Neupro (Rotigotine) is a dopaminergic agonist available in a skin patch. Many people benefited from Neupro in the past but it was taken off the market by the FDA when it was noted that some of the medicine crystalized on the patch and therefore did not get absorbed well through the skin.
A patch delivery of medicine allows more continuously absorption of medicine throughout the day. A small percentage of people cannot tolerate the patch experience skin irritation or rash. Side effects of dopaminergic agonists are still a concern for this patch especially impulsivity control problems, sedation, hallucinations, nausea, and low blood pressure.
