Step-by-step explanation:
Pramipexole and Ropinirole are dopamine agonists used extensively in the treatment of Parkinson's disease. Parkinson's disease is a neurodegenerative disorder characterized by the loss of dopamine neurons in the substantia nigra, a midbrain structure that regulates movement. These drugs work by increasing dopamine levels in the brain, helping to alleviate the symptoms of Parkinson's disease.
