Triptorelin, sold under the brand names Decapeptyl and Gonapeptyl among others, is a medication that acts as an agonist analog of Gonadotropin-releasing hormone, thus reversibly repressing expression of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
It is a decapeptide (pGlu-His-Trp-Ser-Tyr-D-Trp-Leu-Arg-Pro-Gly-NH2) and a gonadotropin-releasing hormone agonist (GnRH agonist) used as the acetate or pamoate salts.
Triptorelin is a synthetic decapeptide agonist analog of luteinizing hormone releasing hormone (LHRH). Possessing greater potency than endogenous LHRH, triptorelin reversibly represses gonadotropin secretion. After chronic, continuous administration, this agent effects sustained decreases in LH and FSH production and testicular and ovarian steroidogenesis. Serum testosterone concentrations may fall to levels typically observed in surgically castrated men.
Primary indications include endometriosis, for the reduction of fibroids, for prostatic cancer, and to treat male hypersexuality with severe sexual deviation.The drug has also been used off label to delay puberty in patients with gender dysphoria.
