  Purpose

This study will test the hypothesis that GW427353, a beta-3 adrenergic agonist, retards the emptying of the colon and increases total colonic transit time.

Irritable Bowel Syndrome (IBS)
 Drug: Placebo
Drug: Solabegron (GW427353)
 Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Pharmacokinetics/Dynamics Study
Intervention Model: Parallel Assignment
