Leuprorelin (leuprolide acetate) is a synthetic analogue of gonadotrophin-releasing hormone (GnRH) [luteinising hormone-releasing hormone (LHRH)] which initially stimulates luteinising hormone (LH) and hence testicular androgen release; continuous administration then results in profound suppression of these hormones. Testosterone levels associated with castration are attained within 3 to 4 weeks. A biodegradable subcutaneous or intramuscular depot formulation of leuprorelin 3.75 or 7.5 mg, which releases the drug at a constant rate over 28 days, is available and may be preferred over daily subcutaneous injections. The progression of previously untreated advanced prostatic cancer is delayed in 70 to 90% of men receiving leuprorelin, with median survival of approximately 2 years. The efficacy of leuprorelin is equivalent to that of estrogen therapy, but the tolerability of the GnRH analogue is far better. In contrast to most other studies of GnRH agonists, a slight survival advantage has been reported for combined treatment with leuprorelin and the antiandrogen flutamide. Small noncomparative trials reveal that leuprorelin also causes regression of benign hyperplastic prostate tissue with corresponding relief of obstructive, but not irritative, symptoms although continuous treatment is necessary to maintain remission. Impotence and flushing occur in most leuprorelin recipients but, unlike diethylstilbestrol (stilboestrol), cardiovascular toxicity and gynaecomastia are not significant problems. Symptom flare, usually manifested as bone pain in prostate cancer patients and exacerbation of obstructive symptoms in those with benign prostatic hypertrophy, can occur in 4 to 29% at the beginning of treatment. Leuprorelin treatment is therefore an established effective palliative measure in men with previously untreated advanced prostatic cancer, and may have a role in those with benign hypertrophy who are unfit for surgery.
