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), particularly PBP 3, leading to cell lysis and death. It has activity against both gram-positive and gram-negative bacteria.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
1-2 g intravenously every 8-12 hours; typical dose 1 g IV q12h for most infections, 2 g IV q8h for severe infections.
1-2 g IV/IM every 12-24 hours; maximum 4 g/day.

Approximately 2 hours in adults with normal renal function; prolonged to 4–8 hours in mild-to-moderate renal impairment and up to 13–30 hours in severe impairment (CrCl <30 mL/min).
Terminal elimination half-life is 5.8-8.7 hours in adults with normal renal and hepatic function. In neonates, half-life is prolonged (up to 16 hours). In patients with renal impairment, half-life increases to 12-18 hours; in hepatic impairment, it may be 15-20 hours. Dose adjustment is not typically required unless both renal and hepatic impairment are present.
Primarily renal (≥85% unchanged in urine via glomerular filtration and tubular secretion); biliary/fecal excretion minimal (<1%).
Ceftriaxone is eliminated 33-67% unchanged in urine via glomerular filtration and tubular secretion, and the remainder is excreted in feces (primarily as microbiologically inactive metabolites) via biliary secretion. Biliary excretion accounts for approximately 35-45% of total clearance.
