healthcare professional for appropriate use.
