Non-ergot dopamine agonists have become popular for treating motor complications associated with long-term use of levodopa-containing drugs. We conducted a retrospective study in which we identified clinical problems related to use of non-ergot dopamine agonists. The study included 38 patients with Parkinson’s disease (PD) who suffered the wearing-off phenomenon and had thus been under non-ergot dopamine receptor agonist therapy for 1 - 2 years. Some presented with problems such as major symptoms of PD (30.3%), psychiatric symptoms (24.2%), and postural dysfunction (21.2%). Comparison between two different non-ergot drugs showed the levodopa dosage to be greater among patients taking ropinirole than among those taking pramipexole. In patients with advanced PD, various problematic symptoms can develop early after administration of a non-ergot dopamine agonist to treat the wearing-off phenomenon, necessitating identification and treatment of such symptoms on a patient-to-patient basis.
