The objective of this randomized clinical trial is to compare prucalopride versus bisacodyl as a stimulant agent for bowel cleansing preparation prior to colonoscopy in patients undergoing the procedure at the Endoscopy Unit of the Hospital de Clínicas. The main research questions this study aims to answer are:
Is prucalopride superior or equivalent to bisacodyl as a stimulant agent for bowel cleansing preparation before colonoscopy? Is the tolerability of prucalopride better, equivalent, or worse compared to bisacodyl? The investigators will compare the standard bowel cleansing preparation using polyethylene glycol (PEG) in combination with either bisacodyl or prucalopride as the stimulant agent.
Participants will be randomized into two groups, both receiving the same base preparation with different stimulant agents.
All patients over 18 years of age.
Without prior colonic surgical interventions.
Who attend the Digestive Endoscopy service to undergo a colonoscopy.
Patients who voluntarily choose not to participate in the study.
Pregnant women.
Patients with rectocolonic resections and/or ileostomies.
Inflammatory bowel disease.
