Abstract: Use of 2H-benzimidazol-2-one, 1,3-dihydro-1-(2{4-[-(trifluoromethyl)phenyl]-1-piperazinyl}ethyl)- or a physiologically acceptable acid addition salt thereof, for the manufacture of a medicament for the treatment of extrapyramidal movement disorders. These extrapyramidal movement disorders may result from idopathic Parkinson's disease, from the adverse effects of the administration of anti-Parkinson drugs in idiopathic Parkinson's disease, from dyskinesias caused by idiopathic Parkinson's disease and/or long-term administration of anti-Parkinson drugs, from Parkinson-like or Parkinson-related syndromes of from Parkinsonoid symptoms. Another aspect of the present invention concerns a pharmaceutical composition comprising, as active ingredients-(I) 2H-benzimidazol-2-one, 1,3-dihydro-1-(2-{4-[3-(trifluoromethyl)phenyl]-1-piperazinyl}ethyl)-or a physiologically acceptable acid addition salt thereof, and (II) at least one anti-Parkinson drug, in combination with one or more pharmaceutically acceptable excipients.
