4.1 Therapeutic indications

For the treatment of advanced hormone dependent prostatic carcinoma (stage C or stage D according to the classification of Murphy et al. in Cancer, 45, p 1889-95, 1980) in which suppression of testosterone is indicated; however, not after bilateral orchiectomy (no further reduction of testosterone level by buserelin to be expected).

Buserelin acts by blockade and subsequent down-regulation of pituitary LHRH receptor synthesis. Gonadotropin release is consequently inhibited. As a result of this inhibition there is reduced stimulation of testosterone secretion and serum testosterone levels fall to the castration range. Before inhibition occurs there is a brief stimulatory phase during which testosterone levels may rise.
