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, sau un progestativ sintetic, și, prin urmare, este un agonist al receptorului de progesteron, the biological target of progestogens like progesterone.It has no androgenic activity.
Norgesterone is used to prevent pregnancy. It is often referred to as the "mini-pill" because it does not contain any estrogen. Norgestrel (a form of progestin) is a hormone that prevents pregnancy by making vaginal fluid thicker to help prevent sperm from reaching an egg (fertilization), and changing the lining of the uterus (womb) to prevent attachment of a fertilized egg.
