A Placebo-Controlled Study of Clonidine for Fecal Incontinence.

Completed · Phase 2 · Has a placebo group

Conditions studied: Fecal Incontinence

In brief

Fecal incontinence is the involuntary leakage of stool from the anus. Doctors at Mayo Clinic are doing a research study to assess the effects of a medication, clonidine, on fecal incontinence and rectal functions in women. Clonidine has been approved by the Food and Drug Administration (FDA) for treating high blood pressure, but not for treating incontinence and rectal functions. The hypothesis of this study is clonidine will improve fecal incontinence, increase rectal capacity and reduce rectal sensation to a greater extent than placebo in women.
