 | Hazard Information | Back Directory |  | [Description] 
 Histrelin is a synthetic gonadotropin-releasing hormone (GNRH) agonist that binds to the GNRH receptor (GNRHR; Ki = 0.2 nM in CHO cells expressing the human receptor). It stimulates release of oxytocin and vasopressin ex vivo from the isolated rat hypothalamo-neurohypophysial system at a concentration of 100 nM. In vivo, the initial dose of histrelin (100 μg) stimulates acute increases in luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone serum levels (50-, 2.5-, and 15-fold, respectively), while chronic treatment leads to 95% decreases in LH and FSH responses in rhesus monkeys. Formulations containing histrelin have been used in the treatment of advanced prostate cancer and central precocious puberty.
 |  | [Uses] 
 Histrelin acetate, a GnRH analogue, is a GnRH Receptor agonist. Histrelin acetate increases serum luteinising hormone (LH), follicle stimulating hormone (FSH) and testosterone levels. Histrelin acetate can be used in the research of prostate cancer, endometriosis[1][2][5].
 |  | [Definition] 
 ChEBI: An acetate salt obtained by combining histrelin with acetic acid. The amount of acetic acid present can vary and a variable amount of water may be present. Histrelin acetate is used as a subcutaneous hydrogel implant for the treatment of prostate cancer an
 for the suppression of gonadal sex hormone production in children with central precocious puberty.
 |  | [in vivo] 
 
 Histrelin (0.1 mg/kg, subcutaneous injection) acetate rescues the circulating LH concentrations in Csfmop/Csfmop mice[2].Histrelin (10,30, or 100 μg /day, subcutaneous injection) acetate reduces the number of endometrial glands and atrophied the stroma in rabbits[3].
