Drug success

[Greenleaf360]

Im looking for a study that records how many people find relief with which drug. There are 4 classes:
1) iron therapy. What percentage find relief of RLS symptoms through iron therapy.
2) gabapenting group
3) dopamine agonists
4) opioids

I am specifically interested in how many find long term relief from dopamine agonists without augmentation.

I don't believe that I have seen anything along those lines. There are bits and pieces of info in the literature, such as the success rate for iron IVs and gabapentin, but finding anything about dopamine agonists would be very challenging since they initially work for anyone who tries them and then there is the attrition rate due to augmentation and those that have to quit due to impulse control disorder.
As for opioids, there was a recent publication by Dr WInkleman at Mass General that is an interim report of the RLS Opioid Registry. You might find a bit of what you are interested in that paper because he lists the patients (like me) who use an opioid along with one of the others. So that might provide a bit of insight into what you are thinking about.
