What is the therapeutic action of capecitabine?

Capecitabine is a chemotherapeutic drug that is taken orally and is used to treat metastatic breast and colorectal cancers. Capecitabine is a prodrug that is metabolized to fluorouracil (antimetabolite) in the tumor, where it inhibits DNA synthesis and reduces tumor development.

What is capecitabine used for in cancer?

Capecitabine is an antimetabolite, which is a kind of chemotherapy medication. Capecitabine is broken down in the body into chemicals that interfere with the creation of DNA, RNA, and proteins. This prevents cancer cells from multiplying.

Why is capecitabine used with radiation?

To eliminate tumor cells, radiation treatment employs high-energy X-rays. Capecitabine may potentially increase the sensitivity of tumor cells to radiation treatment. Following surgery, using radiation together with capecitabine may eliminate any residual tumor cells.
