Research warning. Sincalide contains sodium metabisulfite, which may cause allergic-type reactions, including anaphylaxis and life-threatening asthmatic episodes, in susceptible individuals. Serious reactions may occur during or soon after administration, and appropriate medical support should be readily available.

Sincalide (also known as Kinevac, Sincalida, Sincalidum, Syncalide) is a metabolic research peptide. Sincalide, also known as Kinevac, is an FDA-approved cholecystokinin A receptor agonist used in diagnostic imaging and to stimulate pancreatic secretion.

Sincalide is a cholecystokinin (CCK) analog and a cholecystokinin A receptor agonist. It is FDA-approved for use in adults to stimulate gallbladder contraction for diagnostic imaging or bile sample collection, to stimulate pancreatic secretion in combination with secretin, and to accelerate barium meal transit through the small bowel during X-ray examinations. Approved in 1976, sincalide is marketed as Kinevac and is administered intravenously. Research on sincalide often focuses on its clinical utility, proper infusion methodology, and its role in cholescintigraphy.

7 Frequently asked questions

What is sincalide used for?
Sincalide is used in adults for diagnostic purposes. It helps stimulate gallbladder contraction for imaging or bile collection, stimulates pancreatic secretion when combined with secretin, and speeds up the movement of a barium meal through the small intestine during X-ray examinations.
How does sincalide work?
Sincalide functions as a cholecystokinin A receptor agonist. This means it mimics the natural hormone cholecystokinin, binding to and activating its receptors to stimulate processes like gallbladder contraction and pancreatic secretion.
Is sincalide FDA approved?
Yes, sincalide, marketed as Kinevac, is FDA approved. It received its initial approval in 1976 and is used for various diagnostic applications related to the gallbladder and pancreas.
What are the side effects of sincalide?
Common side effects of sincalide include abdominal discomfort or pain and nausea. More serious adverse reactions can include anaphylaxis, anaphylactic shock, evacuation of gallstones, and, in pregnant women, preterm labor or spontaneous abortion.
What are the contraindications for sincalide?
Sincalide is contraindicated in patients with a history of hypersensitivity to sulfites or sincalide itself. It is also contraindicated in individuals who have an intestinal obstruction.
