代谢
米贝地尔经历的两个代谢途径是酯酶催化的酯侧链水解(产生醇代谢物)和细胞色素P450 3A4催化的氧化(在慢性给药过程中变得不那么重要)。代谢物的药理效果大约是母体米贝地尔的10%。
The two metabolic pathways that mibefradil undergoes are esterase-catalyzed hydrolysis of the ester side chain (producing an alcohol metabolite) and cytochrome P450 3A4-catalyzed oxidation (that becomes less important during chronic dosing). The pharmacologic effect of the metabolite is approximately 10% of that of the parent mibefradil.
