Levodopa (L-dopa). A substance used in the treatment of Parkinson's disease. Levodopa can cross the blood-brain barrier that protects the brain. Once in the brain, it is converted to dopamine and thus can replace the dopamine lost in Parkinson's disease.
Dopamine Drugs and Possible Side Effects. Levodopa and the dopamine agonists (e.g., ropinirole, pramipexole, rotigotine), though proven to be very effective agents for managing RLS, may lead to the development of three common problems when used chronically: augmentation, compulsive behavior and sleepiness. With augmentation the brain becomes more and more dependent on these dopamine drugs. 2  The brain does not see âropiniroleâ or âpramipexoleâ, it see these drugs as just more dopamine in the system. 3  Essentially over time the brain, seeing all this extra dopamine, decides it does not need to make as much.
