Norgesterone, also known as norvinodrel or vinylestrenolone and sold under the brand name Vestalin, is a progestin medication which was formerly used in birth control pills for women but is now no longer marketed. It was used in combination with the estrogen ethinylestradiol.It is taken by mouth.
Norgesterone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.It has no androgenic activity.
Norgesterone is used to prevent pregnancy. Es wird oft als bezeichnet "Minipille" weil es kein Östrogen enthält. Norgestrel (eine Form von Gestagen) is a hormone that prevents pregnancy by making vaginal fluid thicker to help prevent sperm from reaching an egg (Düngung), and changing the lining of the uterus (womb) to prevent attachment of a fertilized egg.
