CEFAZOLIN IN DEXTROSE vs CEPHAPIRIN SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking.
Cephapirin sodium is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), primarily PBP1 and PBP3, thereby inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis mediated by autolytic enzymes.
1-2 g IV every 8 hours. For serious infections, up to 2 g IV every 6 hours.
500 mg to 1 g IM or IV every 6 hours.

1.8 hours in normal renal function. Prolonged to 12-24 hours in end-stage renal disease (CrCl <10 mL/min).
0.5-1.0 hours; prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Renal: 80-90% unchanged by glomerular filtration and tubular secretion. Biliary: minor (<1%). Fecal: negligible.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%.
