Pergolide mesylate, a semisynthetic ergoline and a potent, long-acting central dopamine agonist, was tested in 13 patients with advanced Parkinson disease and diurnal oscillations in performance ("wearing-off" or "on-off" phenomena or both) whose response to levodopa had diminished considerably. Among all nine patients who completed the initial clinical(More)
Treatment with pergolide was compared with bromocriptine in 25 patients, all of whom were also receiving levodopa and in all of whom the response to levodopa had diminished. All 25 patients had "on-off" phenomena. At the time bromocriptine was added to levodopa, the mean age of the patients was 61.8 years, mean duration of disease was 9.0 years, and mean(More)
Data from 23 normal men and women were used to derive 95% confidence limits for maximum changes in ammonia and lactate values following ischemic forearm exercise. Most normal subjects raised serum lactate and ammonia concentrations more than 20 mg/dl and 100 micrograms/dl, respectively, over baseline values. No significant correlations were found among age,(More)
Lisuride, a semisynthetic ergoline and potent central dopamine and serotonin 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 8-week trial improved significantly (p greater than or equal(More)
Pergolide, a semisynthetic ergoline and a potent long-acting adenylcyclase-linked dopamine agonist, was given to 40 patients with advanced Parkinson's disease whose response to levodopa had diminished considerably. The group included 31 patients with marked diurnal oscillations in performance ("wearing off" and/or "on-off" phenomena). Pergolide alone (7(More)
