Colistin

  • For the past fifty years, the inactive prodrug colistin methanesulfonate has been sold alongside colistin (also known as polymyxin E). The medication was one of the first antibiotics to show against Gram-negative bacteria, especially Pseudomonas aeruginosa. It has a rapid bactericidal activity that is concentration-dependent. Bacillus colistin produces a cyclic polypeptide antibiotic. Polymyxins E1 and E2 (also known as Colistins A, B, and C) are detergents that function on cell membranes. Colistin is less toxic than Polymyxin B, but otherwise, they are very similar.

    The gene has the ability to spread rapidly to other bacteria, increasing the risk that bacteria that are already immune to major antibiotics will also become resistant to colistin. Colistin is an important last-ditch choice. Because of its side effects, the medication is seldom used in routine treatment.
    Colistin can be given as an aerosol or as an intramuscular or intravenous injection after reconstitution with 0.9 percent sodium chloride injection or sterile water for injection. When necessary, however, colistin may be administered in other ways, such as intrathecally.
    Intravenous polymyxin B and colistin have recently become more widely used in the treatment of otherwise pan-resistant nosocomial infections, especially those caused by Pseudomonas and Acinetobacter spp. They're also used in aerosol form for cystic fibrosis patients.
