Primary Outcome Measures:
  • 7-day bowel diary, proportion of incontinent bowel movements [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 80
Study Start Date: July 2008
Study Completion Date: December 2013
Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Arm 1
Fiber (psyllium) powder
Drug: Psyllium powder
2 teaspoons with 8 ounces of liquid daily for 28 days (weekly adjusted dose)
Other Name: Metamucil
Active Comparator: Arm 2
Drug: Loperamide
1 capsule daily for 28 days (weekly adjusted dose)

Detailed Description:

Fecal incontinence (FI) affects 4-24% adults in the community and greatly impacts quality of life. Both fiber and loperamide are common, first-line treatments for diarrhea-associated FI in primary care. No known studies exist that compare fiber and loperamide for diarrhea-predominant FI. Further knowledge is needed to define which treatment is more effective and to compare drug tolerability (side effects) for FI. This study will also look at changes in quality of life with treatment and potential mechanisms of drug treatment.
