CEFEPIME HYDROCHLORIDE vs CEFTRIAXONE SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase and carboxypeptidase activity, leading to cell lysis.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
1-2 g IV every 8-12 hours; for uncomplicated urinary tract infections, 500 mg IV every 12 hours.
1-2 g IV/IM every 12-24 hours; maximum 4 g/day.

2-2.3 hours in healthy adults (prolonged to 13-15 hours in severe renal impairment; requires dosage adjustment).
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 via glomerular filtration and tubular secretion); biliary/fecal <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.
