Normethandrone

Normethandrone, also known as methylestrenolone or methylnortestosterone and sold under the brand name Metalutin among others, is a progestin and androgen/anabolic steroid (AAS) medication which is used in combination with an estrogen in the treatment of amenorrhea and menopausal symptoms in women. It is taken by mouth. Side effects of normethandrone include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire. It can also cause liver damage. Normethandrone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It is also a synthetic AAS and hence is an agonist of the androgen receptor, the biological target of androgens like testosterone and dihydrotestosterone (DHT). It has some estrogenic activity as well and no other important hormonal activity. Normethandrone was introduced for medical use by 1957. It is available only in a few countries, including Brazil, Indonesia, and Venezuela, and is available only in combination with methylestradiol or estradiol valerate. Normethandrone is used in combination with an estrogen, either methylestradiol or estradiol valerate, in the treatment of amenorrhea and menopausal symptoms in women. It has also been used to treat dysmenorrhea in women. Normethandrone has been used successfully to inhibit libido in men with sexual deviance. Although normethandrone can be classified as an AAS and has strong such effects at sufficiently high doses, it is not typically used as such and is instead used medically only as a progestin. This is because it is so highly progestogenic in comparison. Normethandrone is marketed in combination with methylestradiol in the form of oral tablets containing 5 mg normethandrone and 0.3 mg methylestradiol.
