ANSPOR vs CECLOR CD
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
Cefaclor, a second-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking.
250-500 mg orally every 6 hours for 10-14 days; maximum 4 g/day.
250-500 mg orally every 8 hours; extended-release form (CECLOR CD) 375-750 mg orally every 12 hours.

1.5–2 hours in adults with normal renal function; prolonged to 20–30 hours in severe renal impairment (CrCl <10 mL/min)
Terminal elimination half-life: ~0.6-0.9 hours (prolonged in renal impairment)
Primarily renal (90–95%) as unchanged drug via glomerular filtration and tubular secretion; biliary excretion negligible (<1%)
Renal: ~80% unchanged; biliary/fecal: ~20%
