Apologies, where I come from this is not a common treatment for ADHD. I’m not a specialist but as a father of two lively boys I did my share of reading about diagnosing and treating ADHD in Europe.
Ritalin is the dominant drug in that regard, and while it is very similar in every respect, it is not amphetamine-the-substance nor, I believe, technically in the class of substances also referred to as amphetamines.
(someone stated that amphetamines are now available in the EU market. But, if so, it's likely that few people will know, mostly because discussions of ADHD have somewhat faded)
