title: Rotigotine transdermal patch in combination therapy for Parkinson's disease--observations in routine clinical practice.
abstract: OBJECTIVE
  The dopamine agonist rotigotine has shown efficacy and safety for the treatment of early and advanced Parkinson's disease (PD) in controlled clinical trials. This observational study evaluated rotigotine administration in combination with other antiparkinsonian medication in routine clinical practice.
  
  
  METHODS
  Data were collected by 688 German practice-based neurologists, initiating rotigotine treatment in patients with idiopathic Parkinson's disease. Assessments included rotigotine maintenance dose, changes in concomitant PD medication, changes in sleep quality, and rotigotine tolerability over an observation period of 12-16 weeks.
  
  
  RESULTS
  The median rotigotine maintenance dose was 6 mg/24 h (n = 969, full analysis set). The proportion of all other prescribed PD medications declined over the observation period; combination therapy decreased by 18.7%. Daily levodopa intake was markedly reduced by 87 mg (18.9%) in 47.6% of the patients with levodopa documentation; 7% no longer required levodopa after 12-16 weeks. Mean overall sleep quality (PD Sleep Scale item 1) improved by 21.4 points, the occurrence of nocturias (PDSS item 8) by 13.4 points, and 'turning in bed' (Unified Parkinson's Disease Rating Scale part II) by 0.6 points. Drug-related adverse events were reported for 7.9% of all patients (n = 1152, safety population). Application site reactions were the most common adverse events (2.2%) resulting in early discontinuation in 1.4% of patients.
  
  
  CONCLUSIONS
  In routine clinical practice, treatment initiation with rotigotine transdermal patch was associated with a reduction of other prescribed PD medications and with an improvement of self-reported sleep quality.
