Abstract

A medicine "Sulfapyrimidine silver-crustamine" in the dosage form of powder contains sulfapyrimidine silver (0.5-2 wt. portions), crustamine (1-50) and polyvinyl alcohol (50-150). Its advantages are high stability and antibacterial effect, and high wound-healing speed.

Description

technical field [0001] The invention relates to the technical field of sulfadiazine-silver-chitosan composite medicine for external use. Background technique [0002] The raw material of sulfadiazine silver is white or off-white crystalline powder, which is easy to deteriorate when exposed to light or heat, and is insoluble in water, ethanol, chloroform or ether. Clinically, powder or ointment (cream) is often used as a treatment for burn wounds. It can not only inhibit wound infection, but also promote wound dryness, scab and healing, and has a significant curative effect. Silver sulfadiazine has a wide antibacterial spectrum, especially strong inhibitory effect on Pseudomonas aeruginosa, and has astringent effect. It is suitable for second or third degrees Burns are common in clinical applications. However, it has the disadvantages of poor stability and antibacterial efficacy, and slow wound healing. [0003] Clinical studies have shown that chitosan has a better effect...
