Sincalide（Cat No.:I002853）is a synthetic peptide that mimics cholecystokinin (CCK), a hormone involved in digestive processes. It stimulates the gallbladder to contract and release bile, and prompts the pancreas to secrete digestive enzymes. Sincalide is primarily used in diagnostic imaging to evaluate gallbladder function and bile ducts during hepatobiliary scintigraphy. It also aids in assessing pancreatic disorders. By enhancing the visibility of these organs, Sincalide facilitates accurate diagnosis of conditions like gallbladder dysfunction and chronic pancreatitis, playing a crucial role in gastrointestinal diagnostics and patient care.
