CEFOTAXIME SODIUM vs CEFTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefotaxime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-1A and PBP-3, leading to cell lysis and death.
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/IM every 8 hours; maximum 12 g/day for severe infections.
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.

Terminal elimination half-life is 0.9-1.5 hours in adults with normal renal function; prolonged to 2.5-10 hours in renal impairment (CrCl <20 mL/min). In neonates, half-life is 3-6 hours.
Terminal elimination half-life: 1-2 hours (normal renal function); prolonged to 15-20 hours in severe renal impairment (CrCl <10 mL/min).
Renal (50-60% unchanged), biliary (5-10%), with approximately 20-30% metabolized to desacetylcefotaxime (also renally eliminated). Total renal elimination of parent drug and metabolite accounts for >80%.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%.
