Patient Education

Safinamide


Safinamide 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). Safinamide is in a group of medications called monoamine oxidase type B (MAO-B) inhibitors. It works by increasing the amount of dopamine (a natural substance that is needed to control movement) in the brain.
