Capecitabine , sold under the brand name Xeloda among others, is a anticancer medication used to treat breast cancer , gastric cancer and colorectal cancer .[3] For breast cancer it is often used together with docetaxel .[4] It is taken by mouth .[4]
Common side effects include abdominal pain, vomiting, diarrhea , weakness, and rashes.[4] Other severe side effects include blood clotting problems, allergic reactions , heart problems such as cardiomyopathy , and low blood cell counts .[4] Use during pregnancy may result in harm to the fetus.[4] Capecitabine, inside the body, is converted to 5-fluorouracil (5-FU) through which it acts.[4] It belongs to the class of medications known as fluoropyrimidines , which also includes 5-FU and tegafur .[5]
Capecitabine was patented in 1992 and approved for medical use in 1998.[6] It is on the World Health Organization's List of Essential Medicines .[7]
Medical uses
[ edit ]
Capecitabine is indicated for
adjuvant treatment of people with Stage III colon cancer as a single agent or as a component of a combination chemotherapy regimen;[8]
perioperative treatment of adults with locally advanced rectal cancer as a component of chemoradiotherapy;[8]
treatment of people with unresectable or metastatic colorectal cancer as a single agent or as a component of a combination chemotherapy regimen;[8]
treatment of people with advanced or metastatic breast cancer as a single agent if an anthracycline- or taxane-containing chemotherapy is not indicated;[8]
treatment of people with advanced or metastatic breast cancer in combination with docetaxel after disease progression on prior anthracycline-containing chemotherapy;[8]
treatment of adults with unresectable or metastatic gastric, esophageal, or gastroesophageal junction cancer as a component of a combination chemotherapy regimen;[8]
treatment of adults with HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma who have not received prior treatment for metastatic disease as a component of a combination regimen;[8]
adjuvant treatment of adults with pancreatic adenocarcinoma as a component of a combination chemotherapy regimen.[8]
Adverse effects

Notes on adverse effects:
Contraindications
[ edit ]
Contraindications include:[11]
Drug interactions
[ edit ]
Drugs it is known to interact with include:[11]
Sorivudine or its analogues, such as, brivudine .
CYP2C9 substrates, including, warfarin and other coumarin-derivatives anticoagulants
Phenytoin , as it increases the plasma concentrations of phenytoin.
Calcium folinate may enhance the therapeutic effects of capecitabine by means of synergising with its metabolite, 5-FU. It may also induce more severe diarrhoea by means of this synergy.[14]
Pharmacogenetics
[ edit ]
The dihydropyrimidine dehydrogenase (DPD) enzyme is responsible for the detoxifying metabolism of fluoropyrimidines, a class of drugs that includes capecitabine, 5-fluorouracil and tegafur .[5] Genetic variations within the DPD gene (DPYD ) can lead to reduced or absent DPD activity, and individuals who are heterozygous or homozygous for these variations may have partial or complete DPD deficiency ; an estimated 0.2% of individuals have complete DPD deficiency .[5] [15] Those with partial or complete DPD deficiency have a significantly increased risk of severe or even fatal drug toxicities when treated with fluoropyrimidines; examples of toxicities include myelosuppression , neurotoxicity and hand-foot syndrome .[5] [15]

Fluorouracil (5-FU) Activity edit
Capecitabine is metabolised to 5-FU which in turn is a thymidylate synthase inhibitor, hence inhibiting the synthesis of thymidine monophosphate (ThMP), the active form of thymidine which is required for the de novo synthesis of DNA.[16]
