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.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, leading to cell lysis.
1 to 2 g intravenously every 12 hours for 5 to 10 days. For severe infections, 2 g intravenously every 12 hours.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.

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).
Terminal elimination half-life: 0.5-1.0 hour (normal renal function); prolonged to 10-20 hours in severe renal impairment (CrCl <10 mL/min)
Primarily renal (unchanged drug) ~88%; minor biliary/fecal ~6-9%.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
