CEFIXIME vs VELOSEF '500'
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.
Cephradine inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting the final transpeptidation step of peptidoglycan synthesis, leading to cell lysis and death. It is a first-generation cephalosporin with bactericidal activity.
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 6 hours for 10 days.

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
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.
Terminal elimination half-life: 1.2 hours in adults with normal renal function; prolonged to 8-15 hours in severe renal impairment (CrCl <10 mL/min); clinical context: dosing interval adjustment required for renal impairment
Renal excretion of unchanged drug accounts for 50-60% of elimination; biliary/fecal elimination accounts for 10-20%.
Renal excretion of unchanged drug: >90% (glomerular filtration and tubular secretion); biliary/fecal: <1%
