- Primary Outcome Measures
Name Time Method Comparison of the responders during Period 2 of the study (weeks 3 - 6) in the treatment group and those in the placebo group. Response is defined as those participants who give an assessment of 'satisfactory improvement' on at least 50% of occasions over the 4-week trial period (Period 2) to the global question on the diary card.
- Secondary Outcome Measures
Name Time Method 1. Comparison of stool frequency and type, laxative use, Patient Assessment of Constipation Symptoms (PAC-SYM), and Patient Assessment of Constipation Quality of Life Questionnaire (PAC-QOL) 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. Comparison will be made between the pre- and post-trial transit study as an objective marker of a reduction in transit time.<br>2. Graphical representation of the temporal changes in stool frequency and type and analysis to assess any drop-off of effect after 8 weeks of use in those receiving Nalcol™ for 8 weeks or in the whole group<br>3. A comparison of pre-treatment versus treatment symptom levels in the whole (n = 120), i.e., Period 1 versus Period 3<br>4. Comparison of stool bacterial counts between the treatment and placebo groups in the selected subset after each Period
