<unk>  interacts strongly and in some cases lethally with fluorouracil (5-FU), its prodrugs and related substances. This is based on the metabolite bromovinyluracil (BVU), which irreversibly inhibits the enzyme dihydropyrimidine dehydrogenase (DPD) which is necessary for inactivating 5-FU. The closely related drug brivudine has the same interaction. Bromovinyluracil (BVU)
