ANSPOR vs CEFTIN
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.
Ceftin (cefuroxime axetil) is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically transpeptidases, thereby disrupting peptidoglycan cross-linking. This leads to cell lysis and death primarily during active cell division.
250-500 mg orally every 6 hours for 10-14 days; maximum 4 g/day.
250-500 mg orally twice daily for 10 days; for community-acquired pneumonia, 500 mg twice daily for 10 days. Intravenous: 750-1500 mg every 8 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: 1-2 hours (normal renal function); prolonged to 15-20 hours in severe renal impairment (CrCl <10 mL/min).
Primarily renal (90–95%) as unchanged drug via glomerular filtration and tubular secretion; biliary excretion negligible (<1%)
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%.
