The corticorelin stimulation test helps to differentiate between the causes for adrenocorticotropic hormone (ACTH)-dependent hypercortisolism. It is used to distinguish a pituitary source of excessive ACTH secretion from a different source.
- If corticorelin injection increases plasma levels of ACTH and cortisol, a diagnosis of Cushing's disease is achieved (ACTH of pituitary origin).
- If corticorelin injection leads to little or no response in plasma levels of ACTH or cortisol, a diagnosis of ectopic ACTH syndrome is confirmed.
The most common side effects (in 1% to 10% of patients) are transient dysosmia and dysgeusia (distortion of the sense of smell and taste), as well as a sensation of warmth. About 0.1 to 1% of patients experience hypersensitivity, hypotension (lowering of blood pressure), tachycardia (increased heart rate), flush, dyspnoea (breathing difficulties), a cold sensation in the throat, the urge to urinate, and dizziness. Pituitary apoplexy has been reported in patients with pituitary tumours.
