Randomized, double‐blind study of pramipexole with placebo and bromocriptine in advanced Parkinson's disease

Abstract
We compared the efficacy and safety of pramipexole (PPX) with placebo in the treatment of advanced Parkinson's disease (PD) as an adjunct to levodopa. A bromocriptine (BR) group was included to enable determination of the noninferiority of PPX relative to BR as the standard treatment. © 2003 Movement Disorder Society
