Primary	Proportion of patients who have a response in pain	Patients who record on = 50% of the days a reduction of = 30% from their average baseline score for their worst abdominal pain.The standard 11-point numeric rating scale (from 0=none to 10=worst possible pain) will be used to measure abdominal pain.	12 weeks
Primary	Proportion of patients who have a response in stool consistencies	Patients who record a stool-consistency score < 5 in the same days in which they record a reduction of = 30% from their average baseline score for their worst abdominal pain .For abnormal defecation, stool frequency and form will be measured using the Bristol Stool Form Scale (BSFS).	12 weeks
Secondary	Evaluation of Pain relief	reduction of = 30% from baseline in the score for the worst abdominal pain on = 50% of days	16 weeks
