| Hazard Information | Back Directory | [Description]
Gestrinone is a synthetic steroid with antiprogesterone and antiestrogenic activities.
It is reported to be useful in the treatment of endometriosis and uterine leiom yomas. | [Chemical Properties]
Light Yellow Solid | [Originator]

ChEBI: Gestrinone is an oxo steroid. | [Brand name]
DIMETROSE | [Side effects]
Gestrinone, like danazol, inhibits the synthesis of estrogens and progestogens and has been used mainly to prepare patients with an endometrial disorder for hysterectomy. Its most common adverse effects are nausea, headache, mood changes, rash, hot flushes, weight gain, and discomfort in the joints and muscles. In some cases, there is evidence of masculinization. | [Mode of action]
The primary action of gestrinone is on the hypothalamic-pituitary axis, where it inhibits gonadotrophin release with a weak inhibitory effect on its synthesis. It also possesses anti-estrogen activity. The mode of action of gestrinone used for EC is probably inhibition of implantation by acting on the endometrium rather than inhibiting ovulation[1].
