Summary
H2 blockers can exaggerate the gastrin response to secretin stimulation, producing a false-positive result that suggests gastrinoma. This can lead to misdiagnosis and unnecessary investigation.
What this interaction means in plain words
Nizatidine 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
Acid suppression with nizatidine raises basal gastrin and alters the gastrin response to secretin, confounding the test.
What to do
Stop nizatidine at least 2 days before secretin stimulation testing, with the diagnostic team supervising acid control.
What to ask your pharmacist
