Abstract: The present invention relates to drug delivery systems in the form of thin water-soluble films (wafers), which contain an Estrogen Receptor beta (ER-?) selective agonist. The wafers of the present invention are suitable for treating, alleviating or preventing a physical condition in a female mammal caused by insufficient endogenous levels of estrogen.

Abstract: The present invention relates to drug delivery systems in the form of thin water-soluble films (wafers), which contain estradiol, or derivatives thereof, in low amounts.

Abstract: A combination of an anti-androgenic gestagen at a daily dose of from an ovulation-inhibiting dose up to at most twice the ovulation-inhibiting dose and from 0.1 to 10 mg of (6S)-5-methyltetrahydrofolate are used to produce a pharmaceutical preparation for therapeutically treating endometriosis while simultaneously reducing therapy side effects including the negative effect on bone density and/or bone metabolism, reducing the risk of osteoporosis and, in the event of pregnancy, reducing the risk of congenital malformations, such as medullary tube defects, cleft lip, cleft jaw, or cleft palate, and the risk of pregnancy complications, such as detachment of the placenta and premature birth. The preparation is suitable for long-term administration, which continues daily for at least 169 days to at least two years.
