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.
Ceftobiprole, the active moiety of ZEVTERA, is a cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), including PBP2a in methicillin-resistant Staphylococcus aureus (MRSA), leading to cell death.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.
400 mg 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 3.5 hours in patients with normal renal function. In moderate renal impairment (CrCl 30-50 mL/min), half-life extends to ~6 hours, requiring dose adjustment.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
Approximately 70% of the dose is excreted unchanged in urine, with 20% recovered in feces via biliary elimination. Minor route: <5% as metabolites.
