Tác dụng
Description:
Mechanism of Action: Delamanid is a nitroimidazo-oxazole antimycobacterial prodrug that is activated through bioreduction of its nitro group by Mycobacterium tuberculosis. It inhibits the synthesis of mycobacterial cell wall components, methoxymycolic and ketomycolic acids. Pharmacokinetics: Absorption: Increased bioavailability with food. Distribution: Widely distributed throughout the body. Plasma protein binding: ≥99.5%. Metabolism: Metabolised mainly in plasma by albumin and to a lesser extent via hydroxylation and oxidation by CYP3A4 enzymes to form DM-6705. Excretion: Mainly via faeces. Elimination half-life: Approx 30-38 hours. |
