Primary

MeasureTime frame
Main Objective: The primary objective of this study is to assess the efficacy of nalcol (number of responders) when used as an adjunct to usual laxatives in the treatment of patients with refractory constipation as compared to a placebo group (i.e. Period 2). ;Secondary Objective: A number of secondary analyses will be perform to further assess the response to the Nalcol treatment: Comparison of stool frequency and type, laxative use, and questionnaire responses between treatment and placebo groups during Period 2 of the study. PAC-SYM will be used to provide an overall symptom score; but each component will also be analysed separately to identify changes to individual symptoms. Post trial transit studies will be undertaken in those patients who have previously undergone a transit study. These will be compared to determine an objective reduction in transit time.
