CECLOR CD vs CEFOTAXIME SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefaclor, a second-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking.
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.
250-500 mg orally every 8 hours; extended-release form (CECLOR CD) 375-750 mg orally every 12 hours.
1-2 g IV/IM every 8 hours; maximum 12 g/day for severe infections.

Terminal elimination half-life: ~0.6-0.9 hours (prolonged in renal impairment)
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.
Renal: ~80% unchanged; biliary/fecal: ~20%
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%.
