Used primarily as a stimulant laxative for the treatment of constipation. It works by increasing intestinal motility and promoting water secretion into the colon, helping to soften stool and facilitate bowel movement. Commonly found in over-the-counter medications for short-term relief of constipation. Also used as a bowel preparation agent before medical procedures such as colonoscopy, often in combination with other laxatives to ensure complete bowel cleansing. Its delayed action makes it suitable for overnight effect, typically producing results within 6–12 hours after ingestion.
