Protirelin is the pharmaceutically available synthetic analogue of the endogenous peptide thyrotropin-releasing hormone (TRH). It is a tri-peptide tropic hormone, released by the hypothalamus, that stimulates the release of Thyroid Stimulating Hormone (TSH) and prolactin from the anterior pituitary.
Although not currently available in any FDA-approved product, protirelin is a component of the TRH Test where it is used to test the response of the anterior pituitary gland in conditions such as secondary hypothyroidism and acromegaly.
