| | Nestoron Usage And Synthesis |
| Uses | Segesterone Acetate has been used to study the: comparison of androgenic and estrogenic properties of progestins used in contraception and hormone therapy; impact on hepatic estrogen-sensitive proteins by 1-yr contraceptive vaginal ring delivering Nestorone and ethinyl estradiol. | | Definition | ChEBI: Elcometrine is a corticosteroid hormone. | | Pharmacokinetics | Elcometrine is a member of the 19-norprogesterone class of pr ogestins. when administered subcuta neously (implant), intravaginally (vaginal ring), or transdermally, elcometrine is an exceptionally potent progestin. It is 100-fold more potent when administered subcutaneously than when delivered orally. Its oral bioavaiability is only 10%，with a half life of just 1 to 2 hours because of rapid metabolism. The C16 methylene functionality substantially increases its affinity for the progesterone receptor. | | Clinical Use | Because of its antiestrogenic action, elcometrine also can be administered transdermally along with estradiol as a treatment for menopausal symptoms . |
