Sumanirole Maleate is primarily used in the treatment of Parkinson's disease. It functions as a dopamine agonist, stimulating dopamine receptors in the brain to improve motor control and reduce symptoms such as tremors, stiffness, and slow movement. This compound is particularly beneficial for patients who experience fluctuations in their response to other Parkinson's medications, offering a more stable therapeutic effect. Additionally, it is sometimes explored for its potential in managing restless legs syndrome due to its dopaminergic activity. Its selective action on dopamine receptors helps minimize side effects compared to non-selective agonists, making it a valuable option in neurological therapies.
