The therapeutic effectiveness of a L-DOPA preparation of sustained action was established in 9 patients with parkinsonism on the basis of a neurological parkinsonism scale and Northwestern University Disability Scale. The investigations were carried out by the method of cross test with conventional L-DOPA preparation (Larodopa). In these investigations no higher effectiveness of the retard form was shown. Side effects during administration of the retard form were more frequent and more intense than during administration of the conventional drug.
