Abstract[English]
Provided are novel carbamate fumarate, a crystalline form and amorphous form thereof, and a preparation method therefor. The carbamate fumarate and the crystalline form and amorphous form thereof have high stability and high solubility, low hygroscopicity, and improved pharmaceutical properties, and achieves a better anti-platelet aggregation effect and higher efficacy, thereby facilitating the clinical application of drugs.[French]
L'invention concerne un nouveau fumarate de carbamate, une forme cristalline et une forme amorphe de celui-ci, ainsi qu'un procédé de préparation. Le fumarate de carbamate et sa forme cristalline et sa forme amorphe ont une stabilité élevée et une solubilité élevée, une faible hygroscopicité et des propriétés pharmaceutiques améliorées, et permet d'obtenir un meilleur effet d'agrégation antiplaquettaire et une efficacité supérieure, ce qui facilite l'application clinique de médicaments.[Chinese]
