Gonadorelin analogues

Further reports of autoimmune thyroid disease in association with gonadorelin analogues have appeared (32). 

The use of gonadorelin analogues is commonly associated with reduced bone mineral density. In 50 premenopausal women with uterine leiomyomas who received leuprolide acetate depot 3.75 mg every 28 days for 18 cycles with raloxifene 60 mg/day, there was a reduction in leiomyoma size with no significant change in bone mineral density or markers of bone metabolism [86],... 

Prostatic cancer is androgen-dependent and metastatic disease can be helped by orchidectomy, or by a gonadorelin analogue, e.g. buserelin, goserelin, leuprorelin or triptorelin. These cause a transient stimulation of luteinising hormone and thus testosterone release, before inhibition occurs some patients may experience exacerbation of tumour effects, e.g. bone pain, spinal cord compression. Where this can be anticipated, prior orchidectomy or antiandrogen treatment, e.g. with cyproterone or flutamide, is protective. 

Repeated attacks are difficult to control. Cyclical premenstrual attacks in women may be prevented by suppression of ovulation with gonadorelin analogues, but most patients require repeated courses of intravenous heme. In one patient with AIP, orthotopic liver transplantation led to...

Spironolactone (p. 534) also has antiandrogen activity and may help hirsutism in women. Androgen secretion may be diminished by continued use of a gonadorelin (LH-RH) analogue (see p. 714). 

Buserelin is an analogue of the hypothalamic hormone, gonadotrophin-releasing hormone (gonadorelin). In chronic use it reduces pituitary secretion of gonadotrophin, which results in reduced secretion of sex hormones by the ovaries or testes. Buserelin is used to treat endometriosis, and also as an anticancer agent for cancer of the prostate gland. It is also used prior to in vitro fertilization. 

U 69689) is a synthetic peptide analogue of gonadorelin (gonadotrophin-releasinghormone), a potent lh-rh RECEPTOR AGONIST with simiiar properties. It can be used in the treatment of gonadal steroid-dependent diseases and infertility in women. For further detail see gonadotrophinreleasing hormone, fertirelin acetate fertirelin.
