How Does It Work?Neupro belongs to a group of medications known as dopamine agonists. This means that it works much like dopamine, a naturally occurring brain chemical. It binds to dopamine receptors and stimulates them, much like natural dopamine would.
Dopamine deficiency, which is caused by a loss of dopamine-producing cells in certain parts of the brain, may be responsible for many of the symptoms of Parkinson's disease. By using a medication that acts like dopamine, such as Neupro, some of the symptoms of Parkinson's disease may be relieved. Although it would make sense to give dopamine itself to treat Parkinson's disease, this does not work because dopamine cannot cross the blood-brain barrier to reach the brain. Neupro acts much like dopamine and is capable of crossing the blood-brain barrier, making it an ideal Parkinson's medication.
It is not exactly clear how Neupro works for treating RLS, although it is thought that the drug's effectiveness for treating RLS is due to its dopamine-agonist properties.
