Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP1a, PBP1b, PBP2a, PBP2b, PBP2x, PBP3, and PBP4, thereby preventing cross-linking of peptidoglycan chains. This leads to cell lysis and death.
Ceftriaxone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has broad-spectrum activity against gram-positive and gram-negative bacteria.
1-2 g IV/IM every 8 hours; maximum 12 g/day for severe infections.
1-2 g IV/IM every 24 hours; maximum 4 g/day.

Clinical Note
moderateCeftriaxone + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Ceftriaxone."
Clinical Note
moderateCeftriaxone + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Ceftriaxone."
Clinical Note
moderateWarfarin + Ceftriaxone
"Warfarin may increase the anticoagulant activities of Ceftriaxone."
Clinical Note
moderatePhenprocoumon + Ceftriaxone
Approximately 1.8 hours (range 1.2-2.2 h) in normal renal function; prolonged in renal impairment (up to 30-40 h in ESRD)
Terminal half-life: 5.8-8.7 hours in adults; prolonged to 12-24 hours in neonates and 30-90 hours in severe renal impairment.
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); minimal biliary (1-2%); fecal (<1%)
Renal (33-67% unchanged) and biliary (up to 40%) with fecal elimination. In neonates, renal excretion is lower (~20%).
