Lupron (leuprolide; Takeda/AbbVie) is a gonadotropin-releasing hormone (GnRH) agonist which acts on the pituitary gland in the brain to stimulate luteinizing hormone (LH) release, resulting in a temporary surge in serum testosterone levels known as "flare".
With continued use, GnRH agonists such as Lupron cause downregulation of GnRH receptors in the pituitary gland, generating a significant reduction in LH and follicle-stimulating hormone secretion. This has the effect of complete shutdown of testosterone production in the testes, resulting in chemical castration where levels of the hormone drop by up to 95% and tumor growth is significantly reduced.
