A medical cure for stuttering will most likely come from off label use of another drug or finding out a research drug has other uses like they found in Viagra. Viagra was intended to be a blood pressure medication until they found out it has another use. Another problem is we don't know the exact mechanism behind stuttering making it nearly impossible to target. My guess is it won't be a single pill treatment. It will be a stack of multiple drugs to attack it through multiple mechanisms.
