Polymyxin B-Induced Kidney Injury Assessment of a Novel Formulation of Polymyxin B (VRP-034) in Rats
Despite the crucial role of Polymyxin-B in treating life-threatening gram-negative infections, its clinical utility is limited due to the risk of acute kidney injury.

Novel polymyxin derivatives are less cytotoxic than polymyxin B to renal proximal tubular cells
The emergence of very multiresistant Gram-negative bacterial strains has reinstated polymyxins (polymyxin B, colistin), pentacationic lipopeptides, in the therapy, in spite of their nephrotoxicity. Extensive tubular reabsorption concentrates polymyxin in

Polymyxin B broth disk elution as a screening test to determine polymyxin B susceptibility in enterobacterales [PDF]
Detection of polymyxins susceptibility by clinical laboratories is a nightmare mainly because of physicochemical properties of the drug. The aim of this study was to evaluate accuracy of Polymyxin B Broth Disk Elution (PBDE), as screening test, compared ...
