title: Efficacy of rasagiline for the treatment of Parkinson's disease: an updated meta-analysis.
abstract: Rasagiline is a second-generation potent selective inhibitor of monoamine oxidase-B. The aim of the study was to analyze the effectiveness of rasagiline in treatment of Parkinson's disease (PD), both as monotherapy and combination therapy.
  
  
  
  Medline, Cochrane, EMBASE, and Google Scholar databases were searched until 9 March 2016 using the keywords: Rasagiline, Azilect, Parkinson's disease. Randomized controlled trials of patients with PD who were randomized to treatment with rasagiline or placebo were included. Outcomes were unified Parkinson's disease rating scale (UPDRS) and the three subscales.
  
  
  
  Ten studies fulfilled the inclusion criteria and 2709 patients were evaluated. The overall analysis revealed a significant improvement in change of total UPDRS scores in 1 mg/day and 2 mg/day rasagiline groups compared to placebo. Significant improvement in Part I (Mentation) of UPDRS scores was observed in 1 mg/day, but not in 2 mg/day rasagiline treatment group. Part II (ADL) and Part III (Motor) subscales significantly improved with both doses of rasagiline. Both monotherapy and combination therapy significantly improved total UPDRS scores.
  
  
  
  Our results confirm the efficacy of rasagiline in PD. Further studies are required to establish the optimal dose of rasagiline, as well as to determine its effectiveness in different combination therapy protocols. KEY MESSAGES Rasagiline treatment was associated with significant improvement of UPDRS scores and the scores of the subscales. Both monotherapy and combination therapy significantly improved total UPDRS scores. Effect of rasagiline on total UPDRS scores was not dose-dependent.
