Overview

Tegafur + folinic acid is an oral combination chemotherapy regimen primarily used for the treatment of advanced or metastatic colorectal cancer. Tegafur is a prodrug that is converted in the body to fluorouracil (5-FU), a pyrimidine analogue that inhibits DNA synthesis by blocking thymidylate synthase. Folinic acid (also known as leucovorin or calcium folinate) enhances the cytotoxic effect of 5-FU by stabilizing its binding to thymidylate synthase, thereby increasing inhibition of DNA synthesis in tumor cells. This combination allows for effective oral administration and has demonstrated efficacy with acceptable toxicity profiles in clinical studies[2][3][6][7]. Folinic acid itself does not have direct anticancer activity but potentiates the effect of fluoropyrimidine drugs like tegafur.
