In that I make the same points that you raised (although I confess that although I tried them back-to-back, I couldn't distinguish any difference in response. The faster response on the journey from mouth to brain I certainly did notice, and since then I have always used Madopar. I can confirm that Madopar is not available in the USA, nor is there a soluble form of Sinemet. (I suspect that it was a deal between the drug companies). There is one other aspect which favours Madopar a little, and that is the adverse effect of too much Carbidopa:- PWPs on high levels of Sinemet are advised to use the Sinemet 10/100 formulation to keep their intake of Carbidopa within certain limits, e.g. between 75 and 300 mg/day. It is not critical, but can cause some unpleasant effects above 300mg. Madopar, with Benserazide does not seem to have this problem.
