PHARMACODYNAMIC _Mode of Action/Pharmacodynamic Characteristics _ Pharmaco-therapeutic class: Antineoplastic and immunomodulating agents (L: Gonadotropin releasing hormone analogues). Buserelin is an analogue of the natural gonadotrophin releasing hormone (gonadorelin; GnRH) with enhanced biological activity. After repeated administration of buserelin, the secretion of gonadotrophins and gonadal steroids is significantly inhibited. The pharmacological effect is attributable to the down-regulation of pituitary LH-RH receptors. In male individuals the elimination of gonadotrophin release results in a reduction in the synthesis and secretion of testosterone. In female individuals the elimination of pulsatile gonadotrophin release inhibits the secretion of estrogens. The suppressive effect of buserelin on the secretion of gonadal steroids depends on the daily dose, the frequency of application and the duration of treatment. While gonadotropin release is inhibited during long-term treatment with buserelin, the secretion of the other pituitary hormones (growth hormone, prolactin, ACTH, TSH) is not directly influenced. However, oestrogen deficiency may lead to decreased secretion of growth hormone and prolactin. The secretion of adrenal steroids remains unchan Прочитать полный документ
