CECLOR vs CEFOXITIN IN PLASTIC CONTAINER
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), leading to cell lysis and death. It exhibits bactericidal activity against susceptible organisms.
Cefoxitin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP1a, PBP1b, and PBP2, thereby inhibiting transpeptidation and leading to cell lysis. It is a cephamycin antibiotic resistant to beta-lactamase hydrolysis due to a 7-alpha-methoxy group.
250 mg orally every 8 hours; for severe infections, 500 mg orally every 8 hours.
1-2 g IV every 6-8 hours; maximum 12 g/day

Terminal elimination half-life: 0.6-0.9 hours in adults with normal renal function. Prolonged to 2-3 hours in end-stage renal disease. Half-life does not increase significantly with hepatic impairment.
Terminal elimination half-life: 0.7-1.5 hours (approximately 45-90 minutes); prolonged to 2-6 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 10-20 hours in severe renal impairment (CrCl <10 mL/min).
Primarily renal: 80-90% of unchanged drug excreted by glomerular filtration and tubular secretion within 8 hours. Biliary excretion accounts for <5%; fecal elimination negligible.
Renal: 85-95% unchanged via glomerular filtration and tubular secretion; biliary: <2%; fecal: trace.
