Toraymyxin® – Polymyxin B hemoperfusion therapy – (Toray Industries Ltd., Japan) is the state-of-the-art therapy for the treatment of patients with endotoxic septic shock who are unresponsive to conventional treatment. More than 200,000 patients have been treated with this innovative therapy and more than 400 peer-reviewed articles have been published demonstrating the safety and effectiveness of Polymyxin B hemoperfusion therapy.
Polymyxin B hemoperfusion therapy takes advantage of the strong endotoxin neutralizing capability of Polymyxin B intelligently immobilized to polystyrene fibers. The innovation by TORAY enabling Polymyxin B (polycationic antibiotic) therapy by means of extracorporeal hemoperfusion has provided the most effective therapy for the neutralization of endotoxin, a pathogenic substance, and potent killer, when present in the bloodstream.
Toraymyxin® is the reference therapy for the treatment of patients with endotoxic septic shock who are unresponsive to conventional therapies. With its outstanding endotoxin removal capacity, high-affinity binding may remove up to 90% of circulating endotoxin after two hemoperfusion treatments. Since its introduction, more than 200,000 patients have been treated with polymyxin B hemoperfusion (PMX-HP), with a low incidence of reported adverse events (<1%), and high tolerability. More than 400 peer-reviewed articles have been published and numerous clinical studies have demonstrated the positive effect of PMX-HP therapy on hemodynamics, organ function, and survival in patients with septic shock.
Although PMX-HP therapy was designed to adsorb endotoxin, other mechanisms of immunomodulation have been demonstrated. Some of these mechanisms are caused by the elimination of endotoxin, while others result from the direct adsorption of inflammatory mediators, such as activated immune cells and the inactivation of circulating renal apoptotic factors. PMX-HP is currently the only therapy available to effectively neutralize endotoxin, immune cells, and inflammatory mediators in patients with septic shock.
Toraymyxin® is now available in two versions:
- PMX-20R device: for patients with adult body volume
- PMX-05R device: for patients with reduced volume
Both devices contain 5 mg of Polymyxin B per each gram of matrix fiber ensuring maximum action of Polymyxin B in hemoperfusion modality.
PMX-05R is the first blood purification device conceived as a complementary therapy in patients with a reduced volume affected by endotoxic septic shock, fully conformant with the standards of TORAY.
