Used primarily as an antimicrobial agent, especially in the prevention and treatment of catheter-related infections. It is commonly applied in solutions for catheter lock therapy to prevent biofilm formation in central venous catheters. Effective against a broad spectrum of pathogens including bacteria, fungi, and endotoxins, it is utilized in clinical settings for patients undergoing hemodialysis or long-term intravenous therapy. Also investigated for use in surgical irrigation to reduce the risk of peritonitis and other postoperative infections. Its mechanism involves irreversible binding to microbial cell walls, leading to cell death without promoting resistance.
