代谢
Levamlodipine是一种药物,它主要通过肝脏中的CYP3A4酶代谢,其中90%的代谢物都是无活性的。在人类肝脏微体中,Levamlodipine的脱氢作用形成吡啶代谢物(M9)是最重要的代谢途径。这种代谢物可以进一步发生氧化脱氨或O-脱烷基化反应,但它似乎不会像外消旋体氨氯地平那样发生O-脱甲基反应。
Levamlodipine is 90% metabolized to inactive metabolites. Incubation with liver microsomes has shown that this metabolism is primarily mediated by CYP3A4. Levamlodipine's dehydrogenation to a pyridine metabolite (M9) is the most important metabolic pathway in human liver microsomes. This derivative can be further oxidatively deaminated or O-dealkylated, but does not appear to undergo O-demethylation like racemic amlodipine.
