Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
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.

500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.
