PENTACEF vs TAZIDIME IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), primarily PBP-3, leading to cell lysis and death. It is a beta-lactam antibiotic with activity against Gram-negative bacteria including Pseudomonas aeruginosa.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.
1-2 g intravenously every 8 hours for most infections; up to 2 g every 6 hours for severe infections, particularly in neutropenic patients or those with cystic fibrosis.

Terminal elimination half-life is 1.5-2 hours; prolonged to 3-5 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 10-20 hours in severe impairment (CrCl <10 mL/min); dosing adjustment required for CrCl <50 mL/min.
Terminal elimination half-life 1.7-2.0 hours in adults with normal renal function; prolonged to 12-30 hours in end-stage renal disease.
Approximately 80-90% renal excretion as unchanged drug via glomerular filtration and tubular secretion; 10-20% biliary/fecal elimination.
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <1%.
