代谢
格列吡嗪受肝脏代谢的影响,其主要代谢物是通过芳香羟基化形成的。这些主要代谢物据报道在药理上是无效的。相比之下,形成的一个次要代谢物是乙酰氨基乙基苯衍生物,它占初始剂量的不到2%,并且据报道其降糖活性是母体化合物的十分之一到三分之一。
Glipizide is subject to hepatic metabolism, in which its major metabolites are formed from aromatic hydroxylation. These major metabolites are glipizide are reported to be pharmacologically inactive. In contrast, an acetylaminoethyl benzine derivative is formed as a minor metabolite which accounts for less than 2% of the initial dose and is reported to have one-tenth to one-third as much hypoglycemic activity as the parent compound.
