CEFOTAXIME vs CEFTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefotaxime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
Ceftin (cefuroxime axetil) is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically transpeptidases, thereby disrupting peptidoglycan cross-linking. This leads to cell lysis and death primarily during active cell division.
1-2 g IV every 6-8 hours; maximum 12 g/day. For uncomplicated infections: 1 g IV every 8-12 hours.
250-500 mg orally twice daily for 10 days; for community-acquired pneumonia, 500 mg twice daily for 10 days. Intravenous: 750-1500 mg every 8 hours.

Clinical Note
moderateCefotaxime + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cefotaxime."
Clinical Note
moderateCefotaxime + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefotaxime."
Clinical Note
moderateWarfarin + Cefotaxime
"Warfarin may increase the anticoagulant activities of Cefotaxime."
Clinical Note
moderatePhenprocoumon + Cefotaxime
Terminal elimination half-life: 1-1.5 hours in adults with normal renal function. In neonates, it is prolonged to 2-4 hours. In severe renal impairment (CrCl <20 mL/min), half-life extends up to 10-15 hours, requiring dose adjustment.
Terminal elimination half-life: 1-2 hours (normal renal function); prolonged to 15-20 hours in severe renal impairment (CrCl <10 mL/min).
Approximately 80-90% of the dose is excreted unchanged in the urine via glomerular filtration and tubular secretion. About 5-10% is excreted in bile and feces as desacetylcefotaxime, the active metabolite.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%.
