Pharmacology
Triptorelin is a synthetic decapeptide GnRH agonist; chronic continuous administration suppresses LH and FSH secretion and markedly reduces testicular steroidogenesis, achieving medical castration levels of testosterone in men with advanced prostate cancer.
Leuprolide acetate is a GnRH agonist that potently inhibits gonadotropin secretion with continuous dosing; chronic administration suppresses LH and FSH, reducing testosterone to below castrate threshold (<=50 ng/dL) in males within two to four weeks of treatment initiation.
