Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CEFMAX (cefepime) is a fourth-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-3 in Gram-negative bacteria and PBP-1a/1b in Gram-positive bacteria, thereby disrupting peptidoglycan cross-linking and leading to cell lysis. It has zwitterionic properties facilitating rapid penetration through Gram-negative outer membranes and is relatively resistant to hydrolysis by many beta-lactamases, including AmpC beta-lactamases.
Cefotaxime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), blocking transpeptidation, and activating autolytic enzymes.

1-2 g IV/IM every 8-12 hours; maximum 12 g/day for severe infections.

2–4 hours in adults with normal renal function; prolonged to 20–40 hours in severe renal impairment (CrCl <10 mL/min).
Terminal elimination half-life is approximately 0.6-1.2 hours in adults with normal renal function. In neonates, it is prolonged (2-6 hours). In renal impairment, half-life extends significantly (up to 15-30 hours in anuria), requiring dose adjustment.
Primarily renal (80–90% unchanged via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for <5%.
Primarily renal: approximately 60-80% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion. Small amounts are eliminated in bile (<10%) and feces (<1%).
