Action
Description: Cefixime is a 3rd generation cephalosporin with bactericidal activity. It binds to 1 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 lysis and death.

Absorption: Bioavailability: 22-54%. Time to peak plasma concenration: 2-6 hours (susp); 3-8 hours (cap).
Distribution: Crosses the placenta. Plasma protein binding: Approx 65%, mainly to albumin.
Excretion: Mainly via urine (approx 50% as unchanged drug); faeces (10%).
