Teduglutide is primarily used in the treatment of Short Bowel Syndrome (SBS) in patients who are dependent on parenteral support. It works by promoting the growth and repair of the intestinal lining, which enhances the absorption of nutrients and fluids. This can significantly reduce the need for intravenous feeding, improving the quality of life for patients. Additionally, it is being investigated for potential use in other gastrointestinal disorders where enhanced intestinal absorption is beneficial.
