CEFAZOLIN SODIUM vs KEFLET
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), specifically PBP1a, PBP1b, PBP2a, PBP2b, PBP2x, PBP3, and PBP4, thereby preventing cross-linking of peptidoglycan chains. This leads to cell lysis and death.
Keflet (warfarin) inhibits vitamin K epoxide reductase, preventing the recycling of vitamin K and thereby reducing the synthesis of clotting factors II, VII, IX, and X in the liver.
1-2 g IV/IM every 8 hours; maximum 12 g/day for severe infections.
500 mg orally every 12 hours for 10-14 days; for uncomplicated UTI: 250 mg orally every 12 hours for 7 days.
