Sincalide

Sincalide is a synthetic octapeptide corresponding to the C-terminal active fragment of cholecystokinin (CCK-8). It is a potent stimulant of gallbladder contraction and pancreatic enzyme secretion, widely used as a diagnostic agent in gastrointestinal function testing. Sincalide injection is the standard provocative agent for cholecystography, pancreatic function assessment, and gastric emptying studies, offering a safer alternative to the traditional fatty meal test.
