Uses It belongs to estrogen drug. It can be used for treating leukopenia, various kinds of menopathy, senile vaginitis, and menopausal syndrome. You may also get temporary breast swelling and lumps, menstrual cycle disorders with self-recovery after stopping the drug for about 1 month. Patients of breast hyperplasia, breast lumps, and cancer potentially being related to female hormone-related cancer, aplastic anemia and liver disease patients should be disabled.

 

Estriol can be a weak or strong estrogen depending on if it is given acutely or chronically when given to immature animals, but is an antagonist when given in combination with estradiol. Estriol may play a role in the development of breast cancer, but based on in vitro research, does appear to act as an antagonist to the G-protein coupled estrogen receptor. Though estriol is used as part of the primarily North American phenomenon of bioidentical hormone replacement therapy, it is not approved for use by the FDAor Health Canada. Though initial research in the 1970s suggested it could be used therapeutically as an estrogen, subsequent research failed to confirm this hypothesis.
