Sincalide is widely used in medical diagnostics, particularly for imaging and functional testing of the gallbladder and pancreas. It stimulates gallbladder contraction and promotes the secretion of digestive enzymes from the pancreas, making it valuable in cholescintigraphy to assess gallbladder ejection fraction and detect biliary dyskinesia. Additionally, it aids in evaluating pancreatic function and identifying obstructions in the biliary tract. In research, sincalide is utilized to study the role of cholecystokinin in gastrointestinal physiology, appetite regulation, and pain modulation. Its ability to mimic natural cholecystokinin effects makes it a crucial tool in both clinical and experimental settings.
