Product Detail

Mechanism:

Leuprolide is a synthetic nonapeptide analogue of gonadotropin-releasing hormone. Leuprolide binds to, and activates, GnRH / LHRH receptors. In males, Luteinizing hormone and follicle-stimulating hormone release from the anterior pituitary transiently increases testosterone concentration. However, continuous, prolonged administration of leuprolide in males results in pituitary GnRH receptor desensitization and inhibition of pituitary secretion of follicle stimulating hormone (FSH) and luteinizing hormone (LH), leading to a significant decline in testosterone production. It reduces testosterone production to castration levels (medical castration) and usually inhibits androgen receptor-positive tumor progression.
In females, Gonadotropin release from the anterior pituitary transiently increases estrone and estradiol concentrations. However, continuous, prolonged administration results in a decrease in estrogens to postmenopausal levels, leading to inhibition of estrogen-dependent cancers. In the treatment of endometriosis, as a consequence of suppression of ovarian function, both normal and ectopic endometrial tissues become inactive and atrophic. As a result, amenorrhea occurs.

Application:

Leuprolide, also known as Leuprorelin, is a synthetic 9-residue peptide analog of gonadotropin releasing hormone (GnRH) or leutenizing hormone releasing hormone (LHRH). Leuprolide/ Leuprorelin may be used in the treatment of hormone-responsive cancers such as prostate cancer and breast cancer. It may also be used for estrogen-dependent conditions such as endometriosis or uterine fibroids. It may be used for precocious puberty in both males and females, and to prevent premature ovulation in cycles of controlled ovarian stimulation for in vitro fertilization (IVF).
