Primary Outcome Measures:
  • To identify whether GW679769 has an effect on gastric accommodation to a meal, as measured by gastric barostat in male and female patients with FD. Meal induced fundus relaxation as measured by gastric barostat. [ Time Frame: Three to Five Days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Rate of gastric emptying as measured by dual breath test.Thresholds for perception and discomfort during gastric distension by gastric barostat. [ Time Frame: Three to Five days ] [ Designated as safety issue: No ]

Detailed Description:

An exploratory study to investigate the effects of the NK1 antagonist GW679769, 120 mg once daily for 4 days, on gastric accommodation, gastric emptying and gastric distension-induced perception and discomfort in adult male and female patients with functional dyspepsia, in a single-centre, placebo-controlled, double-blind, randomised, two-period crossover study

Such decision will be left to the Principal Investigator's discretion.
