Description

uridine triacetate: A uridine prodrug that is used in the treatment of hereditary orotic aciduria. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

uridine triacetate : An acetate ester that is uracil in which the three hydroxy hydrogens are replaced by acetate group. A prodrug for uridine, it is used for the treatment of hereditary orotic aciduria and for management of fluorouracil toxicity.
