Trifluridine/tipiracil (FTD–TPI), sold under the brand name Lonsurf, is a fixed-dose combination medication that is used as a third- or fourth-line treatment of metastatic colorectal cancer or gastric cancer, after chemotherapy and targeted therapeutics have failed.[5][6] It is a combination of two active pharmaceutical ingredients: trifluridine, a nucleoside analog, and tipiracil, a thymidine phosphorylase inhibitor.[5][6] Tipiracil prevents rapid metabolism of trifluridine, increasing the bioavailability of trifluridine.[4]
The most common side effects include neutropenia (low levels of neutrophils, a type of white blood cell that fights infection), feeling sick, tiredness and anemia (low red blood cell counts).[4][5][6]
