Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking.
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 every 8 hours. For serious infections, up to 2 g IV every 6 hours.
1-2 g IV/IM every 8-12 hours; maximum 12 g/day for severe infections.

1.8 hours in normal renal function. Prolonged to 12-24 hours in end-stage renal disease (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.
Renal: 80-90% unchanged by glomerular filtration and tubular secretion. Biliary: minor (<1%). Fecal: negligible.
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%).
