Mechanism of Action (MOA)
The key ingredient of Duphaston is dydrogesterone (10 mg). The MOA of this medicine is that it inhibits the growth of endometrium. This endometrium which is naturally produced progesterone is often produced by the ovaries at the menstrual cycle’s second phase.
Consequently, this makes the endometrium, which in response to estrogen, thickened in the first half of the cycle. This is done in order to inhibit growing and then start producing hormones and other proteins necessary for maintenance of the pregnancy, in case conception occurs. If this does not happen, the levels of progesterone and estrogen fall. This leads to the shedding of endometrium (menstruation).
The action of the dydrogesterone within the Duphaston will help in re-establishing a regular menstrual cycle. This is especially so in environments where there is insufficient endogenous progesterone that leads to menstrual problems. For instance, in the abdominal bleeding of the uterus and secondary amenorrhea and facilitates the treatment of the miscarriage (spontaneous abortion). It further treats infertility by stimulating endometrium so as to prepare for pregnancy and protect the existing pregnancy.
Indeed, Duphaston acts on endometrium in all its locations. This helps to inhibit its growth, thereby alleviating the symptoms related to endometriosis including bleeding and pain.
