Description:

 

1. 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.

2. 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 FDA or Health Canada.Though initial research in the 1970s suggested it could be used therapeutically as an estrogen,subsequent research failed to confirm this hypothesis.In pregnant women with multiple sclerosis, estriol reduces the disease's symptoms noticeably, according to researchers at UCLA's Geffen Medical School.

Application:

 

1 . Hormonal contraception:A chemical derivative of estradiol, ethinyl estradiol with maximum dosage 200

 

µg, is a major component of hormonal contraceptive devices. Combined forms of hormonal contraception

 

contain ethinyl estradiol and a progestin, which both contribute to the inhibition of GnRH, LH, and FSH,

 

which accounts for the ability of these birth control methods to prevent ovulation and thus prevent

 

pregnancy. Other types of hormonal birth control contain only progestins and no ethinyl estradiol.

 

2 . Hormone replacement therapy:If severe side effects of low levels of estradiol in a woman's blood are

 

experienced (commonly at the beginning of menopause or after oophorectomy), hormone replacement

 

therapy may be prescribed. Such therapy is usually combined with a progestin to reduce the risk of

 

endometrial cancer.Estrogen therapy may be used in treatment of infertility in women when there is a

 

need to develop sperm-friendly cervical mucus or an appropriate uterine lining. This is often prescribed in

 

combination with clomifene.

 

3 . Estrogen therapy can also be used to treat advanced prostate cancer, as well as to relieve symptoms

 

of breast cancer.Not all products are available worldwide. Estradiol is also part of conjugated estrogen

 

preparations, such as Premarin, though it is not the major ingredient. (Premarin consists of a large

 

number of estrogen derivatives. As the name indicates, it comes from pregnant mares' urine.
