Primary Outcome Measures:
- To assess whether multiple dose administration of esreboxetine has the potential to affect QTc in healthy volunteers [ Time Frame: Up to 24 hours ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- To asses the the relationship between plasma concentrations of esreboxetine and its effects, if any on the QTc interval [ Time Frame: Up to 24 hours ] [ Designated as safety issue: Yes ]
- To assess the effects of a positive control (moxifloxacin) on QTc interval in healthy volunteers [ Time Frame: Up to 24 hours ] [ Designated as safety issue: Yes ]
