Pramipexole
Pramipexole is a drug used to treat the symptoms of Parkinson's Disease (PD).  It is a non-ergot dopamine agonist drug that is efficacious in treating various Parkinson's symptoms such as tremor, rigidity, and bradykinesia (slow movement). It was first approved by the FDA in 1997. Parkinson's Disease is one of the most common neurodegenerative disorders and causes a high level of disability in patients, leading to increased difficulty in performing activities of daily living due to symptoms that progress over time. The prevalence of Parkinson's Disease worldwide has increased from approximately 2.5 million in 1990 to about 6.1 million in 2016.  This increase may be attributed to an aging population along with other contributing factors.  In addition to the above FDA approval for Parkinson's Disease, pramipexole was also approved by the FDA in 2006 for the treatment of Restless Legs Syndrome (RLS). RLS is a sleep-related disorder characterized by unpleasant sensations in the lower extremities, often accompanied by an uncontrollable urge to move the legs.
