Polymyxin B

Polymyxin B

KEY POINTS

  • Polymyxin B works as a cationic detergent, damaging bacterial cytoplasmic membrane and causing leakage of intracellular contents
    • Polymyxin E (colistin, colistmethate sodium) is very similar to polymyxin B in spectrum and toxicity
      • See below resource “chalk and cheese” for a great comparison of the two
  • Available as injectable and is used topical intra-operative as well
  • Only used for Gram negative bacteria, like Pseudomonas aeruginosa and Acinetobacter baumannii
  • A last-line antibiotic and is typically only used when few to no other options exist
    • Strongly consider combination therapy when using this antibiotic
  • Highly associated with nephrotoxicity
