Introduction

Ethinyl estradiol, also sometimes written as ethinylestradiol, ethynyl estradiol, or ethinyl œstradiol, is a derivative of 17β-estradiol(E2), the major endogenousestrogen 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 17 beta 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.

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.

The major concern with unopposed estrogen is of endometrial cancer. The medication is generally prescribed withprogesterone in the setting of birth control.
