The non-ergot dopamine agonist pramipexole is currently indicated for the treatment of the signs and symptoms of idiopathic Parkinsons disease and for the treatment of moderate-to-severe primary restless legs syndrome. A new extended-release formulation of pramipexole has now also been launched in Europe and the US to improve ease of use, compliance and provide a more continuous therapeutic effect over 24 hours. Before initiating any treatment, the benefit-risk ratio to the individual patient must be considered. For pramipexole in the treatment of Parkinsons disease, this means taking into account the available evidence regarding its symptomatic efficacy, effect on delaying long-term levodopa-related motor complications, beneficial effect on non-motor symptoms such as depression, and its safety and tolerability profile. Studies have shown that pramipexole is effective as monotherapy in early Parkinsons disease and as adjunctive therapy in advanced disease. Trials further suggest that the benefits of pramipexole may extend beyond the relief of motor symptoms (akinesia, rigidity and tremor at rest) to the amelioration of depressive symptoms in Parkinsons disease. Pramipexole is generally well tolerated; however, compared with levodopa treatment, pramipexole is associated with a higher rate of some dopaminergic adverse effects.
