CEFTRIAXONE vs CEFUROXIME
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Cefuroxime is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking and leading to cell lysis.
1-2 g IV/IM every 24 hours; maximum 4 g/day.
250-500 mg orally twice daily; 750 mg-1.5 g IV/IM every 8 hours for moderate infections; 1.5 g IV/IM every 8 hours for severe infections.

Clinical Note
moderateCefuroxime + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cefuroxime."
Clinical Note
moderateCeftriaxone + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Ceftriaxone."
Clinical Note
moderateCefuroxime + Cimetidine
"Cefuroxime can cause a decrease in the absorption of Cimetidine resulting in a reduced serum concentration and potentially a decrease in efficacy."
Clinical Note
moderateTerminal half-life: 5.8-8.7 hours in adults; prolonged to 12-24 hours in neonates and 30-90 hours in severe renal impairment.
Terminal elimination half-life is 1.2 hours in adults with normal renal function (increased to 15-22 hours in severe renal impairment [CrCl <10 mL/min], requiring dose adjustment).
Renal (33-67% unchanged) and biliary (up to 40%) with fecal elimination. In neonates, renal excretion is lower (~20%).
Renal excretion of unchanged drug accounts for 80-90% of elimination via glomerular filtration and tubular secretion; biliary/fecal excretion is minimal (<10%).
