CEFTRIAXONE IN PLASTIC CONTAINER vs CEPHALOTHIN 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.
Cephalothin is a first-generation cephalosporin with bactericidal activity by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs).
1-2 g intravenously or intramuscularly every 12-24 hours, maximum 4 g daily.
1-2 g IV every 4-6 hours; maximum 12 g/day.

5.8-8.7 hours in adults; prolonged in neonates (18-25 h), elderly, and renal impairment.
Terminal elimination half-life: 0.5-1.0 hour in adults with normal renal function. In anuria, prolonged to 2.5-8 hours. Dose adjustment required for CrCl <50 mL/min.
Renal (33-67% as unchanged drug), biliary/fecal (24-44% as active drug and metabolites).
Primarily renal (60-90% unchanged via glomerular filtration and tubular secretion). Minor biliary excretion (1-5%). Fecal elimination negligible.
