Summary
Secretin is used in pancreatic and gastrinoma stimulation testing. Anticholinergic drugs such as scopolamine can blunt the response and cause false results.
What this interaction means in plain words
Scopolamine and Secretin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Muscarinic antagonism opposes secretin-stimulated pancreatic and gastric responses, causing pharmacodynamic antagonism.
What to do
Stop scopolamine before the test, allowing at least five half-lives where feasible. Interpret results cautiously if it cannot be withdrawn.
