Abstract:
A novel solid form of Rosuvastatin comprises as the active ingredient a salt of bis[(E)-7-[4-(4-fluorophenyl)-6-isopropyl-2-[methyl(methylsulfonyl)-amino]pyrimidin-5-yl]-(3R,5S)-3,5-dihydroxyhept-6-enoic acid] and vanillin or vanillin derivatives. The crystal comprising the two components, and minor amounts of water, shows improved properties such as crystallization behavior stability and decreased hydroscopic behavior.
Abstract:
Combinations of (3β)-17-(pyridin-3-yl)androsta-5,16-dien-3-yl acetate (Abiraterone acetate) with acidic substances such as citric acid, ascorbic acid, methyl-4-hydroxy benzoate, saccharin, vanillic acid, adipic acid, maleic acid, malic acid, tartaric acidare useful as pharmaceutical preparations and show improved properties such as aqueous solubility and dissolution kinetics, especially in the form of cocrystals or their combination with a suitable acid.
