[The study on the assessment of the new levodopa drug--stalevo (levodopa/carbidopa/entacapone), in treatment of Parkinson's disease in out-patient clinical practice (the results of the open START-M)].
Despite significant symptomatic effect of levodopa, in most patients the stable 24 hour's effect changed for alterations of movement symptoms (fluctuations, dyskinesia) after 2-3 years of the therapy. These complications may be reduced due to the constant (physiologic) stimulation of post-synaptic dopamine receptors that, to a certain degree, provides the drug stalevo, which contains levodopa and 2 enzyme inhibitors, dopa decarboxylase (carbidopa) and catechol-O-methyltransferase (entacapone). The results of the study demonstrated beneficial effects of stalevo as compared to traditional therapy in patients with "wearing off" and "on-off" phenomena.
