Classifications ⬆ ⬇

Therapeutic Classification: antineoplastics

Pharmacologic Classification: antimetabolites

Indications ⬆ ⬇

High Alert


Action ⬆ ⬇

  • Converted in tissue to 5-fluorouracil, which inhibits DNA and RNA synthesis by preventing thymidine production.
  • The enzyme responsible for the final step in the conversion to 5-fluorouracil may be found in higher concentrations in some tumors.
Therapeutic effects:
  • Decreased spread of colorectal, breast, gastric, esophageal, gastroesophageal junction, and pancreatic cancer.

Pharmacokinetics ⬆ ⬇

Absorption: Well absorbed after oral administration.

Distribution: Unknown.

Metabolism/Excretion: Metabolized mostly in tissue and by the liver to 5-fluorouracil; 5-fluorouracil is metabolized by dihydropyrimidine dehydrogenase to a less toxic compound; inactive metabolites are excreted primarily in urine.

Half-Life: 45 min.
