- DrugBank Accession Number
- DB09067
- Background
Corticorelin, available commercially as corticorelin ovine triflutate (tradename Acthrel), is a synthetic form of the peptide human corticotropin-releasing hormone (hCRH), a potent stimulator of adrenocorticotropic hormone (ACTH) release from the anterior pituitary. Endogenous forms hCRH are involved in the stress response and its main function is stimulation of the pituitary to release ACTH.
It is used as a diagnostic agent to evaluate the status of the pituitary-adrenal axis in the differentiation of a pituitary source from an ectopic source of excessive ACTH secretion. It provides a differential diagnosis for Cushing's disease (a pituitary source of ACTH excess) or of ectopic ACTH syndrome (an ectopic source of ACTH excess). If corticorelin injection results in an increase of plasma ACTH and cortisol, the patient is diagnosed with Cushing's disease. However, if corticorelin injection does not result in an increase of plasma ACTH and cortisol, the patient is diagnosed with ectopic ACTH syndrome.

- Pharmacodynamics
In normal subjects, intravenous administration of corticorelin results in a rapid and sustained increase of plasma ACTH levels and a near parallel increase of plasma cortisol. In addition, intravenous administration of corticorelin to normal subjects causes a concomitant and prolonged release of the related proopiomelanocortin peptides β- and γ-lipotropins (β -and γ-LPH) and β-endorphin (β -END).
- Mechanism of action
Corticorelin is a potent stimulator of adrenocorticotropic hormone (ACTH) release from the anterior pituitary. It is used as a diagnostic agent to evaluate the status of the pituitary-adrenal axis in the differentiation of a pituitary source from an ectopic source of excessive ACTH secretion.
Target Actions Organism ACorticotropin-releasing factor receptor 1 ligand- Absorption
Plasma ACTH levels in normal subjects increased 2 minutes after injection of corticorelin doses of ≥0.3 mcg/kg and reached peak levels after 10-15 minutes. Plasma cortisol levels increased within 10 minutes and reached peak levels at 30 to 60 minutes.
- Volume of distribution
The mean volume of distribution for IR-corticorelin is 6.2 ± 0.5 L

- Toxicity
The severity of adverse effects to a corticorelin injection appear to be dose-dependent. Dosages above 1 mcg/kg are not recommended. While few adverse effects have been observed at the 1 mcg/kg or 100 mcg dose, higher doses have been associated with transient tachycardia, decreased blood pressure, loss of consciousness, and asystole.

- General Function
- G-protein coupled receptor for CRH (corticotropin-releasing factor) and UCN (urocortin). Has high affinity for CRH and UCN. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and down-stream effectors, such as adenylate cyclase. Promotes the activation of adenylate cyclase, leading to increased intracellular cAMP levels. Inhibits the activity of the calcium channel CACNA1H. Required for normal embryonic development of the adrenal gland and for normal hormonal responses to stress. Plays a role in the response to anxiogenic stimuli.
