Pharmacological effects:
Norethinnes is a derivative of 19-methyltestosterone, an oral progesterone. The activity of progesterone was 4 times higher than that of parneprogesterone, and the activity of estrogen and androgen was weaker. It can inhibit the secretion of hypothalamic luteinizing hormone (LHRH), and stimulate the anterior pituitary to reduce the body's sensitivity to LHRH, so as to block the release of gonadotropin and inhibit ovulation. The peak blood concentration can be reached after 0.5 ~ 4 hours of oral administration, with a half-life of 5 ~ 14 hours. Most of the metabolites are excreted from the body through the kidneys.
 
USES:
Norethinnes is a 19- methylated testosterone derivative. It is a strong oral progesterone with mild androgen and estrogen activity. It can block the release of gonadotropin, inhibit ovulation and maintain pregnancy. Used for oral contraception, functional uterine bleeding, endometriosis, female infertility, dysmenorrhea, amenorrhea, etc.
