Background

Cefotaxime is a bactericidal, time-dependent third generation cephalosporin (╬▓-lactam) antibiotic with increased activity against Gram-negative bacteria such as Enterobacteriaceae when compared to first and second generation cephalosporins (e.g. cefazolin). It is not effective against Enterococcus spp. and Pseudomonas aeruginosa, and has less efficacy against anaerobes than second generation cephalosporins. Distribution throughout the body is wide, and cefotaxime crosses the blood-brain barrier. Excretion is primarily in urine.
