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.
Cefotetan is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), resulting in cell lysis and death.
1-2 g IV every 8 hours. For serious infections, up to 2 g IV every 6 hours.
1 to 2 g intravenously every 12 hours for 5 to 10 days. For severe infections, 2 g intravenously every 12 hours.

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 3-4 hours in normal renal function; prolonged in renal impairment (e.g., up to 13 hours in severe renal failure).
Renal: 80-90% unchanged by glomerular filtration and tubular secretion. Biliary: minor (<1%). Fecal: negligible.
Primarily renal (unchanged drug) ~88%; minor biliary/fecal ~6-9%.
