Description
Mechanism of Action
Ceftriaxone 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: Peak plasma concentrations after 2 hr (IM).
Distribution: Distributed widely into body tissues and fluids; CSF (therapeutic concentrations). Crosses the placenta and enters breast milk; bile (high concentrations). Protein-binding: 85-95%.
Excretion: Via the urine (40-65% as unchanged); via the bile to the faeces (remainder as unchanged and microbiologically inactive compounds); 6-9 hr (elimination half-life).
