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), resulting in cell lysis and death.
Cephalothin is a first-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking peptidoglycan cross-linking. It has activity against gram-positive cocci (e.g., Staphylococcus aureus, Streptococcus pyogenes) and some gram-negative bacilli (e.g., Escherichia coli, Klebsiella pneumoniae).
1 to 2 g intravenously every 12 hours for 5 to 10 days. For severe infections, 2 g intravenously every 12 hours.
1-2 g IV every 4-6 hours; maximum 12 g/day.

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).
0.5-1 hour in patients with normal renal function; prolonged to 2-8 hours in moderate renal impairment (CrCl 30-50 mL/min); up to 20-30 hours in end-stage renal disease; due to rapid elimination, frequent dosing (q4-6h) is required for continuous bactericidal levels.
Primarily renal (unchanged drug) ~88%; minor biliary/fecal ~6-9%.
Primarily renal (60-90% unchanged) via tubular secretion and glomerular filtration; minor biliary excretion (less than 5%); hepatic metabolism to desacetylcephalothin (active but less potent) accounts for about 20-30% of dose; fecal elimination negligible.
