Used primarily in the treatment of Parkinson’s disease, especially for managing sudden episodes of immobility ("off" episodes). It acts as a dopamine agonist, stimulating dopamine receptors in the brain to improve motor function. Administered subcutaneously for rapid onset within a few minutes, with effects lasting approximately 40-60 minutes, it helps patients regain movement quickly and is suitable for emergency or temporary use. Also investigated for use in treating erectile dysfunction due to its action on central nervous system pathways, though this application is not yet widespread. Has been explored in research settings for potential anti-addictive properties and behavioral disorders.
