Triptorelin, a decapeptide, is a gonadotropin-releasing hormone agonist (GnRH agonist). By causing constant stimulation of the pituitary, it decreases pituitary secretion of gonadotropins luteinizing hormone (LH) and follicle stimulating hormone (FSH). Like other GnRH agonists, triptorelin may be used in the treatment of hormone-responsive cancers such as prostate cancer or breast cancer, precocious puberty, estrogen-dependent conditions (such as endometriosis or uterine fibroids), and in assisted reproduction. Triptorelin is marketed under the brand names Decapeptyl (Ipsen) and Diphereline and Gonapeptyl (Ferring Pharmaceuticals).



Triptorelin is a synthetic analogue of natural gonadotropin-releasing hormone. Initial admin stimulates the release of pituitary gonadotrophins with a transient increase in testosterone levels in men and in oestradiol levels in women, leading to an initial worsening of symptoms during the first wk. Prolonged admin leads to a suppression of gonadotrophins and a decrease in plasma testosterone or oestradiol after approximately 20 days, which is maintained for as long as triptorelin is admin.

Rapidly absorbed with peak plasma concentrations after 40 minutes (subcutaneous injection).

Half life: 7.5 hours.
