Dydrogesterone is a progestogen hormone. The brand name is Duphaston and manufactured by Solvay Pharmaceuticals.
Dydrogesterone was first introduced to the market in 1961, and is currently approved in over 100 countries world-wide. It has an estimated cumulative exposure of more than 28 million patients.
Dydrogesterone is a potent, orally active progestogen indicated in a wide variety of gynaecological conditions. Although similar in molecular structure and pharmacological effects to endogenous progesterone. It is orally active at far lower doses. Its freedom from oestrogenic, androgenic, anabolic, corticoid and other undesirable hormonal effects gives it additional benefits over most other synthetic progestogens. The therapeutic use of dydrogesterone is closely related to its physiological action on the neuro-endocrine control of ovarian function, as well as on the endometrium. As such, it is indicated in all cases of relative or absolute endogeneous progesterone deficiency.
Dydrogesterone has proven effective in the following conditions:
menstrual disorders
infertility
threatened and habitual abortion
endometriosis
premenstrual syndrome
Dydrogesterone has also been registered as hormone replacement therapy (HRT) to counteract the negative effects of unopposed oestrogen on the endometrium. Dydrogesterone is safe and well-tolerated. The incidence of side-effects is remarkably low.
