Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefotetan is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, and activating autolytic enzymes.
Cefotaxime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-1A and PBP-3, leading to cell lysis and death.
1-2 g IV/IM every 12 hours for 5-10 days; up to 6 g/day for severe infections.
1-2 g IV/IM every 8 hours; maximum 12 g/day for severe infections.

Terminal elimination half-life: 4.5 hours (intravenous). In patients with renal impairment (CrCl <30 mL/min), half-life extends to approximately 20–30 hours, requiring dose adjustment.
Terminal elimination half-life is 0.9-1.5 hours in adults with normal renal function; prolonged to 2.5-10 hours in renal impairment (CrCl <20 mL/min). In neonates, half-life is 3-6 hours.
Primarily renal (unchanged); ~88% excreted in urine within 24 hours. Biliary/fecal elimination is negligible (<1% as metabolites).
Renal (50-60% unchanged), biliary (5-10%), with approximately 20-30% metabolized to desacetylcefotaxime (also renally eliminated). Total renal elimination of parent drug and metabolite accounts for >80%.
