Tác dụng
Description:
Mechanism of Action: Ceftizoxime binds to 1 or more of the penicillin-binding proteins (PBPs) which inhibit the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death. Pharmacokinetics: Absorption: Time to peak plasma concentration: 1 hr. Distribution: Widely distributed in body tissues and fluids; occur in CSF (therapeutic concentrations) when meninges are inflamed. Crosses the placenta and enters breast milk (low concentrations). Plasma protein binding: 30%. Excretion: Via urine as unchanged drug w/in 24 hr. Plasma half-life: Approx 1.7 hr. |
