Pharmacology
Relugolix is a nonpeptide GnRH receptor antagonist that competitively binds to pituitary GnRH receptors, reducing the release of LH and FSH and consequently suppressing testosterone to castrate levels.
ZOLADEX is a synthetic decapeptide analogue of GnRH that inhibits pituitary gonadotropin secretion; chronic administration suppresses serum testosterone in males to castrate levels and reduces serum estradiol in females to postmenopausal levels, leading to regression of hormone-sensitive tumors and accessory sex organ regression.
