CEFTRIAXONE vs KEFLIN IN PLASTIC CONTAINER
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.
Cephalothin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activity, leading to cell lysis and death.

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.
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
0.5-1 hour in normal renal function; prolonged to 20-30 hours in severe renal impairment (CrCl <10 mL/min)
Renal (33-67% unchanged) and biliary (up to 40%) with fecal elimination. In neonates, renal excretion is lower (~20%).
Renal: 60-80% unchanged; biliary/fecal: minimal (<1%)
