Vistogard (uridine triacetate) works by slowing down cell damage caused by certain cancer medicines (fluorouracil or capecitabine). Uridine, from uridine triacetate, competitively inhibits cell damage and cell death caused by fluorouracil. Uridine triacetate is an acetylated pro-drug of uridine.

What does Vistogard treat?

  • Vistogard is used to treat an overdose of the cancer drugs capecitabine or fluorouracil (5-FU). It’s rare that an overdose of chemotherapy could occur, but toxicity can be fatal.
  • Vistogard is also used in patients who have emergent severe or life-threatening toxicities within four days of receiving capecitabine or fluorouracil. These side effects may include effects on the heart, nervous system, stomach, intestines, or blood cells.
  • It is not known if Vistogard is safe and effective if started more than 4 days (96 hours) after the end of a dose of fluorouracil or capecitabine.

In clinical studies in those treated for overdose or toxicity, 97% and 89% of patients, respectively, were still alive at 30 days.

The most common side effects that occurred in 2% or more of patients receiving Vistogard in clinical trials included vomiting, nausea, and diarrhea.
