Duphaston Tablet 10 mg

Duphaston Tablet 10 mg Uses, Dosage, Side Effects, Food Interaction and all others data.

Duphaston Tablet 10 mg is a progestogen structurally related to progesterone. However, unlike progesterone, it does not induce an increase in temp nor inhibit ovulation and may be preferred over other progestational agents when contraceptive effect is not required. It does not have oestrogenic or androgenic properties.

Duphaston Tablet 10 mg is an orally active progestogen which acts directly on the uterus, producing a complete secretory endometrium in an estrogen-primed uterus. At therapeutic levels, dydrogesterone has no contraceptive effect as it does not inhibit or interfere with ovulation or the corpus luteum. Furthermore, dydrogesterone is non-androgenic, non-estrogenic, non-corticoid, non-anabolic and is not excreted as pregnanediol. Duphaston Tablet 10 mg 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.
