Goserelin acetate is a synthetic decapeptide analogue of gonadotropin releasing hormone agonist dispersed for continuous release in a matrix of D,L-lactic and glycolic acids copolymer that is completely biodegradable with no demonstrable antigenic potential.  Goserelin inhibits pituitary gonadotropin secretion as the implant degrades, following an initial increase in serum luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels and subsequent testosterone levels in males.  Gradually the levels taper off to suppression with suppression of pituitary gonadotropins with levels of testosterone falling into the range normally seen in surgically castrated men within about two weeks of initiation of therapy.

In women, a similar down-regulation of the pituitary gland on gonadotropin secretion is generally seen.  Serum estradiol is suppressed to postmenopausal state within 3 weeks of initiating therapy, however certain individuals may experience isolated elevation of extradiol and suppression of FSH and LH hormone levels may not be attained in some females.
