Histrelin acetate is a synthetic nonapeptide analog of the naturally occurring gonadotropin releasing hormone (GnRH) or luteinizing hormone (LH). It has greater potency than the naturally occurring hormone and is a GnRH agonist. It inhibits the secretion of gonadotropin in continuous dosage. Histrelin acetate is imbedded in a hydrophilic polymer surgically implanted in the subcutaneous tissue of the upper arm as the delivery system.
After subcutaneous implantation of histrelin acetate, there is an initial stimulatory phase of increased circulating levels of LH and FSH (follicle stimulating hormone) resulting in a transient increase in the concentration of gonadal steroids. Long-term treatment with histrelin acetate leads to a reversible down-regulation of GnRH receptors in the pituitary gland and desensitization of the pituitary gonadotropes. As a result, FSH and LH levels decrease to castrate or prepubertal levels within a month. Serum concentrations of estrogen and testosterone also decrease, generally leading to the cessation of secondary sexual development and slowing of linear growth velocity in children. It is used in the treatment of central precocious puberty and prostate cancer.
This policy addresses only the use of histrelin acetate for the treatment of prostate cancer.
