Istradefylline, sold under the brand name Nourianz, is a medication used with levodopa/carbidopa for "off" episodes in Parkinson's disease (PD).[4][6] An "off" episode is a time when other medications are not working well, resulting in tremor and difficulty walking.[4] It is taken by mouth.[4]

Common side effects include involuntary muscle movements, constipation, hallucinations, dizziness, nausea, and trouble sleeping.[4] Other side effects may include compulsive behavior.[4] It is a adenosine A2A receptor antagonist.[2]

Istradefylline was approved for medical use in the United States in 2019.[5] In Europe it was refused approval in 2021 due to unclear evidence of benefit.[2] It is not available in the United Kingdom.[1] In the United States it costs about 1,500 USD per month.[7]
