Pharmacokinetic data
Elimination half-life	The elimination half-life for patients with hepatic impairment was similar to that of patients with renal impairment (geometric mean t(1/2, z): 6.6 h, 7.7 h and 7.6 h for Groups II, III and IV, respectively), but significantly longer than in healthy volunteers (2.8 h for Group I) Triptorelin is a gonadotropin-releasing hormone (GnRH) analogue with enhanced affinity for GnRH receptors and a prolonged half-life due to its resistance to enzymatic degradation.

Triptorelin, sold under the brand name Decapeptyl among others, is a medication that acts as an agonist analog of gonadotropin-releasing hormone, repressing expression of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

It is a decapeptide (pGlu-His-Trp-Ser-Tyr-D-Trp-Leu-Arg-Pro-Gly-NH₂) and a gonadotropin-releasing hormone agonist (GnRH agonist) used as the acetate or pamoate salts.

Primary indications include endometriosis, for the reduction of uterine fibroids, to treat prostate cancer, and to treat male hypersexuality with severe sexual deviation. The drug has also been used off label to delay puberty in patients with gender dysphoria.

It was patented in 1975 and approved for medical use in 1986. It is on the World Health Organization's List of Essential Medicines.
