Definition

A drug used to treat adults with advanced prostate cancer. Relugolix binds to gonadotropin-releasing hormone (GnRH) receptors in the pituitary gland, which blocks the pituitary gland from making the hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH). This causes the testicles to stop making testosterone. Relugolix may stop the growth of cancer cells that need testosterone to grow. It is a type of GnRH antagonist. Also called Orgovyx.
