Triptorelin- Summary
- Cagrilintide is a long-acting amylin analog developed by Novo Nordisk. Amylin is a peptide hormone co-secreted with insulin from pancreatic beta cells. Cagrilintide slows gastric emptying, suppresses glucagon, and reduces appetite via central amylin receptors. In combination with semaglutide (CagriSema), Phase 2 trials achieved approximately 15% body weight reduction. Phase 3 trials (REDEFINE program) are ongoing.
- Triptorelin is a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH) with 100x the potency of native GnRH. An FDA-approved drug (Trelstar) for prostate cancer and precocious puberty, it is also used in post-cycle therapy (PCT) to rapidly restart the hypothalamic-pituitary-gonadal (HPG) axis after anabolic steroid suppression.
