  • Solid pharmaceutical composition comprising (R)-(?)-2-[5-(4-fluorophenyl)-3-pyridylmethylaminomethyl]chroman
    Patent number: 8093270
    Abstract: The invention relates to a solid pharmaceutical preparation containing (R)-(?)-2-[5-(4-fluorophenyl-3-pyridylmethylaminomethyl]chroman as an active substance and at least one sugar alcohol (e.g. mannitol, sorbitol) as a filler. Also disclosed is the production of said solid pharmaceutical preparation, which is provided with an increased shelf life also at elevated temperatures and can be used for the treatment of dyskinesia associated with Parkinson's disease.
