Sorry, no etymologies found.
It may also be called norethynodrel with mestranol.
Even today, norethindrone, though not norethynodrel, is still used by millions of women as an oral contraceptive.
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.
Both Syntex's norethindrone and Searle's norethynodrel were approved in 1957 by the FDA for the treatment of menstrual disorders.
