Action
Description: Cefradine is a 1st-generation cephalosporin which inhibits the final transpeptidation step of the peptidoglycan synthesis in bacterial cell wall by binding to 1 or more of the penicillin-binding proteins (PBPs), thus arresting cell wall synthesis leading to bacterial cell death.
Pharmacokinetics:
Absorption: Rapidly and almost completely absorbed from the GI tract. Food may delay the rate but does not affect the extent of absorption. Time to peak plasma concentration: 1 hr (oral); w/in 1-2 hr (IM).
Distribution: Widely distributed to body tissues and fluids; CSF (insignificant amount). Crosses the placenta and enters breast milk (small amount). Plasma protein binding: Approx 8-12%.
Excretion: Via urine (oral: >90%; IM: 60-80%) as unchanged drug. Plasma half-life: Approx 1 hr.
