Triptorelin

Triptorelin is a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH) with a D-Trp substitution at position 6, making it approximately 100 times more potent than native GnRH. Like other GnRH agonists, Triptorelin initially stimulates pituitary gonadotropin release before inducing receptor downregulation and profound suppression of LH, FSH, and gonadal steroids. It is widely prescribed as a depot formulation for treatment of advanced prostate cancer, endometriosis, uterine fibroids, precocious puberty, and in assisted reproduction protocols. Its high potency and availability in sustained-release formulations make it one of the most commonly used GnRH agonists worldwide.
