Povidone-iodine is a chemical complex of povidone, hydrogen iodide, and elemental iodine. [4] The recommended strength solution contains 10% Povidone, with total iodine species equaling 10,000 ppm or 1% total titratable iodine. [4] It works by releasing iodine which results in the death of a range of microorganisms. [1]
The agent is a polymer with an average molecular weight of 40,000. The povidone iodine contains 10% available iodine, slowly released when applied to skin. This preparation is employed topically as a surgical scrub and non irritating antiseptic solution; its effectiveness is directly attributed to the presence and release of iodine from the ...
Medical iodophor (Chinese povidone-iodine solution) An iodophor is a preparation containing iodine complexed with a solubilizing agent, such as a surfactant or water-soluble polymers such as povidone (forming povidone-iodine), [1] [2] The result is a water-soluble material that releases free iodine when in solution.
Unlike tincture of iodine, Lugol's iodine has a minimised amount of the free iodine (I 2) component. Iodine glycerin, a preparation used in dentistry. Povidone iodine (an iodophor). Iodine-V: iodine (I 2) and fulvic acid form a clathrate compound (iodine molecules are "caged" by fulvic acid in this host-guest complex). A water-soluble, solid ...
Skin disinfection may be accomplished with a number of solutions including providone-iodine, chlorhexidine, alcohol based solutions, and cetrimide. [2] There is strong evidence that chlorhexidine and denatured alcohol use to clean skin prior to surgery is better than any other commercially available antiseptic, such as povidone-iodine with alcohol.
Iodine, especially in the form of povidone-iodine, is widely used because it is well tolerated; does not negatively affect wound healing; leaves a deposit of active iodine, thereby creating the so-called "remnant", or persistent effect; and has wide scope of antimicrobial activity.
Inadine is an iodine-containing non-sticky surgical dressing consisting of a knitted viscose fabric with a polyethylene glycol base that contains and slowly releases the antiseptic povidone-iodine (PVP-1). [1] [2] It is a topical wound dressing and is considered suitable for superficial wounds.
Cadexomer iodine is an iodophor that is produced by the reaction of dextrin with epichlorhydrin coupled with ion-exchange groups and iodine. It is a water-soluble modified starch polymer containing 0.9% iodine, calculated on a weight-weight basis, within a helical matrix.
