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), 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.
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 or intramuscularly every 12 hours for 5 to 10 days. Maximum dose 6 g daily.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.

2.8-3.2 hours in normal renal function; prolonged to 12-30 hours in severe renal impairment (CrCl <10 mL/min).
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 (76-85% unchanged in urine via glomerular filtration and tubular secretion); biliary excretion accounts for <10%, with small amounts in feces.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
