Summary
Macimorelin is a diagnostic agent for adult growth hormone deficiency, and the test depends on a normal pituitary growth hormone response. Glucocorticoids can alter growth hormone secretion and may make the result unreliable. A false result could lead to misdiagnosis or unnecessary treatment.
What this interaction means in plain words
Macimorelin and Prednisolone 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.
Macimorelin belongs to Endocrine; Prednisolone belongs to Endocrine.
Why it happens
Glucocorticoids suppress pituitary growth hormone release, which can confound the macimorelin stimulation test; the exact mechanism is not fully characterised.
What to do
Where clinically possible, delay macimorelin testing until prednisolone has been stopped and sufficiently washed out. If steroids cannot be stopped, interpret the result with caution and document the steroid exposure.
