Pergolide (Permax, LY127809, CAS 66104-23-2) a dopamine agonist for the treatment of Parkinson's disease, was evaluated for reproductive and developmental toxicity. Pergolide was administered in the diet at levels of 0, 5, 15, or 50 ppm to male and female ICR mice. In the F0 generation, the males were treated for 9 weeks prior to mating and throughout mating. The females were treated for 2 weeks prior to mating and throughout mating, gestation, and location (postnatal segment only). Females assigned to the teratology segment were killed on gestation day 18 for evaluation of fetal viability, weights, and morphology. Females assigned to the postnatal component were allowed to deliver and maintain their offspring throughout a 21-day lactation period. One male and one female were selected from each litter to continue as the F1 generation. Possible exposure of the F1 generation to pergolide ended at weaning. Growth of the F1 animals was monitored and reproductive performance evaluated. Treatment-related effects in the F0 generation were consistent with the pharmacologic effects of a dopamine agonist. These effects included pregnancy blockage at the 50-ppm dietary level and dose-related body weight depression in lactating dams and suckling progeny at the 15- and 50-ppm dietary levels. An increase in progeny mortality at the 50-ppm dietary level was attributed to lactation failure of the treated dams. The F1 mice of the 15- and 50-ppm groups remained smaller than the control mice until termination at approximately 20 weeks of age, although weight gains following weaning were not depressed and no impairment of mating performance or fertility was observed.(ABSTRACT TRUNCATED AT 250 WORDS)

An 8-month multicentre prospective randomized study aimed at comparing the effects of dopamine receptor agonists pramipexole (PPX; Mirapexin) and pergolide (PRG; Permax) as add-on to L-dopa therapy on depression [Montgomery and Asberg Depression Rating Scale (MADRS)] in 41 non-demented patients (25 men, 16 women) suffering from both mild or moderate depression and advanced Parkinson's disease (PD). The assessment was performed by a blinded independent observer. Motor symptoms (UPDRS III), motor complications (UPDRS IV), activities of daily living (UPDRS II and VI) and depressive symptoms as measured by Self - Rating Depression Scale by Zung were evaluated in an open-label design. The average value of Zung scores decreased significantly in both groups with no statistical difference between both groups. A significant decrease in the average value of MADRS scores was present only in the PPX group. The average UPDRS scores decreased significantly with no statistical difference between both groups at the comparable average total daily dose of both preparations. In both cases, the total daily dose of L-dopa decreased significantly but the decrease was statistically more pronounced in the PRG group. Our results demonstrate the antidepressant effect of PPX in patients with PD while we can't make any conclusions with regard to antidepressant effect of PRG.

One of the most disabling problems in males suffering from advanced Parkinson's disease (PD) is complex sexual dysfunction. The effect of dopamine replacement or dopaminergic stimulation on sexual dysfunction has been recently examined and described in patients treated by L-DOPA or apomorphine. Pergolide mesylate is another dopamine agonist with a known high affinity to hD(2S) subtype and a lower affinity to hD(2L) subtype of D2 dopaminergic receptors. It has been repeatedly shown to be a highly effective treatment of the complicated and advanced stages of PD. The current study has been designed to assess its efficacy in the treatment of sexual dysfunction, which frequently accompanies the complicated stage of PD in males. Fourteen male patients suffering from PD, each of whom had been treated with L-DOPA, and in whom additional treatment with peroral dopaminergic agonist (DA) was needed, were followed for a 6-month period. Pergolide mesylate (Permax) was given to each patient, and titrated to a total daily dose of 3 mg. All of the patients were taking L-DOPA. The assessments performed before the start of pergolide treatment consisted of a neurological examination, including Unified Parkinson's Disease Rating Scale (UPDRS) III and IV subscales scoring, Mini Mental State Examination (MMSE) scoring, the neuropsychological examination including Zung scale scoring to exclude depression, biochemical and haematological examinations including the examination of prolactine serum levels; and a sexological examination during which the patients filled-in the International Index of Erectile Function (IIEF) questionnaire. These examinations were repeated during the control assessments at months 1, 3 and 6. To compare the examination results, anova, Friedmann's anova (non-parametric) and Tukey post hoc tests were used. There were statistically significant differences between the values of UPDRS III motor subscale, UPDRS IV (complications of therapy) subscale and all subscales of IIEF when months 0 and 1 were compared with the results obtained at months 3 and 6. The differences between months 0 and 1 and months 3 and 6 (in these items) were virtually insignificant. In conclusion, pergolide substantially improved sexual function in the younger male patients who were still interested in sexual activities. In such cases, the introduction of pergolide might be a better choice than treatment with sildenafile, which usually meets several contraindications in common PD male population.
