Prostate Cancer Home > Firmagon Uses
How Does This Medicine Work?Firmagon works by binding to and blocking GnRH receptors in the pituitary gland (a tiny gland located beneath the brain). Normally, GnRH controls the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which increases the production of testosterone in the testes. By blocking GnRH receptors, Firmagon reduces the production and secretion of LH and FSH, resulting in decreased testosterone levels.
Testosterone stimulates the growth of prostate cancer cells. By reducing testosterone levels, Firmagon slows down the growth of prostate cancer.
Firmagon is a depot injection. After being injected, the medication forms a small mass, or depot, under the skin. Firmagon is slowly released from this mass into the bloodstream over the course of a month.
