초록

Based on published guidelines on the management of chronic constipation, secondary causes should be excluded and then patients should be told to increase their dietary fiber intake to 20-25 g per day. If these measures do not improve the symptoms, conventional laxatives are generally the next choice. Although there is limited evidence for the efficacy of these older laxatives due to a lack of well-designed clinical trials, most clinicians agree that they are effective at relieving the symptoms of constipation. Conventional laxatives include bulk-forming, osmotic, and stimulant laxatives. Bulking laxatives consist of fiber such as psyllium, cellulose, and bran. Osmotic laxatives are classified into sugar-based laxatives and polyethylene glycol. Bisacodyl and sodium picosulfate are stimulant laxatives. Understanding their mechanisms of action, efficacy, and side effects might improve the quality of life of patients suffering from chronic constipation.
