GENERIC NAME: pramipexole
BRAND NAME: Mirapex, Mirapex ER
DRUG CLASS AND MECHANISM: Pramipexole (Mirapex) is used for the treatment of Parkinson's disease (PD) and restless leg syndrome (RLS). Pramipexole stimulates dopamine receptors in the brain. The exact mechanism of action of pramipexole in Parkinson's disease is unknown. However, treatment benefits are thought to be related to the stimulation of dopamine receptors in the area of the brain known as the striatum. Pramipexole may improve movement performance and activities of daily living in patients usually within 2-3 weeks of starting treatment. The exact mechanism of action of pramipexole for the treatment of RLS is unknown. Benefits of treatment are thought to be associated with stimulating dopamine receptors in the brain.
