Effects of Tolterodine, a Non-Specific Muscarinic Antagonist, on Gastrointestinal Transit in Healthy Subjects - Full Text View

ClinicalTrials.gov Identifier:	NCT00332137

Purpose

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.

Primary Outcome Measures:

Colonic transit (as measured by GC24)

Secondary Outcome Measures:

Colonic transit (GC48)
Ascending colon emptying t1/2
Colonic filling at 6 hours, i.e. a surrogate marker of small bowel transit time
Gastric emptying time (1, 2, 4 hours, thalf)
Average number of stools per day before and during treatment

Estimated Enrollment:	36
Study Start Date:	September 2005
Study Completion Date:	August 2007
Primary Completion Date:	August 2007 (Final data collection date for primary outcome measure)

Detailed Description:

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.
