The present invention relates to the field of pharmaceutical technology and describes a novel advantageous preparation for an active ingredient. The novel preparation is suitable for producing a large number of pharmaceutical dosage forms. In the new preparation an active ingredient is present essentially uniformly dispersed in an excipient matrix composed of one or more excipients selected from the group of fatty alcohol, triglyceride, partial glyceride and fatty acid ester.
derivatives of the highly active aldosteroneantagonists dihydrospirorenone (2) and spirorenone (3) were synthesized. The purpose of these efforts was to prepare compounds exhibiting reduced endocrinological properties with the same or better aldosteroneantagonistic activity than that of spirorenone. The 1 alpha,2 alpha-methylene derivative 20 has a similar aldosteroneantagonistic potency compared to that
