The Many Uses for Ethinyl Estradiol

Ethinyl EstradiolEthinyl Estradiol, CAS# 57-63-6 is a widely used oral estrogen that can be found in most contraceptive products. The patent for Ortho Evra, which combines is ethinyl estradiol and norelgestromin is set to expire on November 20, 2015. Janssen markets the successful Ortho Evra patch, and the upcoming patent expiration is foreseen as an opportunity for the development of generic equivalents for this profitable product. As a form of birth control primarily, Ortho Evra is effectively a small skin patch with the same hormones as in oral birth control medications. Deemed 99% effective when used correctly, the birth control patch is worn for one week and then replaced on the same day of the week for three consecutive weeks. The fourth week is a patch-free week, as this is the week designated for the menses to occur. Side effects may include headache, rash at the patch site, cramping, nausea and breast tenderness. The convenience of the once weekly patch is ideal for many women, as today’s busy mom and wife needs a birth control to fit her busy lifestyle. Ten years ago Time Magazine named this birth control patch one of 2002’s “coolest inventions”, and profits have soared for the combination of this ethinyl estradiol and norelgestromin product since then.

Birth control is a primary method of delivery for ethinyl estradiol, either in the patch or pill formulation, but it is not it’s only use. Women experiencing menopause are often dosed with this female hormone and it is usually given to women who no longer produce the amount of estrogen they produced before menopause. Ethinyl estradiol is a very effective treatment for reducing common menopausal symptoms, such as hot flashes and bone loss.
