SUBACUTE NEUROTOXICITY OF 5‐FLUOROURACIL and ITS DERIVATIVE, CARMOFUR, IN CATS
5'-fluorouracil and its derivative carmofur cause subacute neurotoxicity in cats, causing vacuolation and softening-like changes in the brain stem, with vacuolation due to direct toxic effects on myelin and softening due to local circulatory disturbances.

5-Fluorouracil and dihydropyrimidine dehydrogenase
DPD plays a crucial role in the pharmacokinetics of 5-fluorouracil, determining its toxicity and sensitivity in cancer chemotherapy, and drugs that control DPD activity can reduce toxicity and improve sensitivity.
