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), specifically PBP1a, PBP1b, PBP2a, PBP2b, PBP2x, PBP3, and PBP4, thereby preventing cross-linking of peptidoglycan chains. This leads to cell lysis and death.
Cefotetan is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and cross-linking of peptidoglycan. It has broad-spectrum activity against gram-negative and gram-positive bacteria, including anaerobes, and is resistant to beta-lactamases.
1-2 g IV/IM every 8 hours; maximum 12 g/day for severe infections.
1 to 2 g intravenously or intramuscularly every 12 hours for 5 to 10 days. Maximum dose 6 g daily.

Approximately 1.8 hours (range 1.2-2.2 h) in normal renal function; prolonged in renal impairment (up to 30-40 h in ESRD)
2.8-3.2 hours in normal renal function; prolonged to 12-30 hours in severe renal impairment (CrCl <10 mL/min).
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); minimal biliary (1-2%); fecal (<1%)
Primarily renal (76-85% unchanged in urine via glomerular filtration and tubular secretion); biliary excretion accounts for <10%, with small amounts in feces.
