Further study details as provided by Novartis:

Primary Outcome Measures:
  • To determine if tegaserod 6 mg b.i.d modulates gastric sensitivity to mechanical distention of the stomach

Secondary Outcome Measures:
  • 1) Comparing effects at end of treatment compared to baseline:
  • To verify that tegaserod modulates esophageal sensitivity to esophageal distention
  • To determine if tegaserod improves individual dyspeptic symptoms of epigastric pain/discomfort
  • To determine if tegaserod improves heartburn and/or regurgitation
  • To determine if tegaserod is preferred by patients with functional heartburn & accompanying dyspepsia & gastric mechanical sensitivity over placebo
  • Safety assessment
  • To determine if there is a correlation between esophageal & gastric mechanosensitivity thresholds in this patient group, and to determine if tegaserod alters this relationshi
