Norethindrone (C0028356)

Definition (NCI) A synthetic progestational substance with some anabolic, estrogenic, and androgenic properties. Norethindrone binds to the progesterone intracellular receptors in the reproductive system and the resultant activated complex interacts with specific DNA sites. This leads to an alteration in protein synthesis and results in an inhibition of LH release. Consequently, it inhibits ovulation and changes the normal cycle of cervical mucus and endometrium.
Definition (MSH) A synthetic progestational hormone with actions similar to those of PROGESTERONE but functioning as a more potent inhibitor of ovulation. It has weak estrogenic and androgenic properties. The hormone has been used in treating amenorrhea, functional uterine bleeding, endometriosis, and for contraception.
Definition (CSP) synthetic progestational hormone with actions similar to those of progesterone but functioning as a more potent inhibitor of ovulation; has weak estrogenic and androgenic properties; has been used in treating amenorrhea, functional uterine bleeding, endometriosis, and for contraception.
