Norethisterone

Norethisterone (NET) is a synthetic progestogen used in hormonal contraceptives and for treating certain menstrual problems. It is a synthetic hormone closely related to progesterone and acts by preventing ovulation and/or suppressing the effects of estrogen on target tissues.

Uses For

Norethisterone is used in combination with estrogen-containing products to regulate the menstrual cycle and to treat menopausal symptoms. It has also been used to manage certain menstrual conditions, such as endometriosis, premenstrual syndrome, and abnormally heavy bleeding.

Mechanism of Action

Norethisterone binds to progesterone receptors in the body, thereby blocking the effect of the estrogen on target tissues. It also suppresses the activity of the hypothalamic–pituitary–ovarian axis, preventing the release of gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH), which is necessary for ovulation.

How Long Does It Take to Work?

Norethisterone usually begins to work within a few hours of taking it. If taken with estrogen, it generally takes a few days for the full hormonal effect to be achieved.

Absorption

Norethisterone is readily absorbed via the gastrointestinal tract after oral administration, but its bioavailability can be decreased somewhat when taken concomitantly with certain food and medicines.

Route of Elimination

Norethisterone is primarily metabolized in the liver and excreted in the urine. Its metabolites are eliminated via the bile.

Dosage

The dosage of norethisterone to treat menstrual conditions should be determined by a health care provider. Typical dosages range from 1-5mg taken daily for the duration of the treatment regimen.

Administration

It should only be used when medically indicated and under the close supervision of a health care provider.
