代谢
已经确定,孟鲁司特高度代谢,通常是通过细胞色素P450 3A4、2C8和2C9同工酶。特别是,CYP2C8酶在药物代谢中发挥重要作用。然而,在治疗剂量下,成年和儿科患者的稳态血浆中孟鲁司特代谢物的浓度是检测不到的。
It has been determined that montelukast is highly metabolized and typically so by the cytochrome P450 3A4, 2C8, and 2C9 isoenzymes. In particular, it seems that the CYP2C8 enzymes play a significant role in the metabolism of the drug. Nevertheless, at therapeutic doses, the plasma concentrations of montelukast metabolites are undetectable at steady state in adults and pediatric patients.
