Answer

GnRH agonists

Work by reducing concentration of GnRH receptors in the pituitary via receptor down regulation and induction of postreceptor effects, which suppress gonadotropin release. After an initial gonadotropin release associated with rising estradiol levels, gonadotropin levels fall to castrate levels, with resultant hypogonadism. This form of medical castration is very effective in inducing amenorrhea, thus breaking ongoing cycle of abnormal bleeding in many anovulatory patients. Because prolonged therapy with this form of medical castration is associated with osteoporosis and other postmenopausal side effects, its use is often limited in duration and add back therapy with a form of low-dose hormonal replacement is given. Because of the expense of these drugs, they usually are not used as a first line approach but can be used to achieve short-term relief from a bleeding problem, particularly in patients with renal failure or blood dyscrasia.

Depot leuprolide acetate (Lupron)

Suppresses ovarian steroidogenesis by decreasing LH and FSH levels.
