Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftazidime is a third-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-3, leading to cell lysis and death.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, leading to cell lysis.
2 g intravenously every 8 hours for serious infections; 1 g intravenously every 8 hours for uncomplicated infections.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.
