Hydrophilic, bulk-producing laxative that restores normal moisture level and bulk content of intestinal tract. In constipation, retains free water in intestinal lumen, thereby indirectly opposing dehydrating forces of the bowel; in diarrhea, when intestinal mucosa is incapable of absorbing fluid, drug absorbs fecal fluid to form a gel. In both conditions, peristalsis is encouraged and a well-formed stool is produced.
