Hilary Blue wrote about her acceptance in a trial study of a new anti-dyskinesia drug- I can't be sure, but I suspect the unknown test drug will be one of several "atypical" antidepressants (e.g., olanzapine, quetiapine, etc.) which have been tried and rejected as substitute for clozapine, which does work but requires weekly blood test to avoid a rare but dangerous side effect. If you wish to dig deeper, there are numerous referenced items in the archives of this list, including several in my CSRs. Cheers, Joe -- J. R.
