MELOXICAM CO-CRYSTALS

MELOXICAM CO-CRYSTALS

Co-crystals of meloxicam co-formers can be prepared by co-crystallization from a polar solvent, such as aqueous dimethyl sulfoxide; or by slurry processes, such as with ethyl acetate. Such co-crystals have improved purities and are physically stable under storage for several months. Des co-cristaux...

Zusammenfassung:Co-crystals of meloxicam co-formers can be prepared by co-crystallization from a polar solvent, such as aqueous dimethyl sulfoxide; or by slurry processes, such as with ethyl acetate. Such co-crystals have improved purities and are physically stable under storage for several months. Des co-cristaux d'agents de co-formation de méloxicam peuvent être préparés par co-cristallisation à partir d'un solvant polaire, tel qu'un sulfoxyde de diméthyle aqueux; ou par des procédés en suspension, par exemple avec de l'acétate d'éthyle. De tels co-cristaux ont des puretés améliorées et sont physiquement stables pendant plusieurs mois.
