Plain English Summary
Background and study aims.
Diarrhoea-predominant irritable bowel syndrome (IBS-D) affects around 3% of the population and is characterised by abdominal pain and frequent loose bowel movements. There are few treatments for these symptoms that work and this study aims to see whether Jianpi Shugan recipe might help those with IBS-D. Previous studies have suggested a benefit but this needs to be confirmed.
Who can participate?
Patients diagnosed by their doctors as having diarrhoea-predominant irritable bowel syndrome .
What does the study involve?
Patients will be randomly allocated either to take Jianpi Shugan recipe herbal granules with a placebo (dummy) tablet, or to take Pinaverium with placebo granules for 4 weeks. At the beginning of the study, an examination of the lower bowel will be made and a small specimen taken from the lining (biopsy). This procedure is routinely performed to identify the different causes of diarrhoea.
What are the possible benefits and risks of participating?
We are hoping that towards the end of the 4-week period diarrhoea and abdominal pain will improve. The drugs has been used for many years and the side effects are well recognised. Only a very few will not tolerate the drug because of abdominal discomfort, constipation, diarrhoea, nausea, rash etc.
