CECLOR vs TAZIDIME IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefaclor, a second-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It exhibits bactericidal activity against susceptible organisms.
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.
250 mg orally every 8 hours; for severe infections, 500 mg orally every 8 hours.
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: 0.6-0.9 hours in adults with normal renal function. Prolonged to 2-3 hours in end-stage renal disease. Half-life does not increase significantly with hepatic impairment.
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.
Primarily renal: 80-90% of unchanged drug excreted by glomerular filtration and tubular secretion within 8 hours. Biliary excretion accounts for <5%; fecal elimination negligible.
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <1%.
