KEFTAB vs ZINACEF IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalexin binds to penicillin-binding proteins (PBPs) on the bacterial cell wall, inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis via autolytic enzymes.
Cefuroxime is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking transpeptidation and leading to cell lysis and death.
Cefuroxime axetil (KEFTAB) 250-500 mg orally twice daily for 7-10 days. For uncomplicated urinary tract infections: 250 mg twice daily; for acute otitis media: 500 mg twice daily.
750 mg intravenously or intramuscularly every 8 hours; for severe infections, 1.5 g intravenously every 8 hours.

0.8-1.2 hours (prolonged to 6-8 hours in renal impairment; requires dose adjustment for CrCl <50 mL/min)
Terminal elimination half-life is approximately 1.5 hours in adults with normal renal function; prolonged to 3-4 hours in neonates and up to 20-30 hours in end-stage renal disease.
Renal: 90-95% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
Approximately 80-90% of the dose is excreted unchanged in the urine via glomerular filtration and tubular secretion; the remainder is eliminated via bile and feces.
