Taurolidine

Published: July 26, 2026Updated: July 26, 2026

Taurolidine is an antimicrobial and anti-biofilm agent used primarily as a catheter lock solution to prevent catheter-related bloodstream infections. It works by disrupting bacterial cell membranes and preventing biofilm formation on catheter surfaces, making it particularly valuable for patients requiring long-term central venous access such as those on hemodialysis or receiving chemotherapy.

Quick summary

Taurolidine is an antimicrobial catheter lock agent used to prevent infections in patients requiring long-term central venous catheters.

Common formulation

Value:Catheter lock solution

Taurolidine is primarily formulated as a catheter lock/lock solution

Prevention of catheter-related bloodstream infections (CRBSI) in patients with central venous catheters, particularly for hemodialysis patients, oncology patients, and those requiring long-term parenteral nutrition. Also used as part of antibiotic lock therapy for treating catheter infections.

Taurolidine exerts antimicrobial activity by disrupting bacterial cell wall integrity and interfering with bacterial adhesion to catheter surfaces. It has broad-spectrum activity against gram-positive and gram-negative bacteria as well as fungi. Additionally, it has anticoagulant properties that help prevent catheter thrombosis.

Taurolidine is typically administered as a catheter lock solution (instilled into the catheter lumen) rather than given systemically. It may be combined with heparin in catheter lock solutions for combined antimicrobial and anticoagulant protection. As with all catheter lock therapies, proper administration technique is essential to minimize infection risk.
