Description

technical field [0001] The invention relates to the technical field of medicine preparation, in particular to a film-forming povidone-iodine solution and a preparation method and application thereof. Background technique [0002] Povidone-iodine (PVP-I) is a topical disinfectant and preservative formed by the complexation of iodine and polymer compound povidone (PVP). Povidone-iodine is povidone iodine disinfectant, which is a broad-spectrum powerful bactericidal disinfectant, which has a strong killing effect on viruses, bacteria, fungi and mold spores. PVP is a non-ionic surfactant hydrophilic polymer, which has no antibacterial effect itself, but can improve the solubility of iodine. During the production process, PVP forms a micro-cavity carrier, and complexes iodide ions in the cavity of the microcapsule to form PVP-I. In the aqueous solution state, due to its affinity to the cell membrane, iodine can be directly introduced to the surface of bacterial cells, which is ...
