DRUG CLASS AND MECHANISM:
Norethindrone is a progestin that is used as an
oral contraceptive. Progestins prevent pregnancy by inhibiting
(release of the egg), making it more difficult for sperm to penetrate the
uterine mucus that surrounds the egg, and therefore, for
fertilization to take
place. Progestins also change the uterine lining to prevent the fertilized egg
from implanting in the uterus.
