Abstract:
The invention relates to the field of pharmaceutical chemistry, particularly relates to an orbit azine-fumarate, a hydrate, a crystal form, and a preparation method therefor. Specifically, in the invention, 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 be prepared, and has a better storage stability.
