Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
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.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.

Terminal elimination half-life is 1.5-2 hours; prolonged to 3-5 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 10-20 hours in severe impairment (CrCl <10 mL/min); dosing adjustment required for CrCl <50 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)
Approximately 80-90% renal excretion as unchanged drug via glomerular filtration and tubular secretion; 10-20% biliary/fecal elimination.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
