Antiparkinsonian activity of a non-ergot dopamine agonist, CV 205-502, in patients with fluctuating Parkinson's disease

Authors


Abstract

Six patients with fluctuating Parkinson's disease received single rising oral doses of the nonergot dopamine agonist CV 205-502 in an open experimental study. Doses of 0.5 mg produced antiparkinsonian effects of comparable intensity but longer duration than 200 mg of L-DOPA. CV 205-502, which combines structural features common to both ergolines and apomorphine, thus revealed interesting antiparkinsonian properties, but nausea and vomiting were dose-limiting side effects in all patients tested.
