Description

Menstrone is a synthetic progestogen and has a similar action to the female hormone, progesterone. It is used to treat menstrual disorders in women caused due to a lack of hormones. It is also used to reduce the risk of miscarriages or abortions.

Mechanism of action

Menstrone is an orally active progestogen which acts directly on the uterus, producing a complete secretory endometrium in an estrogen-primed uterus. At therapeutic levels, Menstrone has no contraceptive effect as it does not inhibit or interfere with ovulation or the corpus luteum. Furthermore, Menstrone is non-androgenic, non-estrogenic, non-corticoid, non-anabolic and is not excreted as pregnanediol. Menstrone helps to regulate the healthy growth and normal shedding of the uterus lining. Therefore, it may be useful in the treatment of menstrual disorders such as absent, irregular or painful menstrual periods, infertility, premenstrual syndrome and endometriosis.

Pharmacokinetics

Absorption: Rapidly absorbed in the gastrointestinal tract with a bioavailability of 28%. Distribution: After intravenous administration of Menstrone the steady-state distribution volume is around 1400 L. More than 90% of Menstrone and DHD are bound to plasma-proteins.

Metabolism: Metabolism is complete to a 20-dihydrodydrogesterone (DHD) metabolite. Elimination: After oral administration of labelled Menstrone on average 63% of the dose is excreted in the urine. The total plasma clearance is 6.41/minute. Within 72 hours the excretion is complete, DHD is present in the urine mainly as the conjugated glucuronic acid.

If breakthrough bleeding or spotting appears after some time on therapy, or continues after treatment should be discontinued & reason should be investigated, if necessary by endometrial biopsy to exclude endometrial malignancy.

Adverse Reactions

The most commonly reported adverse drug reactions of patients treated with Menstrone in clinical trials of indications without oestrogen treatment are migraines / headache, nausea, menstrual disorders and breast pain/tenderness.

Pregnancy and Lactation

It is estimated that altogether roughly 35 million women have been treated with Menstrone. From spontaneous surveillance systems to date, there is no evidence that Menstrone cannot be used during pregnancy. No other relevant epidemiological data on Menstrone are available.

There is no evidence that Menstrone decreases fertility. Menstrone is excreted in the milk of nursing mothers. A risk to the suckling child cannot be excluded. Menstrone should not be used during breast-feeding.
