代谢
拉米地坦的肝脏和肝脏外代谢主要由非CYP酶催化,酮还原似乎是其主要途径。尽管尚未阐明参与拉米地坦代谢的具体酶,但FDA的标签指出以下酶不参与其代谢:单胺氧化酶、CYP450还原酶、黄嘌呤氧化酶、乙醇脱氢酶、乙醛脱氢酶和aldo-酮还原酶。拉米地坦的代谢物在已发表的研究中尚未被表征,但其两个代谢物(M7和M18)被认为是药理学上不活跃的。
The hepatic and extra-hepatic metabolism of lasmiditan is catalyzed primarily by non-CYP enzymes, with ketone reduction appearing to be the primary pathway. While the specific enzymes involved in the metabolism of lasmiditan have not been elucidated, FDA labeling states that the following enzymes are _not_ involved in its metabolism: monoamine oxidases, CYP450 reductase, xanthine oxidase, alcohol dehydrogenase, aldehyde dehydrogenase, and aldo-keto reductases. The metabolites of lasmiditan have not been characterized in published research, but two of its metabolites (M7 and M18) are considered to be pharmacologically inactive.
