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.
Cefoperazone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan cross-linking and causing cell lysis.
250 mg orally every 8 hours; for severe infections, 500 mg orally every 8 hours.
2-4 g/day IV/IM divided q12h; severe infections: 6-12 g/day IV divided q8-12h

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.
2 hours (prolonged in hepatic impairment and neonates).
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 (80-90% unchanged in urine) and biliary (10-20%).
