概要
Fezolinetant is cleared mainly by CYP1A2, and caffeine is a CYP1A2 substrate that can compete for this enzyme. Reduced clearance could raise fezolinetant exposure and increase the risk of adverse effects including liver injury. The labeled contraindication concerns CYP1A2 inhibitors; ordinary dietary caffeine is a weak interaction, but it is flagged here.
この相互作用をわかりやすく説明すると
Caffeine and Fezolinetant 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.
Caffeine belongs to Miscellaneous; Fezolinetant belongs to Endocrine.
なぜ起こるのか
Competition for CYP1A2 metabolism may reduce fezolinetant clearance and increase its plasma concentrations.
対処法
Counsel patients to limit caffeine intake, especially high doses or caffeine-containing medicines, during fezolinetant therapy. Monitor liver tests per fezolinetant labeling and for adverse effects.
