Overall Study
A randomised, double-blind, 2-way crossover design, followed by a period for assessment of adhesive properties of the clonidine patch. In the crossover part of the trial, subjects were treated with either Catapres®-TTS delivering 0.3 mg clonidine/24 h (TTS-3) in the Oppanol® formulation (test treatment T1) or Catapres®-TTS-3 (0.3 mg/24 h) with Vistanex™ formulation (reference treatment R1) in each period. In the adhesion phase of the trial, subjects were treated simultaneously with Oppanol® (test treatment T2) and Vistanex™ (reference treatment R2) patches, each delivering 0.1 mg clonidine/24 h (TTS-1).
