简要总结
This study is to compare the efficacy and safety of polyethylene glycol (PEG) 3350 with that of prucalopride in the treatment of chronic constipation in females. A total of 240 patients will be randomly allocated to treatment with one or the other agent. The study consists of a 14-day run-in period, with treatment subsequently administered for 28 days on a daily basis. During the study, patients will fill in a stool diary, samples of faeces will be collected, and colonic transit time will be measured prior to therapy, and from days 22 to 28 of treatment. The proportion of patients with normalised bowel movements (three or more spontaneous movements) during the last week of the study (days 22 to 28 of treatment) will be compared between treatments.

- •Sensation of anorectal blockage in at least 25% of defecations.
- •Manual manoeuvres to facilitate at least 25% of defecations.
- •Less than 3 SCBMs during the last week of the run-in period.
- •Willing and able to follow the entire procedure and to comply with study instructions.
排除标准

- •Any oral purgatives/laxatives and prokinetics within the last 14 days prior to dosing and during the study.
- •Any opioids, anticholinergics, tricyclic anti-depressants, monoamine-oxidase inhibitors or iron preparations within the last 4 weeks prior to dosing.
- •Any calcium-antagonists, beta-blockers or diuretics within the last 4 weeks prior to dosing.
- •Other investigational drugs or prescribed medications affecting gastrointestinal function such as antispasmodics, drugs affecting motility (e.g. erythromycin), anthraquinones, ondansetron or other 5-hydroxytryptamine-3 (5-HT3) antagonists.
- •Any other medication which in the opinion of the investigator could interfere with the principal function of the gastrointestinal tract.
- •Insufficient documentation of chronic constipation during the run-in period.
- •Diarrhoea during the run-in period.
- •Anamnesis/medical history with clinically relevant findings in the gastrointestinal tract during proctoscopy, colonoscopy, sigmoidoscopy or computer tomography, or any other condition which in the Investigator's opinion, may put the patient at significant risk, may confound the study results or may interfere significantly with the results of the study.
- •Participation in another clinical study of drugs or devices parallel to or less than 90 days before study entry or previous participation in this study.
- •Gastrointestinal surgery within the last 6 months prior to the start of the study.
