Product Description
Istradefylline is used along with the combination of levodopa and carbidopa (Duopa, Rytary, Sinemet, others) to treat "off" episodes (times of difficulty moving, walking, and speaking that may happen as medication wears off or at random) in people with Parkinson's disease (PD; a disorder of the nervous system that causes difficulties with movement, muscle control, and balance). Istradefylline is in a class of medications called adenosine receptor antagonists. It works by changing the activity of certain natural substances in the brain.
