Health Clinical Trial
Official title:
Effects of Tolterodine, a Non-Specific Muscarinic Antagonist, on Gastrointestinal Transit in Healthy Subjects
The muscarinic antagonist tolterodine is widely used treat urinary urge incontinence. Though acteylcholine is the primary excitatory neurotransmitter in the gastrointestinal tract, the phase III trials suggest that tolterodine infrequently causes constipation. Therefore, the objectives of this study are to assess if tolterodine affects the speed at which food travels through the stomach, intestines and colon (i.e., gastrointestinal and colonic transit) in healthy subjects.
The specific aims of this study are to test the hypotheses that the non-specific muscarinic antagonist tolterodine will not:- i) delay colonic transit and the proximal colonic emptying rate; ii) delay gastric emptying; nor iii) delay small intestinal transit compared to placebo in healthy subjects. ;
