Tác dụng
Description: Cefotetan is a 2nd generation cephalosporin which inhibits bacterial cell wall biosynthesis by binding to 1 or more of the penicillin-binding proteins (PBPs) which in turn prevents the final transpeptidation step of peptidoglycan synthesis, thus arresting cell wall assembly resulting in bacterial cell death.
Absorption: Time to peak plasma concentration: 1-3 hours (IM).
Distribution: Widely distributed into body tissues and fluids (including bile, gallbladder, kidney, skin, tonsils, uterus, sputum, prostatic and peritoneal fluids). Crosses the placenta and enters breast milk (small amounts). Plasma protein binding: Approx 88%.
Excretion: Via urine (approx 51-81% as unchanged drug). Elimination half-life: Approx 3-4.6 hours.
