Povidonecontaining

Povidone-containing refers to products that include povidone, typically polyvinylpyrrolidone (PVP), a synthetic water-soluble polymer. PVP is manufactured in grades with different molecular weights and is widely used as an excipient or functional ingredient in pharmaceuticals, cosmetics, and consumer products. As an excipient, povidone acts as a binder, thickener, stabilizer, film-forming agent, and adhesive, helping to improve tablet cohesion, viscosity, and texture.

Povidone-containing formulations in medicine include tablets and capsules where PVP binds active ingredients, liquid suspensions where it stabilizes suspensions, and solutions where it helps solubilize poorly soluble drugs. PVP is also used in topical products and ophthalmic suspensions for its film-forming and moisturizing properties.

A notable subset is povidone-iodine (PVP-I), formed when iodine is complexed with povidone. PVP-I is a broad-spectrum antiseptic used for preoperative skin preparation, wound cleansing, and mucosal disinfection. It releases active iodine slowly, but iodine exposure may be a concern for people with thyroid disease or iodine sensitivity.

Safety and regulation: Povidone-containing products are generally regarded as safe when used as directed, but adverse reactions can include contact dermatitis or irritations. Allergies to povidone and iodine are possible. Regulatory labeling varies by country; products containing PVP or PVP-I are typically subject to pharmaceutical or medical device regulations and must follow local guidelines for antiseptics and excipients.
