Norethindrone acetate

Overview:

Norethindrone acetate
(when available)

Pharmacology and use:
Norethindrone is a synthetic oral progestin. It is used for contraception or to treat such conditions as secondary amenorrhea, abnormal uterine bleeding, and endometriosis. As an oral contraceptive, norethindrone is available as either a single agent or in combination with an estrogen. For use as an oral contraceptive in the prevention of pregnancy.

Mechanism Of Action:
Progestins diffuse freely into target cells and bind to the progesterone receptor. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. Once bound to the receptor, progestins slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH surge.
