Hello pdchick, and welcome to NeuroTalk.

As you're asking about PD medications, I wonder if you might get the information that you seek if you were to ask some of our members over in our Parkinson's Forum.

Here's a direct link to take you there, but please remember that advice given on this site should never take the place of medical advice from your own doctor.
