PHARMACHOLOGIC EFFECT
Antitumor agent.
It has a selective cytotoxic effect. In tumor tissue, capecitabine is converted to 5-fluorouracil by thymidine phosphorylase (tumor angiogenic factor).Thymidine phosphorylase activity in the primary tumor is 4 times higher than in healthy tissue, so the concentration of 5-fluorouracil in tumor tissue is higher than in healthy tissue and in plasma.
In both healthy and tumor cells, 5-fluorouracil is metabolized to form 5-fluoro-2-deoxyuridine monophosphate and 5-fluorouridine tri-phosphate, which have a cytotoxic effect.
