CEPHAPIRIN SODIUM vs PRECEF
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Cefoperazone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
500 mg to 1 g IM or IV every 6 hours.
1-2 g IV every 6-8 hours; maximum 12 g/day.

0.5-1.0 hours; prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
0.5-1 hour in adults with normal renal function; prolonged to 2-8 hours in moderate to severe renal impairment (CrCl <30 mL/min).
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%.
Primarily renal (80-90% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal <10%.
