Ethinylestradiol (EE) is a synthetic, steroidal estrogen and a derivative of estradiol, the major endogenous estrogen in humans. It is an estrogen that is active when taken by mouth and is used in almost all formulations of combined birth control pills, and is nearly the exclusive estrogen used for this purpose.
Ethinyl Estradiol is a semisynthetic estrogen. Ethinyl estradiol binds to the estrogen receptor complex and enters the nucleus, activating DNA transcription of genes involved in estrogenic cellular responses. This agent also inhibits 5-alpha reductase in epididymal tissue, which lowers testosterone levels and may delay progression of prostatic cancer. In addition to its antineoplastic effects, ethinyl estradiol protects against osteoporosis. In animal models, short-term therapy with this agent has been shown to provide long-term protection against breast cancer, mimicking the antitumor effects of pregnancy.
Side effects:
the same as for other estrogens and include breast tenderness, headache, fluid retention (bloating), nausea, dizziness, and weight gain.The estrogen component of oral contraceptives, which is almost always EE, can cause breast tenderness and fullness.
