Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalosporin antibiotic; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
Cefoperazone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
300 mg orally twice daily for 10 days; or 600 mg orally once daily for 10 days (for community-acquired pneumonia, acute exacerbations of chronic bronchitis, sinusitis, pharyngitis/tonsillitis, uncomplicated skin infections).
1-2 g IV every 6-8 hours; maximum 12 g/day.

1.7 hours (range 1.2–2.3 h) in healthy adults; prolonged to 3.2–6.6 h in renal impairment (CrCl <30 mL/min); no significant change in hepatic impairment.
0.5-1 hour in adults with normal renal function; prolonged to 2-8 hours in moderate to severe renal impairment (CrCl <30 mL/min).
Renal excretion as unchanged drug: 80-90% (primarily via glomerular filtration and tubular secretion); biliary/fecal: 10-20% (minor).
Primarily renal (80-90% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal <10%.
