CEFAZOLIN IN DEXTROSE vs VELOSEF '125'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking.
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 every 8 hours. For serious infections, up to 2 g IV every 6 hours.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.

1.8 hours in normal renal function. Prolonged to 12-24 hours in end-stage renal disease (CrCl <10 mL/min).
Terminal elimination half-life: 0.5-1.0 hour (normal renal function); prolonged to 10-20 hours in severe renal impairment (CrCl <10 mL/min)
Renal: 80-90% unchanged by glomerular filtration and tubular secretion. Biliary: minor (<1%). Fecal: negligible.
