Histrelin Acetate (CAS: 76712-82-8), a synthetic gonadotrophin-releasing hormone (GnRH) agonist, was introduced as a first-line therapy for the treatment of central precocious puberty. When administered over a prolonged period, it suppresses the release of gonadotrophin, inhibits ovarian and testicular steroidogenesis, and prevents sexual maturation. Superior to the traditional therapy with progestational agents, histrelin appears to have decelerating effects on skeletal maturation allowing more statural growth and significantly increased final adult height. Histrelin has also been used to treat other disorders including endometriosis, polycystic ovarian disease, uterine leiomyomas, severe premenstrual syndrome and to prevent acute intermittent porphyria.
Definition: An oligopeptide comprising pyroglutamyl, histidyl, tryptophyl, seryl, tyrosyl, 1-benzyl-D-histidyl, leucyl, arginyl, and N-ethylprolinamide residues joined in sequence. It is a synthetic nonapeptide analogue of gonadotro in-releasing hormone, and is used as a subcutaneous hydrogel implant (particularly as the diacetate salt) for the treatment of prostate cancer and for the suppression of gonadal sex hormone production in children with central precocious puberty. Used for precocious puberty.
Biochem/Physiol Actions: Histrelin Acetate is a GnRH (gonadotropin-releasing hormone) agonist, histerelin. GnRH (Glp-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2), which is also referred as LHRH (luteinizing hormone-releasing hormone) or gonadorelin, is crucial for mammalian reproduction and is released from hypothalamic neurons. It is responsible for the secretion of gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), from the pituitary glands. Mutations in GnRH are associated with normosmic congenital hypogonadotropic hypogonadism. Histerelin is used for the treatment of central precocious puberty in children. It inhibits actions of sex steroids on the male and female reproductive organs.
It is available as a daily intramuscular injection. Histrelin is also available in a 12-month subcutaneous implant (Vantas) for the palliative treatment of advanced prostate cancer (since 2005 in the US, and since Jan 2010 in the UK. A 12-month subcutaneous implant (Supprelin LA) for central precocious puberty (CPP) was approved on May 3, 2007 by the U.S. Food and Drug Administration.
