Patients must report ≥ 3 days with IBS-related abdominal pain/discomfort plus at least 3 days of 2 or more of the following events during the baseline period:

  1. ≥ 3 bowel movements/day
  2. Bowel urgency
  3. Loose or watery stool

(2) Over the last week did you have satisfactory relief of your overall IBS-D symptoms?
    • Patients with hard or lumpy stools for more than one day during the baseline period
