CEPHALOTHIN SODIUM vs KEFLET
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalothin is a first-generation cephalosporin with bactericidal activity by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs).
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 every 4-6 hours; maximum 12 g/day.
500 mg orally every 12 hours for 10-14 days; for uncomplicated UTI: 250 mg orally every 12 hours for 7 days.

Terminal elimination half-life: 0.5-1.0 hour in adults with normal renal function. In anuria, prolonged to 2.5-8 hours. Dose adjustment required for CrCl <50 mL/min.
0.5-1 hour; prolonged in renal impairment (up to 20-30 hours in ESRD).
Primarily renal (60-90% unchanged via glomerular filtration and tubular secretion). Minor biliary excretion (1-5%). Fecal elimination negligible.
Renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal < 5%.
