CEFAZOLIN AND DEXTROSE vs VELOSEF '500'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal agent inhibiting bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis. Dextrose provides osmotic diuresis and energy source.
Cephradine inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting the final transpeptidation step of peptidoglycan synthesis, leading to cell lysis and death. It is a first-generation cephalosporin with bactericidal activity.
1-2 g IV/IM every 8 hours; maximum 12 g/day.
500 mg orally every 6 hours for 10 days.
