私の夫が慢性骨髄性白血病診断されて24年になります。グリベッグ服用して24年、imatinib mesylate400mg 同様の薬なのでしょうか? 近い将来モニタリングの元で服薬を中止にすると主人は話しますが、中止してもよい薬でしょうか?

Rated 5 out of 5 by from KhanKhan, MS. et al. (PubMed 26161459) investigated the impact of CYP2C8*3 polymorphism on in vitro metabolism of imatinib to its metabolite N-Desmethyl Imatinib. They found CYP2C8*3 is a gain-of-function polymorphism for imatinib N-demethylation, which appears to be mainly mediated by CYP2C8 and not CYP3A4 in vitro in human liver microsomes. -SCBT Publication Review
