Trelstar (Triptorelin Pamoate Vial) is a prescription medication used in men to treat the symptoms of prostate cancer. Trelstar is a man-made form of a hormone that regulates many processes in the body. It has been designed to mimic the actions of gonadotropin releasing hormone (GnRH or luteinizing hormone releasing hormone, LHRH). Trelstar works by reducing the amount of testosterone in the blood, which can cause the prostate cancer to grow. This medication will only treat the symptoms of prostate cancer and it does not treat the cancer itself.
We currently offer the brand Trelstar from Canada manufactured by Knight Therapeutics Inc. It is available in the strength of 3.75 mg slow release 28 day vial and 11.25 mg slow release three month vial. The generic version is not available.
