NCIt definition : A long-acting, synthetic nonapeptide analog of gonadotropin-releasing hormone (GnRH)
with potential anti-tumor activity. Upon administration, histrelin binds to and activates
GnRH receptors; prolonged administration results in pituitary GnRH receptor desensitization
and inhibition of follicle stimulating hormone (FSH) and luteinizing hormone (LH)
secretion, leading to a significant decline in testosterone production in males and
may inhibit androgen receptor-positive tumor progression; in females, prolonged administration
results in decreased estradiol production.;
