Abstract

A patient receiving polymyxin B sulfate intravenously for Gram-negative bacteremia developed progressive hyperchloremia and a negative "anion gap." Both abnormalities resolved following discontinuation of the drug. In vitro investigation suggested that the electrolyte abnormalities resulted from the polycationic properties of polymyxin B.
