Study Arms:
- Therapeutic (Type: EXPERIMENTAL): 40 subjects with diarrhea-predominant IBS (IBS-D) or mixed IBS (IBS-M) will be enrolled in the study. At the first clinic visit, subjects will undergo rectal sensitivity testing, as well as lactulose breath testing. Subjects will be asked to record their symptoms and bowel habits in a diary over the next 7 days. During the second clinic visit, subjects will receive a 14-day course of rifaximin (550 mg PO TID). During these 14 days, subjects will record their symptoms and bowel habits. Subjects will return to the clinic after completion of the medication and will undergo repeat evaluation via rectal sensitivity testing to assess for change in rectal sensitivity.

Based on this trial design, predict the completion outcome and termination type (if applicable).
