CECLOR vs CEFOTAN
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.
Cefotetan is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, and activating autolytic enzymes.
250 mg orally every 8 hours; for severe infections, 500 mg orally every 8 hours.
1-2 g IV/IM every 12 hours for 5-10 days; up to 6 g/day for severe infections.

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: 4.5 hours (intravenous). In patients with renal impairment (CrCl <30 mL/min), half-life extends to approximately 20–30 hours, requiring dose adjustment.
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.
Primarily renal (unchanged); ~88% excreted in urine within 24 hours. Biliary/fecal elimination is negligible (<1% as metabolites).
