FORTAZ IN PLASTIC CONTAINER vs VELOSEF '125'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
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.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.
