Cefixime is an oral third generation cephalosporin antibiotic. It is used to treat gonorrhea, tonsilitis, and pharyngitis. The usual dose is 400 mg in two divided doses for up to 5-7 days.

In India it is available under brand names, such as, SECEF (Novartis ), Zeefix (Agio Pharmaceuticals Ltd.);Cefigard 50DT, 100DT, 200DT, Dry syrup(Vanguard therapetics Pvt Ltd), Ceftas-200 (Intas Pharmaceuticals); ZiFi CV-200 (FDC Limited) Alfi (Alkem Laboratories).

Pharmacodynamics

Pharmacokinetics

Cefixime binds to one or more of the penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.

Absorption
Only 40-50% is absorbed from the GI tract (oral); rate may be decreased if taken with food. Greater absorption from oral suspension than tablets.

Distribution
Bile, urine (high concentrations); crosses the placenta. Protein-binding: 65%.

Excretion
20% of an oral dose excreted via urine unchanged; 60% nonrenal elimination; some is excreted via the faeces from the bile. Substantially removed by dialysis.
