代谢
Samidorphan 主要通过 CYP3A4 代谢,CYP3A5、CYP2C19 和 CYP2C8 也有少量贡献。主要代谢产物是 RDC-9986(一种 N-脱烷基代谢物)和 RDC-1066(一种 N-氧化代谢物);尽管这两种代谢物对 μ-、κ- 和 δ- 阿片受体的亲和力达到了纳摩尔级别,但它们都不被认为对 samidorphan 的药理作用有所贡献。
Samidorphan is primarily metabolized by CYP3A4, with minor contributions from CYP3A5, CYP2C19, and CYP2C8. The main metabolism products are RDC-9986 (an N-dealkylated metabolite) and RDC-1066 (an N-oxide metabolite); although both metabolites have a nanomolar affinity for the μ-, κ-, and δ-opioid receptors, neither is thought to contribute to the pharmacological effects of samidorphan.
