Core Tip

Core tip: Selecting optimal purgatives is essential for achieving effective bowel preparation. Although polyethylene glycol is the most widely used solution, there are several agents for bowel cleansing including osmotic and stimulant agents. Thus, combination methods of these agents could be an option to improve the cleansing quality and patients’ adherence. We reviewed comparison studies between combination and single agent preparations. The biggest benefit of combinations in most studies is to reduce the volume of cleansing solutions, which could improve patients’ compliance for bowel preparation. However, new effective and well-tolerated combination preparations are required for more effective bowel preparations.
