Itopride as an Adjuvant for Bowel Preparation in Patients With Chronic Constipation is Effective

Constipation Clinical Trial

Official title:
High Dose of Itopride: a Valid Adjuvant for Bowel Preparation in Patients With Chronic Constipation

Clinical Trial Summary

Bowel preparation is a major determinant of colonoscopy and colorectal surgery. Polyethylene glycol electrolyte solutions (PEG-E) are the most commonly used laxatives in China. However, a significant number of patients, especially those constipated patients, failed colonoscopies due to poor bowel cleaning. Inadequate preparation may also lead to missed colonic lesions. The study is based on the hypothesis: itopride hydrochloride, a prokinetic agent, its dual role as dopamine D2 receptor antagonism and acetylcho-linesterase inhibition make it an appropriate adjuvant for bowel preparation. It was reported to promote colonic peristalsis, shorten colonic transit time and accelerate propulsion of colonic luminal contents through inhibition of M3 receptor and dopamine D2 receptors in vitro and in vivo. So this study is to determine the efficacy, tolerance and safety of high dose of itopride, when given in different times before administration of PEG-E, for colonic preparation in patients with chronic constipation.

Clinical Trial Description

Colonoscopy is a reliable procedure for the investigation of colonic and distal terminal ileum disease. The diagnostic accuracy of colonoscopy is dependent on visualization of the colonic mucosa; hence an appropriate bowel preparation is essential for the examination. Despite multiple lavage were used throughout the years, the suboptimal cleaning level have been reported vary from 10% to more than 20% and up to one-third of incomplete or failed colonoscopies can be ascribed to poor bowel preparation. So it is important for us to search a new regimen for bowel preparation. ;
