CEFTAZIDIME vs KEFTAB
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftazidime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has broad-spectrum activity against Gram-negative bacteria, including Pseudomonas aeruginosa.
Cephalexin binds to penicillin-binding proteins (PBPs) on the bacterial cell wall, inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis via autolytic enzymes.
1-2 g IV every 8 hours
Cefuroxime axetil (KEFTAB) 250-500 mg orally twice daily for 7-10 days. For uncomplicated urinary tract infections: 250 mg twice daily; for acute otitis media: 500 mg twice daily.

2 hours (range 1.2-2.2 h) in normal renal function; prolonged to 10-15 h in end-stage renal disease; requires dose adjustment.
0.8-1.2 hours (prolonged to 6-8 hours in renal impairment; requires dose adjustment for CrCl <50 mL/min)
Primarily renal: 80-90% excreted unchanged in urine via glomerular filtration; small amount (≈1%) biliary; ≤1% fecal.
Renal: 90-95% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
