Description and Uses
Like other third-generation cephalosporins, it has excellent anti-Gram-negative activity and is useful institutionally. It has a metabolically vulnerable acetoxy group attached to C-3 and loses approximately 90% of its activity when this is hydrolyzed. This metabolic feature also complicates the pharmacokinetic data, because both active forms are present and have different properties. Cefotaxime should be protected from heat and light and may color slightly without significant loss of potency. Like other third-generation cephalosporins, cefotaxime has less activity against staphylococci but has greater activity against Gram-negative organisms.
