A Phase IIIb/IV, Multi-centre, Double-blind, Randomised, Placebo-controlled Parallel Group Study to Compare the Efficacy and Safety of Movicol® With Placebo in Patients With Constipation Associated With Irritable Bowel Syndrome (IBS)
Multi-centre, double-blind, randomised, placebo-controlled, parallel group study.
Patients will be treated for 28 days, with clinical assessments carried out over 2 visits. Follow-up will be performed via telephone at a specific interval during the study to determine the outcome of unresolved AEs, any new drug-related AEs or any pregnancies.

Prescription and OTC medications not related to constipation are permitted and must be fully documented, but any changes (e.g., dosage, regimen) are to be limited as much as possible.
