Goserelin. A review of its pharmacodynamic and pharmacokinetic properties, and therapeutic use in benign gynaecological disorders.

Abstract：

:Goserelin is a gonadotrophin-releasing hormone (GnRH) analogue which, during continuous administration, down-regulates the pituitary-ovarian gonadal axis and reduces levels of the gonadotrophins, luteinising hormone and follicle-stimulating hormone. In women, this results in suppression of ovarian steroidogenesis and a decline in estrogen to levels similar to those observed after menopause or following surgical oophorectomy. Thus, goserelin has a useful role in the management of some benign estrogen-dependent gynaecological disorders. Goserelin is available as a biodegradable sustained release depot 3.6mg injection which is administered every 28 days. In women with endometriosis, monthly injections of depot goserelin were effective in achieving resolution of endometriotic implants and in improving pelvic symptoms, including pain and dyspareunia. Randomised clinical comparisons of depot goserelin with danazol indicate that goserelin is at least as effective as danazol and is better tolerated in the treatment of endometriosis. In the management of uterine leiomyomata (fibroids), goserelin depot injections reduce uterine size and the size of uterine leiomyomata, with maximum clinical benefit achieved approximately 3 to 4 months after initiation of treatment. When used as an adjunctive pretreatment for women undergoing surgical removal of uterine leiomyomata, goserelin was associated with technically easier surgical procedures, reduced intraoperative blood loss and reduced transfusion requirements around the time of surgery. As an alternative to surgery, therapeutic use of goserelin is limited by the rapid regrowth of leiomyomata following cessation of treatment. However, goserelin may be a useful treatment for women approaching menopause, in whom uterine leiomyomata shrink naturally as endogenous estrogen levels decline. In women with dysfunctional uterine bleeding, treatment with depot goserelin before surgery facilitates resection and ablative procedures by suppressing endometrial growth and thinning the endometrial mucosa. Goserelin is also an effective alternative to surgery in this patient group. As adjuvant therapy for women undergoing assisted reproduction procedures, goserelin is associated with reduced cycle cancellation rates and with an increase in the rate of oocyte retrieval. The tolerability profile of goserelin is characterised by adverse effects typical of hypoestrogenism, including hot flushes, loss of libido and loss of bone mineral density. However, concomitant 'add-back' hormone replacement therapy appears to effectively reduce these hypoestrogenic symptoms. In summary, the availability of depot goserelin has broadened the spectrum of effective treatments for benign estrogen-dependent gynaecological disorders. As goserelin is effective as a sustained release depot formulation suitable for administration on a monthly basis, it is also a convenient and practical treatment choice.
