Abstract

An inflammation-relieving filming powder for injury wound contains polyvinyl pyrrolidone iodine (0.5-10 wt. portions) and water-soluble chitosan (10-300 portions). Its advantage is high healing speed.

Description

technical field [0001] The invention relates to the technical field of wound anti-inflammatory film-forming powder composite preparations for trauma. Background technique [0002] At present, the drugs used clinically for anti-inflammation of traumatic wounds all have the problems of being unable to form a protective film on the wound, resulting in poor antibacterial efficacy and slow wound healing. [0003] Clinically, polyvinylpyrrolidone-iodine is a complex of polyvinylpyrrolidone and iodine, and it is a polymer carrier drug. It precipitates iodine in water, or when it comes into contact with the skin or mucous membrane, it can gradually decompose and release slowly. Iodine plays the role of disinfection and killing microorganisms, has high-efficiency and broad-spectrum bactericidal effect, and has strong killing ability and disinfection effect on bacteria, fungi and viruses. [0004] Clinical studies have shown that water-soluble chitosan has a better effect in promotin...
