Description:
Ethinylestradiol is a man-made form of the naturally occurring female hormone called oestrogen. It is prescribed to treat period (menstrual) problems, and also to help ease menopausal symptoms. It is usually prescribed alongside another female hormone called a progestogen.?
Ethinyl estradiol also sometimes written as ethinylestradiol, ethynyl estradiol, or ethinyl? Stradiol, is a derivative of 17β -estradiol (E2), the major endogenous estrogen in humans. EE is an orally bioactive estrogen used in many formulations of combined oral contraceptive pills. It is one of the most commonly used medications for this purpose.?
Estinyl was a preparation of EE alone that was used for the management of menopausal symptoms and female hypogonadism.?
EE is released into the environment as a xenoestrogen from the urine and feces of people who take it as a medication.?
Application:
Ethinyl estradiol?(EE), also sometimes written as?ethinylestradiol,?ethynyl
estradiol, or?ethinyl estradiol, is aderivative?of?17 beta-estradiol?(E2), the major?endogenous?estrogen?in humans. EE is an orally?bioactive?estrogen used in many?formulations?of?combined oral contraceptive pills. It is one of the most
commonly used?medications?for this purpose.
Transdermal ethinyl estradiol carries a greater risk of clot formation and?venous thromboembolism?than naturally occurring?17β-estradiol, which some have theorized
to be related to different amounts of hepatic metabolism after absorption. The same?contraindications?and precautions apply for EE as with other estrogen medications.
