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, или синтетический прогестаген, и, следовательно, является агонистом рецептора прогестерона., the biological target of progestogens like progesterone.It has no androgenic activity.
Norgesterone is used to prevent pregnancy. Его часто называют "мини-таблетка" потому что он не содержит эстрогена. Норгестрел (форма прогестина) is a hormone that prevents pregnancy by making vaginal fluid thicker to help prevent sperm from reaching an egg (оплодотворение), and changing the lining of the uterus (матка) to prevent attachment of a fertilized egg.
