KEFLEX vs KEFUROX 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), leading to cell lysis and death.
Cefuroxime is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-3 and PBP-1a/1b, leading to inhibition of transpeptidase activity and autolysin-mediated cell death.
250-500 mg orally every 6 hours; maximum 4 g/day.
750 mg to 1.5 g IV every 8 hours; for severe infections, up to 3 g IV every 8 hours.

0.5–1.2 hours in patients with normal renal function (CrCl >50 mL/min); prolonged to >20 hours in ESRD.
1.2-1.6 hours in adults with normal renal function. Extended to 15-22 hours in end-stage renal disease.
Primarily renal (90% or more unchanged via glomerular filtration and tubular secretion); small amounts biliary/fecal (<5%).
Renal: 80-90% unchanged by glomerular filtration and tubular secretion. Biliary: <2% excreted in bile. Fecal: <1%.
