CEFIXIME vs KEFLET
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefixime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading 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.
400 mg orally once daily or 200 mg orally every 12 hours for 7–14 days; uncomplicated gonorrhea: 400 mg orally as a single dose
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 is 3-4 hours in patients with normal renal function; extends to 11-15 hours in moderate renal impairment (CrCl 20-40 mL/min) and up to 20 hours in severe impairment.
Clinical Note
moderateCefixime + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cefixime."
Clinical Note
moderateCefixime + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefixime."
Clinical Note
moderateWarfarin + Cefixime
"Warfarin may increase the anticoagulant activities of Cefixime."
Clinical Note
moderatePhenprocoumon + Cefixime
0.5-1 hour; prolonged in renal impairment (up to 20-30 hours in ESRD).
Renal excretion of unchanged drug accounts for 50-60% of elimination; biliary/fecal elimination accounts for 10-20%.
Renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal < 5%.
