Foscarbidopa/foslevodopa, sold under the brand name Vyalev among others, is a fixed-dose combination medication used for the treatment of Parkinson's disease.[2][5] It is a fixed-dose combination of foscarbidopa, an aromatic amino acid decarboxylation inhibitor and prodrug for carbidopa;[5] and foslevodopa, an aromatic amino acid and prodrug for levodopa that was developed by AbbVie.[5][6][7][8][9][10] Its structure is identical to carbidopa/levodopa except for the replacement of a hydroxyl on each molecule with a phosphate group, similar to the antiepileptic prodrug fosphenytoin as it relates to phenytoin.[citation needed]
The combination was refused approval by the US Food and Drug Administration (FDA) in 2023.[11] It was approved for medical use in Canada in May 2023,[4] in Australia in March 2024,[1] and in the United States in October 2024.[12][13]
Produodopa uses a pump to steadily release foscarbidopa/foslevodopa into the bloodstream round-the-clock. It is available via the UK National Health Service since February 2024.[14][15]
The combination of foscarbidopa and foslevodopa is indicated for the treatment of motor fluctuations in adults with advanced Parkinson's disease.[5]
The most common adverse reactions include infusion/catheter site reactions, infusion/catheter site infections, hallucinations, and dyskinesia.[5]
