There is a clinical trial coming to the U.S. by Solvay that uses an intestinal pump for continuous l-dopa infusion. It's been used in Europe for quite a while. There have been difficulties working it out with the FDA. It will be a Phase III trial and the treatment is called Duodopa. FDA is insisting on a sham surgery trial.

I have heard "things" about inhalants, but not sure it's l-dopa and can't share it because i don't know any more than that. Competition is very stiff, and the researcher was not at liberty to discuss. I think it's pretty safe to say they are researching those possibilities. Researcher said he may have something to talk about later this year.
