Fluorouracil (51-21-8) | Anorexia | Synergistic | folic acid increases fluorouracil inhibition of thymidine formation which is important for DNA synthesis, and thereby increases fluorouracil toxicity. | Interaction of 5-fluorouracil with folates
|
Fluorouracil (51-21-8) | Bloody Diarrhoea | Synergistic | folic acid increases fluorouracil inhibition of thymidine formation which is important for DNA synthesis, and thereby increases fluorouracil toxicity. | Interaction of 5-fluorouracil with folates
|
Fluorouracil (51-21-8) | Mouth Ulceration | Synergistic | folic acid increases fluorouracil inhibition of thymidine formation which is important for DNA synthesis, and thereby increases fluorouracil toxicity. | Interaction of 5-fluorouracil with folates
|
Fluorouracil (51-21-8) | Vaginal Bleeding | Synergistic | folic acid increases fluorouracil inhibition of thymidine formation which is important for DNA synthesis, and thereby increases fluorouracil toxicity. | Interaction of 5-fluorouracil with folates
|
Phenytoin (57-41-0) | Seizure Control Is Partially Or Totally Lost | Antagonistic | Patients taking antiepileptics may have subnormal serum folic acid levels. Frequencies of 27 to 76% have been reported for phenobarbital, primidone, and phenytoin alone or in various ombinations.8 One possible explanation
is that this is due to the enzyme-inducing characteristics of these
antiepileptics, which makes excessive demands on folate for the synthesis
of the enzymes concerned with drug metabolism | Folic acid deficiency in patients receiving anticonvulsant drugs
