New Treatment fr Dyskinesia?

The Michael J Fox web site has just reported that the FDA has approved a new treatment for dyskinsia - Amantadine extended release.Does anyone know if this is approved/available in the UK?

It's not in the latest BNF, so I don't think so. I don't think it's likely to appear any time soon, all the trials are American. I can't find any UK trials. As the dose is very variable anyway, from person to person I can't see the advantage. 

normal amantadine is in uk
