Used primarily in the treatment of Parkinson's disease, it helps to replenish dopamine levels in the brain, alleviating symptoms such as tremors, stiffness, and slowness of movement. It is also employed in managing Parkinsonism symptoms caused by carbon monoxide or manganese intoxication. Additionally, it is utilized in research studies to understand dopamine-related neurological processes and disorders. In some cases, it is used off-label to treat certain types of depression and restless legs syndrome due to its ability to influence dopamine pathways.
