I think there is some real promise here, but if you're a drug company and the FDA tells you that they are interested in drugs for the disease, that's great and all, but where do you start? You might put forward some drugs that might eleviate some symptoms like fatigue, but other that you probably don't know where to start.
Maybe we ask the FDA to review existing research on ME/CFS where medications were used. As an example - and that's all this is, as its something I happen to have been looking at recently - the arsenic derived drugs used by Dr Tarello some time ago.
I expect there are several medications that have been used in small research which showed promise but which then didn't get followed up...one of the reason why being that there was so little interest before.
It seems to me that there may be drugs out there that have already shown some potential benefit for some ME/CFS patients, so if the FDA looked at those and engaged with the manufacuters of those drugs then proper trials might actually happen, and maybe one of them would work out.
