Used to treat irritable bowel syndrome (IBS) and other functional gastrointestinal disorders. It works by relaxing the smooth muscles in the gut, helping to relieve symptoms like abdominal pain, bloating, and discomfort. Particularly effective in managing spasms in the large intestine without affecting normal gut motility. Commonly prescribed for patients with constipation-predominant or diarrhea-predominant IBS when spasms are a key symptom.
