Triptorelin is a man-made form of a hormone that regulates many processes in the body. Triptorelin overstimulates the body's own production of certain hormones, which causes that production to shut down temporarily.

Triptorelin is used to treat the symptoms of prostate cancer. Triptorelin treats only the symptoms of prostate cancer and does not treat the cancer itself. Use any other medications your doctor has prescribed to best treat your condition.


Triptorelin is a synthetic decapeptide (D-Trp6 GnRH) analogue of natural GnRH. Studies in animals and man have shown that continued administration of triptorelin exerts, after a short initial stimulation, an inhibitory effect on the gonadotropin secretion with consequent suppression of testicular and ovarian function.‚Äč

The first administration of Decapeptyl 3-month stimulates the release of pituitary gonadotropins with a transient increase in testosterone levels ('flare-up'). Prolonged administration leads to a suppression of gonadotropins and a fall in plasma testosterone to castrate levels after approximately 20 days and which continues for as long as the product is administered.
