Capecitabine is rapidly absorbed by the intestinal mucosa after oral administration, and then converted into an inactive intermediate 5'-deoxy-5' fluorocytidine in the liver by carboxyl esterase, followed by cytidine removal from liver and tumor tissues. The action of the aminoase is converted to 5'-deoxy-5' fluorouridine and finally catalyzed by thymidine phosphorylase to fluorouracil (5-FU) in tumor tissues.
Clinical studies have shown that the concentration of 5-FU in tumor tissue after oral administration is significantly higher than that of blood and muscle. The efficacy of tumors in a variety of animals was significantly higher than 5-FU. This product has synergistic effects with a variety of anti-tumor drugs.

Function:
Capecitabine is an orally-administered chemotherapeutic agent used in the treatment of metastatic breast and colorectal cancers. Capecitabine is a prodrug, that is enzymatically converted to 5-fluorouracil in the tumor, where it inhibits DNA synthesis and slows growth of tumor tissue.
