Norethisterone acetate

Description:

Norethisterone acetate, with the CAS number 51-98-9, is a synthetic progestin, a type of hormone that mimics the effects of progesterone in the body. It is commonly used in hormonal contraceptives and hormone replacement therapy. This compound is characterized by its white to off-white crystalline powder form, which is relatively stable under normal conditions. Norethisterone acetate is lipophilic, allowing it to be absorbed well in the body when administered orally. Its chemical structure includes a steroid backbone, which is essential for its biological activity, and it exhibits anti-estrogenic properties, making it effective in regulating menstrual cycles and managing various gynecological conditions. The substance is typically administered in low doses due to its potency and can have side effects, including changes in mood, weight gain, and potential cardiovascular risks. Overall, norethisterone acetate plays a significant role in reproductive health and is an important compound in the field of endocrinology and gynecology.

Norethindrone acetate

CAS: 51-98-9

Norethindrone acetate is a synthetic estrogen with progestational activity. It is used in combination with an estrogen to treat symptoms of menopause such as hot flashes and vaginal dryness, or in the prevention of endometriosis. Norethindrone acetate is also used in combination with progestin for contraception. It binds to estrogen receptors and produces similar effects to other estrogens, including inhibition of gonadotropin secretion, increased breast size, reduced risk of uterine cancer, and prevention of osteoporosis. The addition of norethisterone acetate provides the benefits of progestogen without the side effect of menstrual bleeding. Norethindrone acetate has been shown to increase serum prolactin levels in women and can cause breast tenderness or enlargement. This drug has been approved by the FDA as a treatment for bowel disease in women when given together with erythromycin. Norethindrone acetate
