概要
Sepiapterin must be reduced by dihydrofolate reductase to produce tetrahydrobiopterin. Methotrexate inhibits this enzyme and may reduce BH4 formation and weaken control of phenylalanine.
この相互作用をわかりやすく説明すると
Methotrexate and Sepiapterin 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.
Methotrexate belongs to Oncology; Sepiapterin belongs to Miscellaneous.
なぜ起こるのか
DHFR inhibition by methotrexate impairs conversion of sepiapterin to BH4.
対処法
Avoid the combination if possible. If unavoidable, monitor blood phenylalanine closely and adjust treatment.
