Polymyxin B

perfusion of venous blood through a cartridge on whose fibers polymyxin B is covalently fixed; in this way the antibiotic exerts its bactericidal function but is not released into the blood since it remains fully attached to the fiber. Through this perfusion the cartridge retains the endotoxin, recognized as the trigger of septic shock. The treatment of the cartridge to polymyxin B (Toraymyxin, medical device designed and produced by the Japanese Toray), takes place in two sessions of two hours each, carried out at a distance of 24 hours.

Removal of the hydrophobic tail of polymyxin B yields polymyxin nonapeptide (PMBN), which still binds to LPS, but no longer kills the bacterial cell. However, it still detectably increases the permeability of the bacterial cell wall to other antibiotics, indicating that it still causes some degree of

Polymyxin B is composed of polymyxins B1, B1-I, B2, B3, and B6. Polymyxins B1 and B2 are considered major components. These related components are structurally identical with the exception of a variable fatty acid group on each fraction. Results from in vitro studies have shown marginal differences

An effective use of polymyxin B is found in patients with refractory septic shock, that is, without positive outcome to the administration of standard treatments (increase in volemia and other antibiotics). The obstacle of the toxicity of polymyxin B is bypassed by extracorporeal circulation with
