CEFTRIAXONE IN PLASTIC CONTAINER vs CEPHAPIRIN SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis mediated by autolytic enzymes. It has broad-spectrum activity against gram-positive and gram-negative bacteria.
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 intravenously or intramuscularly every 12-24 hours, maximum 4 g daily.
500 mg to 1 g IM or IV every 6 hours.

5.8-8.7 hours in adults; prolonged in neonates (18-25 h), elderly, and renal impairment.
0.5-1.0 hours; prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Renal (33-67% as unchanged drug), biliary/fecal (24-44% as active drug and metabolites).
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%.
