Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefepime is a fourth-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking. It has enhanced activity against Gram-negative bacteria due to rapid penetration through the outer membrane and low affinity for β-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.
1-2 g IV every 8-12 hours for most indications; maximum 2 g every 8 hours for severe infections.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.

Terminal elimination half-life is approximately 2-2.5 hours in adults with normal renal function; extends to 8-12 hours in moderate renal impairment (CrCl 30-60 mL/min) and up to 20-24 hours in severe impairment (CrCl < 30 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 (approximately 80-90% as unchanged drug) via glomerular filtration and tubular secretion; biliary/fecal excretion is minimal (< 1%).
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
