Abstract

Background & aims Although stimulant laxatives have been used for many years to treat patients with constipation, their clinical value has been questioned, and there have been few high-quality trials to assess their efficacy. We tested the efficacy and safety of 4 weeks of treatment with oral bisacodyl tablets in patients with chronic constipation, defined by Rome III criteria.Methods This randomized, double-blind, placebo-controlled, parallel-group study was conducted in 27 centers in the United Kingdom. After a 2-week baseline period without study medication, patients were randomly assigned, in a 2:1 ratio, to groups that were given 10 mg bisacodyl (n = 247) or placebo (n = 121), once daily, for 4 weeks. Patients used an electronic diary each day to record information relating to their constipation.Results The mean (± standard error of the mean [SEM]) number of complete spontaneous bowel movements (CSBMs) per week during the treatment period increased from 1.1 ± 0.1 in both groups to 5.2 ± 0.3 in the bisacodyl group and 1.9 ± 0.3 in the placebo group (P < .0001). All secondary end points (number of complete spontaneous bowel movements for each single week, number of spontaneous bowel movement (SBMs), and constipation-associated symptoms) differed significantly between groups, demonstrating efficacy for bisacodyl (P < .0001). Compared with baseline, there was a statistically significant improvement in the overall Patient Assessment of Constipation quality of life (PAC-QOL) score and all subscales (satisfaction, physical discomfort, psychosocial discomfort, worries and concerns) in the bisacodyl-treated patients, compared with those that received placebo (P ≤ .0070). Treatment with bisacodyl was well-tolerated.Conclusions Oral bisacodyl is an effective and well-tolerated treatment for patients with chronic constipation. It improves bowel function, constipation-related symptoms, and disease-related QOL.

  • Based on meta-analyzed data from 2 studies, SPS likely leads to a large increase in CSBMs per week (MD 2.54, 95% CI 1.07-4.01) and SBMs per week (MD 4.04, 95% CI 2.37-5.71), and improved stool consistency on the Bristol Stool Form Scale (MD 2.4 points higher, 95% CI 2.07-2.73) and PAC-QOL scores (MD 0.65, 95% CI 0.50-0.80) compared with placebo.

  • For bisacodyl at the initial starting dose of 10 mg compared with placebo, diarrhea occurred in 53.4% vs 1.7%, and abdominal pain occurred in 24.7% vs 2.5%.

    Table 3 (page unavailable) reports exactly the stated diarrhea and abdominal-pain percentages for bisacodyl versus placebo. However, those figures cover adverse events during the four-week treatment period, not events specifically occurring at the initial 10 mg dose; the Dose reduction section reports that the mean bisacodyl dose fell after week one.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
