VELOSEF '125' vs ZINACEF IN PLASTIC CONTAINER
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), inhibiting peptidoglycan cross-linking, leading to cell lysis.
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.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.
750 mg intravenously or intramuscularly every 8 hours; for severe infections, 1.5 g intravenously every 8 hours.

Terminal elimination half-life: 0.5-1.0 hour (normal renal function); prolonged to 10-20 hours in severe renal impairment (CrCl <10 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: 80-90% 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.
