Tegafur (INN, BAN, USAN) is a chemotherapeutic fluorouracil prodrug used in the treatment of cancers. It is a component of the combination drug tegafur/uracil. When metabolised, it becomes 5-fluorouracil.[1]

Medical uses

As a prodrug to 5-FU it is used in the treatment of the following cancers:[2]

It is often given in combination with drugs that alter its bioavailability and toxicity such as gimeracil, oteracil or uracil.[2] These agents achieve this by inhibiting the enzyme dihydropyrimidine dehydrogenase (uracil/gimeracil) or orotate phosphoribosyltransferase (oteracil).[2]

Adverse effects

The major side effects of tegafur are similar to fluorouracil and include myelosuppression, central neurotoxicity and gastrointestinal toxicity (especially diarrhoea).[2] Gastrointestinal toxicity is the dose-limiting side effect of tegafur.[2] Central neurotoxicity is more common with tegafur than with fluorouracil.[2]

Mechanism of action

It is a prodrug to fluorouracil which is a thymidylate synthase inhibitor.[2]

Pharmacokinetics

It is metabolised into fluorouracil by CYP2A6.[4][5]
