Abstract
The invention relates to antisepsis and anti-inflammation medicaments, and particularly relates to high-content liquid povidone-iodine. The liquid povidone-iodine is prepared from the following raw materials in percentage by weight: 5.2-12.24 percent of iodine, 10-24 percent of polyvinylpyrrolidone, 2-4.8 percent of potassium iodide, 0.1-0.24 percent of potassium iodate, 15-36 percent of ethanol and the balance of water. The high-content liquid povidone-iodine is a reddish brown viscous liquid, is easily dissolved in water, has stable performance, strong sterilization efficacy and no irritation, is suitable for sterilization of operating parts and skin-mucosa or sterilization of aquatic water, can be used for preventing and treating bacteriosis of aquatic animals caused by vibrio, aeromonas hydrophila, edwardsiella tarda and the like and sterilizing the environment of livestock and poultry housings, plays a role in killing multiple bacteria, spores, viruses, fungi and the like, thus being a good iodine containing medical bactericide and epidemic prevention sanitizer.
Description
technical field [0001] The invention relates to an antibacterial and anti-inflammatory drug, in particular to a high-content liquid povidone-iodine. Background technique [0002] Povidone-iodine (PVP-I) is an iodine-containing disinfectant. It releases free iodine, destroys the metabolism of bacteria, inactivates bacteria and other microorganisms, and has a good killing effect on bacteria, viruses and fungi. It is often used for disinfection of surgical sites and skin and mucous membranes; it can also be used for disinfection of aquaculture water to prevent bacterial diseases caused by Vibrio, Aeromonas hydrophila, Edwardsiella, etc. in aquaculture animals; it is also used for livestock and poultry houses Environmental disinfection. [0003] Povidone-iodine currently on the market, the available iodine content of 9% to 12% is yellowish brown to reddish brown amorphous powder, in actual use, it is generally diluted until the available iodine is between 0.5% and 2%, and the p...
