CEFOTAN vs KEFZOL
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.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting 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 8 hours for moderate to severe infections; maximum 12 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.
1.5-2 hours in adults with normal renal function; prolonged to 20-30 hours in end-stage renal disease (CrCl <10 mL/min).
Primarily renal (unchanged); ~88% excreted in urine within 24 hours. Biliary/fecal elimination is negligible (<1% as metabolites).
Renal: 80-90% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: minimal (<5%).
