High compliance with rotigotine transdermal patch in the treatment of idiopathic Parkinson's disease.
OBJECTIVE
The non-ergot dopamine agonist rotigotine has been formulated in a once-daily transdermal patch for 24-h application which ensures continuous rotigotine release over 24 h. This open, prospective, non-interventional study investigated compliance with the patch under clinical practice conditions.


METHODS
Data were collected by German practice-based neurologists, prescribing rotigotine to patients with idiopathic Parkinson's disease; the observation period was 4 months. Following titration, 943 patients (mean age 67.6 +/- 9.3 years; 59% male) were maintained on rotigotine for at least 4 weeks (per-protocol population). At the end of the observation period, this patient population was assessed for various aspects of compliance using a 4-item Morisky scale ranging from 1 = least compliance to 4 = maximal compliance. Safety was evaluated in all 1099 patients receiving rotigotine treatment.


RESULTS
The mean satisfactory rotigotine dose of 5.4 +/- 1.6 mg/24 h was reached after 27 +/- 17 days; 84% of the patients did not require dose adjustments during maintenance. Complete compliance questionnaires were available for 863 patients (92%) who achieved a mean compliance sum score of 15.1 +/- 1.6 points out of the maximum 16 points. Mean scores of 3.6-3.9 points for the four scale items indicate that the patch was applied once-daily and at the appropriate time by the majority of the patients, independent of their clinical status. Skin reactions (3.7%) and known dopaminergic side-effects such as nausea (3.5%) were mostly mild or moderate in intensity.


CONCLUSIONS
Rotigotine transdermal patch was associated with high compliance in patients with Parkinson's disease under clinical practice conditions.
