Leuproreline

Leuprolide Human Synthetic is a single, non-glycosylated, polypeptide chain containing 9 amino acids and having a molecular mass of 1209 Dalton. The molecular formula is C59H84N16O12. Leuprorelin (INN) or leuprolide acetate (USAN) is a gonadotropin-releasing hormone agonist (GnRH agonist) .By causing constant stimulation of the pituitaryGnRH receptors, it initially causes stimulation (flare), but thereafter decreases pituitary secretion (downregulation) of gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH) .Like other GnRH agonists, leuprolide may be used in the treatment of hormone-responsive cancers such as prostate canceror breast cancer, estrogen-dependent conditions (such as endometriosisor uterine fibroids), to treat precocious puberty, and to control ovarian stimulation in IVF.

Greater than 98.0% as determined by RP-HPLC.

The Leuprorelin was lyophilized from a concentrated (1 mg/mL) solution with no additives.

Lyophilized Leoprolide although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Leuprorelin should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA) .Please prevent freeze-thaw cycles.

It is recommended to reconstitute the lyophilized Leoprolide in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
