CEPHALOTHIN SODIUM vs FORTAZ IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalothin is a first-generation cephalosporin with bactericidal activity by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs).
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP3, thereby disrupting peptidoglycan cross-linking and leading to cell lysis. It is a third-generation cephalosporin with broad-spectrum activity against Gram-negative bacteria, including Pseudomonas aeruginosa.
1-2 g IV every 4-6 hours; maximum 12 g/day.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.

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.
1.8 hours in normal adults; prolonged to 3-5 hours in neonates and 10-30 hours in severe renal impairment (CrCl <10 mL/min)
Primarily renal (60-90% unchanged via glomerular filtration and tubular secretion). Minor biliary excretion (1-5%). Fecal elimination negligible.
