Abstract:
Orbit azine-fumarate compounds are provided having the following formula: Different crystal forms of orbit azine-fumarate, an orbit azine-fumarate hydrate and a crystal form thereof, and an amorphous form of orbit azine-fumarate are prepared by adjusting the ratio of orbit azine and fumaric acid and using different crystallization methods. The invention makes it possible to provide an orbit azine-fumarate which has a higher pharmaceutical effect, is easier to prepare, and has improved storage stability.
