Lab Interactions

Food Interactions
Absorption delayed in the presence of food.
Mechanism of Actions
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.
Administration
May be taken with or without food. (May be taken w/ food or milk to reduce GI discomfort.)

Oral: Store below 25°C.
