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.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
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 12-24 hours; maximum 4 g/day.

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 5.8-8.7 hours in adults with normal renal and hepatic function. In neonates, half-life is prolonged (up to 16 hours). In patients with renal impairment, half-life increases to 12-18 hours; in hepatic impairment, it may be 15-20 hours. Dose adjustment is not typically required unless both renal and hepatic impairment are present.
Primarily renal (unchanged); ~88% excreted in urine within 24 hours. Biliary/fecal elimination is negligible (<1% as metabolites).
Ceftriaxone is eliminated 33-67% unchanged in urine via glomerular filtration and tubular secretion, and the remainder is excreted in feces (primarily as microbiologically inactive metabolites) via biliary secretion. Biliary excretion accounts for approximately 35-45% of total clearance.
