Sincalide is a diagnostic agent that works by stimulating processes in specific organs of the body. Sincalide is injected in preparation for certain medical tests.

Sincalide is used to help diagnose disorders of the gallbladder or pancreas. It is also used to speed up digestion of barium, a contrast agent, given in preparation for x-ray examination of the intestines.

Sincalide may also be used for purposes not listed in this medication guide.

Sincalide dosing information

Usual Adult Dose for Barium Meal Transit:

To accelerate the transit time of a barium meal through the small bowel, sincalide should be administered after the barium meal is beyond the proximal jejunum (sincalide, like cholecystokinin, may cause pyloric contraction). The recommended dose is 0.04 mcg per kg IV over a 30- to 60-second interval. If satisfactory transit of the barium meal has not occurred in 30 minutes, a second dose may be administered.

To reduce intestinal side effects, a 30-minute IV infusion 0.12 mcg per kg diluted to approximately 100 mL with sodium chloride may be administered.

Usual Adult Dose for Pancreatic Secretion:

To test pancreatic function: 0.25 units per kg IV over a 60-mlnute period.

Thirty minutes after the initiation of the infusion, a separate IV infusion at a total dose of 0.02 mcg per kg is administered over a 30-minute interval (for example, the total dose for a 70 kg patient is 1.4 mcg of sincalide; therefore, dilute 1.4 mL of reconstituted solution to 30 mL with sodium chloride Injection and administer at a rate of 1 mL per minute).

Usual Adult Dose for Gallbladder Contraction:

Initial dose: IV: 0.02 mcg/kg over 30 to 60 minutes

If satisfactory contraction of the gallbladder does not occur in 15 minutes, a second dose, 0.04 mcg/kg IV may be administered.

To reduce intestinal side effects, an intravenous infusion may be prepared at a dose of 0.12 mcg/kg in 100 mL of sodium chloride Injection and given at a rate of 2 mL per minute. Alternatively, an intramuscular dose of 0.1 mcg/kg may be given.

When sincalide is used in cholecystography, roentgenograms are usually taken at five-minute Intervals after the injection. For visualization of the cystic duct, it may be necessary to take roentgenograms at one-minute intervals during the first five minutes after the injection.

What other drugs will affect sincalide?

Other drugs may interact with sincalide, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using.
