Trelstar is a brand name for the medication triptorelin. It belongs to a class of drugs called gonadotropin-releasing hormone (GnRH) agonists. It is primarily prescribed for the treatment of advanced prostate cancer. In prostate cancer, Trelstar works by reducing the production of testosterone, which can slow down the growth and spread of cancer cells.
