DescriptionBuserelin is a luteinizing hormone-releasing hormone (LHRH) agonist. It is a synthetic hormone which stimulates the pituitary gland's gonadotrophin-releasing hormone receptor (GnRHR) and is used in prostate cancer treatment.
Indication/DiseaseBuserelin may be used in the treatment of hormone-responsive cancers such as prostate cancer or breast cancer, estrogen-dependent conditions (such as endometriosis or uterine fibroids), and in assisted reproduction.
PharmacodynamicsN.A.
Mechanism of ActionBuserelin stimulates the pituitary gland's gonadotrophin-releasing hormone receptor (GnRHR). Buserelin desensitizes the GnRH receptor, reducing the amount of LH and testosterone. However, there is a concomitant surge in LH and testosterone levels with the decrease in androgens, so antiandrogens must administered.
