Capecitabine




How does it work?

This medicine contains capecitabine, which is an anti-cancer medicine known as a 'cytotoxic antimetabolite'. It is taken by mouth and is converted inside cancer cells to 5-fluorouracil (5-FU), the active form of the medicine. The conversion of capecitabine to 5-FU is carried out by several compounds within the body that are called enzymes. The enzyme responsible for the final step is found mostly in tumour tissues (although it is also found in other tissues in the body). This means that higher concentrations of the active 5-FU are produced within the tumour tissues, rather than other healthy areas of the body. The medicine is said to be targeted against the cancerous cells. Cancers form when cells within the body multiply abnormally and uncontrollably. These cells spread, destroying nearby tissues. 5-FU works by stopping the cancer cells from multiplying. It does this by inhibiting the production of the cells' genetic material, DNA and RNA. Both DNA and RNA are needed for growth and multiplication of cells. 5-FU causes a deficiency of DNA and RNA in the cancer cells, and this causes the cells to grow in an unbalanced way, resulting in the death of the cells. 5-FU can also affect normal, healthy cells, particularly those that multiply quickly, such as blood cells. However, because the capecitabine is mostly converted to 5-FU only in the cancer cells, it means that side effects on normal healthy cells are less with this medicine than with traditional 'non-targeted' 5-FU given via a drip. The most important side effect is on the bone marrow where blood cells are made. 5-FU can decrease the production of blood cells, leaving people susceptible to infection. Regular blood tests are therefore needed to monitor levels of blood cells. Capecitabine is used to treat colorectal cancer that has spread to other areas of the body, and breast cancer that is locally advanced or has spread to other areas of the body. For breast cancer, capecitabine is used as second-line treatment when previous chemotherapy has been unsuccessful. It is used either in combination with another anti-cancer medicine called docetaxol, (when previous chemotherapy included an anthracycline medicine), or on its own (when previous chemotherapy included a taxane and an anthracycline, or where further anthracycline treatment is not indicated).
