Some women find that taking an oral contraceptive that contains the older progestin called norethindrone at a dose of 1.5 nanograms helps restore the proper balance for libido. ❋ M.D. Valerie Davis Raskin (2002)
She also tries different hormones, such as norethindrone, a type of progesterone more commonly used in Europe. ❋ Unknown (2009)
Even today, norethindrone, though not norethynodrel, is still used by millions of women as an oral contraceptive. ❋ Unknown (2010)
One and one-half years after the first publication by the Syntex group, chemists at G.D. Searle -- a company for which Pincus consulted, synthesized a close relative, norethynodrel, which, as shown by Pincus -- is largely converted in the stomach into norethindrone. ❋ Unknown (2010)
Mexican pharmaceutical company, Syntex, S.A., first synthesized an orally active progestational steroid, named norethindrone, which does not exist in nature and that they supplied Pincus with this steroid for further biological work. ❋ Unknown (2010)
Both Syntex's norethindrone and Searle's norethynodrel were approved in 1957 by the FDA for the treatment of menstrual disorders. ❋ Unknown (2010)

Only two years later, on October 15, 1951, the group led by the then 28-year-old Djerassi, had synthesized norethindrone, a "super-potent orally active progestational agent", which turned out to be the key ingredient in The Pill. ❋ Unknown (2008)
None of Pincus's and Rock's work would have been possible without the initial chemical breakthrough in Mexico on deliberately synthesizing an orally effective progestin -- an achievement which was recognized by the National Medal of Science in 1973 in the White House and in 1978 by inclusion of Syntex's norethindrone as the first ever drug in the ❋ Unknown (2010)
On October 21, 2010, the FDA approved, LO LOESTRIN FE norethindrone acetate and ethinyl estradiol tablets, ethinyl estradiol tablets and ferrous fumarate tablets, our new oral contraceptive product for the prevention of pregnancy in the United States.
The drug is a birth control pill comprised of norethindrone and ethinyl estradiol, and comes with ferrous fumarate tablets. ❋ MarketNewsVideo.com (2011)
The 2011 revenue expectations reflect, among other things, the expected impact of the loss of exclusivity of ACTONEL (risedronate sodium tablets) in Western European markets as well as the anticipated growth of promoted products in the U.S., including two products launched in early January - ATELVIA (risedronate sodium delayed release tablets) and LO LOESTRIN FE (norethindrone acetate and ethinyl estradiol tablets, ethinyl estradiol tablets and ferrous fumarate tablets).
His team later synthesized norethindrone - a progestin-analogue that was effective when taken orally. ❋ Unknown (2010)
