Corticorelin

Corticorelin (INN) is a diagnostic agent. It is a synthetic form of human corticotropin-releasing hormone (hCRH).

The corticorelin stimulation test helps to differentiate between the etiologies of adrenocorticotropic hormone (ACTH)-dependent hypercortisolism. It is used to evaluate the status of the pituitary-adrenal axis in the differentiation of a pituitary source from an ectopic source of excessive ACTH secretion.
