Hi,
Progesterone is a female sex hormone produced by the
corpus luteum in the ovary following ovulation each month.
It helps thicken the lining of the uterus to prepare for a fertilized egg and thus maintain the menstrual cycle and early stages of
pregnancy.
Primolut-N (
Norethisterone) is a synthetic and potent progesterone hormone that stops
uterine bleeding.
At the time before a period, the level of progesterone falls and this causes the lining of the uterus to be shed as menstrual period.
By taking Primolut-N tablets the levels of progesterone are kept artificially high, and so the period does not start and the period gets delayed.
Primolut-N is also helpful in inducing (starting) the period by taking it at particular days throughout the cycle. Period will start two or three days after you stop taking the drug.
So, it mimics like the natural female sex hormone progesterone and manipulates or modifies its action as explained above.
Hope I have answered your query. Let me know if I can assist you further.
Take care
