Abstract
Three trials evaluated the efficacy and safety of pergolide.Eighty-six de novo patients and 314 patients already receiving levodopa were enrolled in an open-label study. Of the de novo patients, 47.5% showed a marked or moderate improvement and 32% showed a mild improvement. In the levodopa add-on group, 53.8% showed marked or moderate improvement and 36.3% showed mild improvement. In a short-term, double-blind study, the efficacy of pergolide was compared with that of bromocriptine. One hundred seventy-two patients were randomized to receive pergolide, and 173 were randomized to receive bromocriptine. In de novo patients, bromocriptine (n equals 49) and pergolide (n equals 49) demonstrated similar efficacy. However, significantly more levodopa-treated patients in the pergolide group, compared with the bromocriptine group, demonstrated marked or moderate improvements in several items of the rating scale score. In a long-term study, 151 of 314 patients receiving pergolide in combination with levodopa remained in the study for 3 years, and 127 for 4 years, and in these patients the initial improvement was maintained. In 18 of 62 de novo patients, the initial improvement was maintained for up to 3 years. These trials indicate that pergolide has efficacy in patients with Parkinson9s disease, either as monotherapy or in combination with levodopa. NEUROLOGY 1995;45(suppl 3): S13-S21
