CEPHRADINE vs ZEVTERA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephradine 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.
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.
250-500 mg orally every 6 hours; 500 mg to 1 g intramuscularly or intravenously every 6 hours. Maximum: 4 g/day.
400 mg intravenously every 8 hours

Terminal elimination half-life 0.5–1.5 hours (normal renal function); prolonged to 6–15 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.
Primarily renal (≥90% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal (<10%).
Approximately 70% of the dose is excreted unchanged in urine, with 20% recovered in feces via biliary elimination. Minor route: <5% as metabolites.
