    Abstract: The method of isolating an anhydrous etidronate disodium particulate includes preparing a liquid-liquid dispersion consisting of an aqueous-organic phase and an etidronate-disodium-salt-containing aqueous phase; adjusting a temperature of the liquid-liquid dispersion to between 0 and 30° C. and intensely agitating so that a coarse-particle fraction precipitates from the liquid-liquid dispersion, then drawing off a fine-particle suspension and allowing a fine-particle fraction to precipitate from it and filtering and drying the coarse particle fraction. In a preferred embodiment the fine-particle fraction is separated from the fine-particle suspension for recycling The resulting anhydrous etidronate disodium particulate has a grain size of from about 0.1 to 1 mm and a bulk density of 0.4 to 0.6 g/cm2 with good properties for pharmaceutical applications.

    Abstract: The solid peroral contraceptive contains an effective ingredient combination of dienogest in a daily dosage of equal to or less than 2.0 mg and ethinyl estradiol in a daily dosage of less than 0.03 mg together with one or more pharmaceutically acceptable carriers. The dienogest is released in two stages, while the ethinyl estradiol is released with the first stage portion of the dienogest.
