Geistlich TauroSept®

Prevention and treatment of CVAD infections through broad anti-microbial activity

Geistlich TauroSept® contains the antimicrobial chemotherapeutic agent taurolidine 2 %. Unlike antibiotics, taurolidine acts via a chemical reaction with the microbial cell wall. Microbes are killed and resulting toxins are inactivated; the destruction time in vitro is 15–30 minutes. Taurolidine has an extremely broad antimicrobial and antimycotic spectrum, which also includes methicillin- and vancomycin-resistant bacteria (MRSA, VISA and VRE). (1, 2, 3, 4) Preventive instillation of Geistlich TauroSept® helps to avoid impending CVAD colonisation. (5, 6, 7, 8) When CVAD colonisation already exists the microbial contamination can be eliminated by the therapeutic use of Geistlich TauroSept® in combination with systemic antibiotics. In many cases the removal of the CVAD can be avoided or delayed for a long time. (9, 10)


Reliability in long-term use due to the absence of development of microbial resistance

In many years of clinical use development of microbial resistance due to taurolidine has never been observed. Because of the special mechanism of action of taurolidine, in which a reaction with the microbial cell wall occurs directly, development of resistance is unlikely and not to be expected in contrast to antibiotics. (11, 12)


Interference with biofilm development through inhibition of microbial colonisation

Even at low concentrations, taurolidine causes a loss of microbial fimbriae and flagellae. Due to the change in the microbial surfaces, the capacity to form colonies is lost and the adhesion of microbes to the surfaces of epithelia and biomaterials is prevented. These antiadhesive properties of taurolidine counteract the biofilm formation. (13, 14)


Promotion of intraluminal haemodynamics by reducing local pathological coagulation phenomena

Depending on duration of exposure and concentration, taurolidine causes inhibition of staphylocoagulase-mediated coagulation, which cannot be influenced by heparin. The risk of pathological staphyloco-agulase-induced coagulation occurring especially at the CVAD tip is therefore reduced. (15)


Safety in use due to outstanding systemic tolerability

Taurolidine is also licensed as an active pharmaceutical ingredient for the local treatment of infections such as peritonitis; up to 200 ml of taurolidine 2 % are instilled daily into the abdominal cavity and absorbed fully through the peritoneum. So far, no systemic side effects have been identified. The safety of taurolidine has also been confirmed in clinical studies with long-term intravenous administration of high doses (up to 20 g daily).16 In the body, taurolidine is metabolised rapidly via the metabolites taurultam and methylol taurinamide, which also have an anti-microbial action, to taurine, an endogenous aminosulphonic acid, CO2 and H2O. Therefore, no toxic effects are known or expected in the event of accidental injection.17
