Influence of Pramipexole on the QT Interval of the ECG in Healthy Male and Female Volunteers

Study Overview
=================
Brief Summary
-----------------
The objective of the study is to assess that pramipexole does not prolong the QT interval more than placebo

Official Title
-----------------
A Double-blind, Randomised, Placebo Controlled Study With Two Sequential Two-way Cross-over Parts to Demonstrate That the Influence of Pramipexole up to 4.5 mg Daily on the QT Interval of the ECG in Healthy Male and Female Volunteers is Comparable With Placebo, With a Positive Control (Two-way Cross-over Moxifloxacin Versus Placebo)

Conditions
-----------------
Healthy

Intervention / Treatment
-----------------
* Drug: Pramipexole extended-release (ER) tablets
* Drug: Pramipexole immediate-release (IR) tablets
* Drug: Moxifloxacin
* Drug: Pramipexole Placebo
* Drug: Moxifloxacin Placebo
