概要
Mifepristone is a glucocorticoid receptor antagonist and CYP3A4 inhibitor, so it can reduce dexamethasone effect at the receptor while raising its levels. Mifepristone's label advises that corticosteroid treatment may be less effective. This is most relevant for systemic dexamethasone.
この相互作用をわかりやすく説明すると
Dexamethasone-neomycin-polymyxin and Mifepristone can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Dexamethasone-neomycin-polymyxin belongs to Anti Bacterial; Mifepristone belongs to Endocrine.
なぜ起こるのか
Glucocorticoid receptor antagonism by mifepristone plus CYP3A4 inhibition of dexamethasone metabolism.
対処法
With systemic dexamethasone, anticipate reduced response and higher steroid doses may be needed, with close monitoring. Avoid relying on corticosteroids in patients on chronic mifepristone, such as for Cushing syndrome.
