Objective To evaluate the potential role of tegaserod in the management of functional dyspepsia (FD) and gastroesophageal reflux disease
(GERD) in patients with chronic constipation and to determine the possible efficacy of tegaserod on solid-phase gastric emptying
and gastric hypersensitivity.
Method This was an exploratory open-label trial of tegaserod therapy for dyspepsia and reflux symptoms in patients with chronic constipation.
The study cohort consisted of 90 patients randomized to three treatment groups for a study period of 4 weeks (tegaserod 6 mg,
twice daily; esomeprazole 40 mg, once daily; tegaserod 6 mg, twice daily plus esomeprazole 40 mg, once daily). Twenty healthy
volunteers provided control values. Clinical symptoms were evaluated by one of the investigators using a Gastrointestinal
Symptom Rating Scale (GSRS). Solid-phase gastric emptying and colonic transit were measured by the radiopaque barium marker
method, and the water load test (WLT) was used to evaluate gastric sensation and the function of proximal stomach. The proportions
of patients with complete relief of epigastric pain /discomfort, epigastric fullness, early satiety and heartburn in the tegaserod
group and the tegaserod plus esomeprazole group were compared with the esomeprazole group, respectively.
Results The mean global gastrointestinal (GI) scores of all three treatment groups reported using the GSRS showed the same trend,
with decreasing scores over the 4-week study period indicating a reported decreasing severity of symptoms that was significantly
different from baseline values. Patients in the tegaserod plus esomeprazole group reported the lowest global GI scores after
4 weeks, as expected. Solid-phase gastric emptying (GER) and colonic transit (CTT) increased significantly in the tegaserod
6 mg twice daily group compared with baseline. These parameters did not change in the esomeprazole group at week 4 compared
with baseline. In terms of gastric sensation, in the tegaserod group, the proportions of patients with hypersensitivity of
the first perception threshold did not change at week 2 or week 4 compared with baseline; however, in this group and in the
tegaserod plus esomeprazole group, the proportions of patients with hypersensitivity of discomfort threshold decreased significantly
at week 4 compared with baseline. In the esomeprazole group, there were no changes in the proportions of patients with hypersensitivity
of the first perception threshold and discomfort threshold at week 2 or 4 compared with baseline. No severe adverse events
were recorded, and the medications were in general well-tolerated.
Conclusion Tegaserod is effective and safe at improving dyspepsia and reflux symptoms in patients with chronic constipation, and tegaserod
plus esomeprazole is superior to esomeprazole alone in the resolution of epigastric pain/discomfort and heartburn. 相似文献

Effects of prucalopride on colonic transit, anorectal function and bowel habits in patients with chronic constipation 总被引:5,自引:0,他引:5
Sloots CE Poen AC Kerstens R Stevens M De Pauw M Van Oene JC Meuwissen SG Felt-Bersma RJ 《Alimentary pharmacology & therapeutics》2002,16(4):759-767
BACKGROUND: There is a need for better tolerated drugs to normalize bowel function in chronic constipation. Prucalopride is a highly selective, specific, serotonin4 receptor agonist with enterokinetic properties. AIM: To evaluate the effects of prucalopride on bowel function, colonic transit and anorectal function in patients with chronic constipation. METHODS: Twenty-eight patients were enrolled in this double-blind, placebo-controlled, crossover study (prucalopride: 1 mg, n=12; 2 mg, n=16). Patients kept a bowel function diary. Colonic transit times and anorectal function (anal manometry, rectal sensitivity and rectal compliance) were assessed. RESULTS: Prucalopride (1 mg) compared to placebo significantly increased the mean number of spontaneous complete, spontaneous and all bowel movements per week. Prucalopride (1 mg) significantly decreased the percentage of bowel movements with hard/lumpy stools and straining and increased the urge to defecate. Prucalopride (1 and 2 mg) decreased the mean total colonic transit time by 12.0 h (prucalopride 42.8 h vs. placebo 54.8 h; P=0.074). No statistically significant effects were found in any of the anorectal function parameters. Prucalopride was well tolerated. There were no clinically relevant changes in standard safety parameters. CONCLUSIONS: Prucalopride significantly improves stool frequency and consistency, and the urge to defecate, and may decrease colonic transit times in patients with chronic constipation. 相似文献

Effects of psyllium therapy on stool characteristics, colon transit and anorectal function in chronic idiopathic constipation 总被引:3,自引:2,他引:3
Background: Psyllium is widely used in the symptomatic therapy of constipation. Its effects on colonic function and their correlation with symptomatic response have not been defined. Methods: After a 4-week baseline, placebo, run-in phase, 22 subjects with idiopathic constipation confirmed by prospectively administered stool diaries were randomly assigned to receive either psyllium (5 g b.d., 11 patients) or placebo (11 patients) for 8 weeks, followed by another 4-week wash-out, placebo phase. A colon transit study and anorectal manometry were performed at the beginning and at the end of each study phase. Subjects recorded, in diaries, their daily stool frequency, difficulty with defecation and weekly stool weight. Results: Stool frequency increased significantly after 8 weeks of psyllium treatment (3.8 ± 0.4 vs. 2.9 ± 0.1 stools/week, P < 0.05) as did stool weight (665.3 ± 95.8 g vs. 405.2 ± 75.9 g, P < 0.05). Subjects also reported an improvement in stool consistency (stool consistency score: 3.2 ± 0.2 vs. 3.8 ± 0.2, P < 0.05) and pain on defecation (pain score: 2.0 ± 0.4 vs. 2.6. ± 0.5, P < 0.05) on psyllium. Colon transit and anorectal manometry parameters were unchanged on psyllium. Subjects treated with placebo did not show any change in either subjective or objective measures of constipation. Conclusions: Psyllium increases stool frequency and weight and improves stool consistency in idiopathic constipation. These effects are not associated with significant changes in either colonic or rectal motor function. We suggest that the beneficial effects of psyllium in constipation are primarily related to a facilitation of the defecatory process. 相似文献

《Expert opinion on drug safety》2013,12(2):313-327
A growing body of evidence implicates abnormal serotonergic regulation of gastrointestinal function in the pathogenesis of the irritable bowel syndrome (IBS). Drugs targeting this system are therefore attractive concepts. The partial 5-HT4 receptor agonist tegaserod might be predicted to have positive therapeutic effects on a constipated and uncomfortable gut. However, IBS runs a chronic, benign course and carries no associated mortality, so it is imperative that the safety profile of new pharmacological agents made available to physicians is exemplary. The authors review the evidence for 5-HT in the aetiology of IBS and its symptoms, and the data available concerning the partial 5-HT4 receptor agonist tegaserod, in terms of rationale, efficacy and safety. 相似文献
