Pergolide mesylate is a synthetic ergoline with dopamine agonist properties. The endocrine profile was studied in a double blind crossover design in six normal males. Circulating PRL, TSH, GH, LH, FSH, and cortisol were measured in the basal state and after TRH (500 micrograms iv) administration at 4.5, 11.5, and 23.5 h after placebo or pergolide (100 micrograms orally). Pergolide caused suppression of basal PRL from 2-8 ng/ml to less than 2 ng/ml commencing 60 min after administration and persisting throughout the 23.5-h study period. For the three TRH tests, a suppression of peak PRL (mean +/- SEM) response to TRH of 54.6 +/- 5.1 vs. 1.9 +/- 0.5, 45.2 +/- 4.1 vs. 4.5 +2- 0.6, and 34.4 +/- 2.9 vs. 6.9 +/- 1.4 ng/ml, respectively, for placebo and pergolide was noted. Basal TSH levels were unaffected by pergolide, but after pergolide the peak TSH response to the first two TRH challenges was blunted (placebo vs. pergolide: 12.3 +/- 1.2 vs. 6.8 +/- 1.0 and 14.8 +/- 2.0 vs. 9.6 +/- 1.0, respectively); however, the third TSH response (9.8 +/- 1.1 vs. 9.3 +/- 1.2) was not blunted after pergolide. GH secretion was stimulated by pergolide with a consistent pulse observed within 60 min of pergolide administration and an enhancement in the number and amplitude of subsequent GH pulses throughout the 24-h period. Cortisol levels rose after pergolide and returned to levels seen on the control day at 16.5 h. FSH levels were unaffected but LH levels were lowered pergolide. Side effects including nausea, vomiting, and hypotension were observed in all subjects. Pergolide is a potent dopamine agonist with the anticipated endocrine profile and clinical effects; its long duration of actions offers promise of single daily dose therapy for hyperprolactinemia.

Fifteen Thai patients with Parkinson's disease (7 females, 8 males) were enrolled in an open label trial of pergolide (a new dopamine agonist) to evaluate its safety and efficacy. Inpatients and outpatients from Siriraj Hospital, Mahidol University, Bangkok 10700, Thailand from 1992 to 1994 were included in the study with a total duration of 18 weeks. Both de novo patients and patients who were being treated with levodopa without dopamine agonist and were obtaining a less than optimal response at both visit 1 and visit 2 were all enrolled in this study. At entry into the study, 3 patients had Hoehn and Yahr stage I, 7 patients at stage II, 3 patients at stage III, and 2 patients at stage IV. Pergolide dosage was gradually built up until an optimal dosage was achieved. The average dose of pergolide during the study was 0.94 mg/day (range 0.075 to 8 mg/day). All patients completed the study and no patients dropped out. Two patients (13.33 per cent) experienced nausea (on 0.4 mg/day and 0.075 mg/day), two patients (13.33 per cent) experienced sleepiness (0.50 mg/day and 0.075 mg/day) and one patient (6.67 per cent) unsteadiness on walking (0.50 mg/day). There was one patient who required pergolide up to 8 mg/day which is higher than the recommended dosage (5 mg/day) but this patient experienced no adverse effects and his disabled dyskinesic was abolished. Our study demonstrated the good toleration and efficacy of pergolide treatment for Thai patients with Parkinson's disease. This new dopamine agonist stimulates both D1 and D2 receptors in comparison to other dopamine agonists (bromocriptine and lisuride) which stimulate only D2 receptors.

In the past 15 years, clinical data of over 1,500 patients treated with pergolide mesylate have been published. Pergolide is a dopamine agonist with a potent stimulating effect on D2 and also on D1 receptors. This pharmacodynamic characteristic seems the most effective in increasing the motility in Parkinson's disease. Pergolide has been used almost exclusively as an adjunct to levodopa treatment. Its positive effects seems to be related to its long plasma half life, about 27 hours, and 5-6 hours of clinical activity; it has shown to be effective on all parkinsonian symptoms except for the reduction of postural reflexes, it reduces off periods and compared to bromocriptine, it considerably improves the activities of daily living. Adverse reactions are, for the most part, mild and reversible, they mostly include nausea and gastroenteric disturbances.

Twenty patients with problematic restless legs syndrome (RLS) were treated with pergolide. Efficacy, dosage, side effects, and tolerance were analyzed. Fifteen patients continued treatment for a median study time of 2 years. Five patients discontinued treatment after a mean of 4.2 months. Pergolide resulted in complete or near complete control of symptoms in 45% and moderate control in 50% of patients studied. Levodopa-induced daytime augmentation resolved in all patients in whom it had been present. The mean total daily maintenance dose of pergolide was 0.23 mg. Forty percent required an additional afternoon dose. Side effects developed in 12 patients (60%) and necessitated discontinuation of treatment in five. Common side effects were nausea, dizziness, and insomnia. Daytime augmentation occurred in 27% of patients, but this was mild and usually easily controlled with a supplementary afternoon dose of pergolide. Tolerance did not develop. We conclude that pergolide is an effective second-line agent for RLS, especially following levodopa-induced daytime augmentation.

The restless legs syndrome (RLS) characteristically presents with an irresistible urge to move that is most often accompanied by creeping sensations deep in the limbs. Occasionally the upper limbs can also be affected. RLS symptoms occur at rest and are typically more intense at night and at bedtime. Some patients complain about involuntary leg movements, so-called periodic limb movements (PLM), while at rest or PLM have been observed by the bed partner. Often, patients have to get out of bed several times at night, to relieve themselves of their disagreeable sensations.The prevalence of RLS is estimated to be about 5%. Up to now only three classes of drugs have been systematically evaluated for treatment of RLS: benzodiazepines, opioids and dopaminergic agents.The most consistent results have been obtained with dopaminergic drugs. Several studies have shown that L-dopa given with a peripheral decarboxylase inhibitor at a 10:4 ratio is effective in treating RLS. Controlled studies using polysomnographic recordings in a double-blind design showed that L-dopa administered at night produces a significant reduction of RLS occurring at bedtime and of PLM, which are often associated with nocturnal arousals. In most cases, L-dopa 100mg, in conjunction with the decarboxylase inhibitor carbidopa or benserazide 25mg, suppresses RLS although a rebound of PLM may be observed in the last part of the night. The two major adverse effects frequently seen in patients treated with L-dopa are:Augmentation is one of the limiting factors of L-dopa therapy; thus, alternative treatment options are of major interest. In several open treatment trials performed with pergolide, patients reported a marked improvement of RLS symptoms including sleep problems. Mild symptoms of augmentation under pergolide treatment have been reported from single patients. In another 6-month open label trial, pergolide proved to be effective in patients who developed augmentation under L-dopa by relieving daytime symptoms after switching to pergolide.Most recently, the results of these open label trials have been replicated in a randomized, placebo-controlled, double-blind multicenter trial. Treatment with a single evening dose of 0.25-0.75mg pergolide resulted in a significant improvement of almost all subjective and objective parameters. Under pergolide, patients rated their RLS symptoms and sleep disturbances much less severe and polysomnographic recordings also revealed a significant improvement of all important sleep parameters. To prevent peripheral side-effects such as nausea or orthostatic hypotension, pergolide should be slowly up-titrated or domperidone should be added. Under these conditions, no major side-effects have been observed in treatment trials with pergolide in dosages up to 1.25mg.Pergolide with a half-life of 12-16h thus appears to be an appropriate drug in the therapy of RLS especially in those patients who developed augmentation under L-dopa therapy. Owing to the remarkable therapeutic effect of pergolide on RLS symptom control, other dopamine agonists are presently being tested for the treatment of RLS.

The objective of this study is to determine whether pergolide therapy is an effective modality for the de novo treatment of patients with macroprolactinomas. Twenty-two consecutive patients with macroprolactinomas were included in the study and followed prospectively. These included 16 men and 6 women in whom pregnancy was not of concern. Pergolide was administered once or twice a day depending on the patient's preference. Ten patients received 0.1 mg daily as a maintenance regimen and in the others the daily dose ranged from 0.05 to 0.5 mg. Eight patients reported minor but tolerable side effects. One patient had to be switched to cabergoline because of intolerable nausea. After a mean of 12 months (range, 3-36), mean PRL levels declined from 3,135 ng/ml (range, 126-31,513) to 50 ng/ml (3-573), representing a mean PRL suppression of 88% (range, 0-99). PRL levels became normal in 15 patients and decreased to 25-40 ng/ml in 3 others. The mean tumor volume shrinkage was 25% or greater in 19 patients (86%), 50% or greater in 17 patients (77%), and 75% or greater in 10 patients (45%). Visual abnormalities were reversible after pergolide therapy in all but 1 of 12 patients with initially abnormal formal visual testing. Two out of 4 premenopausal women did not normalize PRL levels and had persistent oligomenorrhea. Testosterone was low in 14 men at presentation and normalized in 3 with pergolide therapy. We conclude that pergolide is a safe, inexpensive, and generally well-tolerated dopamine agonist for the treatment of macroprolactinomas in men and women in whom pregnancy is not of concern. In these specific populations, pergolide may become the first-line therapy for treatment of macroprolactinomas.

Tremor is one of the cardinal signs of Parkinson's disease (PD) but its response to antiparkinsonian medication is variable. It has been postulated that pramipexole may have a stronger antiparkinsonian tremor effect than pergolide, another direct acting dopamine agonist medication, possibly because the former has preferential affinity for the dopamine D3 receptor. The purpose of this pilot study was to compare the effects of a single oral dose of either pramipexole (Pr) or pergolide (Pe) or placebo (Pl) on parkinsonian tremor and the motor (part III) subsection of the UPDRS. Ten patients (6 men, 4 women), mean age 65.3 years, mean duration from diagnosis of 2.6 years, with tremor dominant PD were recruited. On three separate occasions a single dose of pramipexole (salt) 500 microg, pergolide 500 microg or placebo were administered in random order to each patient, who were pretreated with domperidone and had their antiparkinsonian medication withheld from midnight before study. After each medication patients were assessed at baseline and then every 30 min for 4 hr using a 0 to 10 tremor rating scale and the UPDRS (part III) in a double-blind protocol. Adverse effects were systematically recorded. The results demonstrate that 500 microg of either pramipexole or pergolide reduced PD rest tremor scores to a similar degree, which at peak effect was significantly greater than placebo (respectively Pe v Pl: P < 0.006, Pr v Pl: P < 0.033). The two active drugs also had weaker beneficial effects on the UPDRS part III. Pergolide, however, was significantly more likely than pramipexole to cause nausea (P = 0.005) or vomiting (P = 0.014).
