Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefizox (ceftizoxime) is a third-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and autolysin inhibition.
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.
1-2 g IV/IM every 8-12 hours; maximum 12 g/day for severe infections.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.

1.7-1.9 hours in adults; prolonged to 15-25 hours in severe renal impairment (CrCl <10 mL/min)
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)
Primarily renal (90-95% unchanged via glomerular filtration and tubular secretion); biliary (<1%); fecal (minimal)
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
