ANSPOR vs CLAFORAN
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.
Cefotaxime is a bactericidal cephalosporin antibiotic that 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.
1-2 g IV/IM every 8 hours. Maximum dose: 12 g/day in divided doses.

1.5–2 hours in adults with normal renal function; prolonged to 20–30 hours in severe renal impairment (CrCl <10 mL/min)
0.8-1.4 hours in normal renal function (prolonged to 11-30 hours in severe renal impairment, CrCl <10 mL/min). No clinically relevant accumulation with standard dosing in renal impairment with dose adjustment.
Primarily renal (90–95%) as unchanged drug via glomerular filtration and tubular secretion; biliary excretion negligible (<1%)
Primarily renal (80-90% unchanged in urine via glomerular filtration and tubular secretion); biliary/fecal <10%.
