Uridine triacetate

Uridine triacetate (INN),^[1] formerly known as vistonuridine, is an orally active tri-acetylated prodrug of uridine^[2] used:

• in the treatment of hereditary orotic aciduria (brand name Xuriden /ˈzʊərədɛn/ ZOOR-ə-den);^[3]
• to treat people following an overdose of chemotherapy drugs 5-fluorouracil (5-FU) or capecitabine regardless of the presence of symptoms, or who exhibit early-onset, severe or life-threatening toxicity affecting the cardiac or central nervous system, and/or early-onset, unusually severe adverse reactions (e.g., gastrointestinal toxicity and/or neutropenia) within 96 hours following the end of fluorouracil or capecitabine administration (brand name Vistogard).^{[4][5][6][7][8]}
