CECLOR CD vs PRECEF
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.
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.
250-500 mg orally every 8 hours; extended-release form (CECLOR CD) 375-750 mg orally every 12 hours.
1-2 g IV every 6-8 hours; maximum 12 g/day.

Terminal elimination half-life: ~0.6-0.9 hours (prolonged in renal 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: ~80% unchanged; biliary/fecal: ~20%
Primarily renal (80-90% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal <10%.
