Drug Function and Efficacy

Tegafur in TS-1 inhibits thymidylate synthase, preventing deoxyuridylic acid from converting to deoxythymidylic acid, thereby interfering with DNA synthesis. Gimostat in TS-1 inhibits fluorouracil-degrading enzymes in the gastrointestinal tract, thereby prolonging the duration of drug action. Oxonamide potassium in TS-1 is a gastric mucosal protective agent.

This ingredient has been used in drugs with the following functions (note: it does not mean that the ingredient itself has the following health functions)
