Mechanism of action

Capecitabine is an oral fluoropyrimidine carbamate that undergoes hepatic and cellular enzymatic conversion to its active form, fluorouracil (5-FU). Once activated, 5-FU inhibits thymidylate synthase, blocking the synthesis of thymidylate and disrupting DNA replication in cancer cells. It also incorporates into RNA, further disrupting cellular function. The preferential activation in tumor tissue provides some selectivity for cancer cells over normal cells.
