Triptorelin is used to treat advanced prostate cancer in men, and is similar to a hormone that is naturally produced in the hypothalamus gland of the brain. It is a gonadotropin releasing hormone (GnRH) agonist, which is a medication that decreases the amount of certain hormones in the body. When given regularly, triptorelin decreases testosterone levels.
Triptorelin injections are also administered as treatment for a condition called central precocious puberty (CPP), which can cause children to enter puberty much earlier than anticipated.
