Clinical Trial Controlled Clinical TrialLow-dose bromocriptine in the early phases of Parkinson's disease.
The effect of bromocriptine at doses up to 20 mg/day was studied in a single-blind format with a placebo phase in 15 Parkinson's disease patients with mild-to-moderate disability who had not been previously treated with levodopa. For the 11 patients who completed the 9 month trial, both Northwestern University Disability Scale and Columbia University Rating Scale scores were significantly reduced during bromocriptine therapy, when compared with either baseline or placebo scores. ⋯ Transient side effects appeared in four patients. Bromocriptine at doses of 20 mg/day or below may yield effective symptomatic improvement in de novo parkinsonism and may be considered as the initial treatment in young parkinsonian patients with only mild-to-moderate disability.
