CEFADYL vs ZINACEF
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation.
Cefuroxime, a second-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
1-2 g IV/IM every 6 hours for moderate to severe infections; maximum 12 g/day.
750 mg IV/IM every 8 hours; for severe infections: 1.5 g IV every 8 hours; for life-threatening infections: 1.5 g IV every 6 hours

30-60 minutes in adults with normal renal function; prolonged to 10-20 hours in end-stage renal disease. Requires dose adjustment for CrCl <30 mL/min.
Terminal elimination half-life: 1.5-2 hours in adults with normal renal function; prolonged to 2.5-3.5 hours in elderly and up to 48 hours in end-stage renal disease.
Renal: 90-95% unchanged via glomerular filtration and tubular secretion. Biliary: <1%. Fecal: minimal.
Renal: 80-95% unchanged via glomerular filtration and tubular secretion; biliary: 5-10% excreted in feces; fecal: negligible.
