Abstract
Lisuride, a semisynthetic ergoline and potent central dopamine and serotinin agonist, was combined with levodopa in 20 patients with advanced Parkinson disease who were no longer responding satisfactorily to levodopa, including 14 patients with “on-off” phenomena. Every patient who completed the week trial improved significantly (p <0.01), with a decrease in all symptoms. The mean dose of lisuride was 2.4 mg per day. The dose of levodopa (mg of levodopa in Sinemet) was reduced from 1030 to 920 mg. Among the patients with “on-off” phenomena, there was a significant increase in the time in which they were “on” (mobile) from 4.6 to 9.6 hours. In 5 of 10 patients who have been on lisuride for at least 1 year, there has been no decline in efficacy.
