Effect of Ranolazine on Gastrointestinal Motor Function and Pain in Patients With IBS-D (Ranolazine)
February 16, 2016 updated by: Yuri A. Saito Loftus, Mayo Clinic
Effect of Ranolazine on Gastrointestinal Motor Function and Pain in Patients With Diarrhea-predominant Irritable Bowel Syndrome (IBS-D)
Will Ranolazine improve bowel function and abdominal pain in human subjects with IBS-D?
Study Overview
Status
Terminated
Intervention / Treatment
Detailed Description
This is a randomized double-blind placebo-controlled pilot study that will use validated bowel questionnaires to evaluate the effects of ranolazine administered orally twice daily in patients with diarrhea predominant IBS (IBS-D).
The study will consist of a 2 week run in period, followed by 4 weeks of treatment period with oral ranolazine 1000 mg twice daily.
Primary endpoint of the study will be the average Bowel Symptom Scale (BSS) scores for diarrhea and adequate relief of IBS pain and discomfort are secondary end points.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Diarrhea Using the Bowel Symptom Score (BSS).
Time Frame: baseline to 4 weeks
|
BSS is a 100-mm visual analog scale for each symptom of Irritable Bowel Syndrome (IBS) (pain or discomfort, bloating, and diarrhea) with an overall severity score.
Lower scores indicate symptoms are not present and higher scores indicate severe symptoms.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mean Abdominal Pain
Time Frame: baseline to 4 weeks
|
Daily abdominal pain intensity was rated using an 11-point (0-10) numeric rating scale, with 0 being no pain, and 10 being the worst pain imaginable.
Participants were asked to rate their worst abdominal pain over the past 24 hours.
