Capecitabine is a prodrug of fluorouracil, a pyrimidine antimetabolite, which is metabolised into 5-fluoro-2′-deoxyuridine-5′monophosphate (FdUMP) and 5-fluorouridine triphosphate (FUTP). FdUMP covalently binds to thymidylate synthase, inhibiting the formation of thymidilate, thus interfering with DNA synthesis. Additionally, FUTP interferes with RNA synthesis.

Pregnancy Category D. There is positive evidence of human fetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).

Precaution: Hepatic dysfunction, bone marrow suppression, poor nutritional status, warfarin therapy. Child, elderly, prior extensive pelvic radiation or alkylating therapy. Moderate renal impairment; CBC with differential; monitor hepatic and renal function. Discontinue use if intractable diarrhoea, stomatitis, bone marrow suppression or MI develops.

The manifestations of acute overdose include nausea, vomiting, diarrhea, mucositis, gastrointestinal irritation and bleeding, and bone marrow depression. Medical management of overdose should include customary therapeutic and supportive medical interventions aimed at correcting the presenting clinical manifestations and preventing their possible complications.

Keep in a dry place and store below 30°C. Protect from light and keep out of the reach of children.

Cytotoxic Chemotherapy

Capecitabine is a prodrug that is converted to fluorouracil following oral administration, which in turn inhibits thymidylate synthetase, blocking the methylation of deoxyuridylic acid to thymidylic acid, interfering with DNA, and to a lesser degree, RNA synthesis.
