The last time that I checked up on this subject the outcome was as follows: 1/ Dopamine patches would not work, because the Dopamine would be attacked and destroyed before it could travel from the patch to the brain. 2/ A levodopa patch would take care of the destruction while the chemical was in transit, but there is another factor which over-rides points 1 and 2. That is: 3/ Levodopa and Dopamine are such large molecules, and we need it in such large quantities, that I doubt if you could could get the flow rate required even if you used a full body patch!! (What an apalling thought) 4/ I think you will find, it you scan the press releases which have been issued from time to time the magic word 'agonist' lurking quietly in the release. I can't help wondering what is the point of a Dopamine Agonist patch, when the dopamine agonist tablets have such a long half-life that in the case of Cabergoline for instance you only take one per day anyway!!
