Prostate cancer hormone therapy treatment may use LHRH agonists, also known as Luteinizing hormone-releasing hormone (LHRH) agonists or Gonadotropin releasing hormone (GnRH) agonists. Luteinizing hormone-releasing hormone and Gonadotropin-releasing hormone are essentially the same chemicals which are released by the hypothalamus when it detects lowering levels of testosterone. An agonist is a chemical that mimics a naturally-occurring substance in the body and produces the same physiological effect. The agonist will occupy the cell receptors of the chemical it is mimicking. An agonist has a longer biological half-life, meaning the body takes longer to metabolize and eliminate the agonist. The agonist therefore will occupy a receptor for a longer period of time. Agonists are sometimes referred to as analogues because they are inserted beneath the skin where they continuously emit LHRH agonist of GnRH agonist for a prostate cancer treatment. LHRH and GnRH agonists are also administered as an injection that can be performed in a doctor’s office or at home.(http://www.prostate-cancer.com/)

Triptorelin is a synthetic analogue of gonadorelin (natural GnRH decapeptide) with amino acid (D-tryptophan) substitution in position 6 to inhibit rapid degradation for long activity. Used as triptorelin pamoate or acetate form, triptorelin is used as an antineoplastic in the palliative treatment of prostatic carcinoma, administered intramuscularly. Other analogues with two substituents in position 6 and 10 include Buserelin, Deslorelin. Goserelin, Histrelin, Leuprolide, Nafarelin,
