Norethindrone acetate
Norethindrone Acetate
Norethindrone Acetate (pronunciation: nor-ETH-in-drone AS-e-tate) is a synthetic progestational hormone with actions similar to those of progesterone but functioning as a more potent inhibitor of ovulation. It has weak estrogenic and androgenic properties. The acetate is administered orally.
Etymology
The term "Norethindrone" is derived from the chemical name 17α-ethynyl-19-nortestosterone. The "Acetate" part refers to the acetic acid ester that is formed during the process of esterification.
Pharmacology
Norethindrone Acetate is used for the prevention of pregnancy in women who elect to use this product as a method of contraception. It is also used for the treatment of secondary amenorrhea, endometriosis, and abnormal uterine bleeding due to hormonal imbalance in the absence of organic pathology, such as fibroids or uterine cancer.
