[0033] Preparation of Example 1-7 and Comparative Example 1-4 Regorafenib Solid Dispersion

Embodiment 1-7

[0034] Example 1-7 The composition of regorafenib solid dispersion is shown in the table below:

[0035]

Embodiment 1

[0038] Example 1 Preparation of regorafenib solid dispersion:

[0039](1) Dissolving regorafenib in absolute ethanol to make a solution with a concentration of 20% (m / v) for subsequent use;

[0040] (2) get sorbitol to be dissolved in water, make the solution that concentration is 35% (m / v), for subsequent use;

[0041] (3) Under stirring conditions, add the sorbitol aqueous solution to the regorafenib ethanol solution, stir for 10 min, then add the pre-dissolved povidone ethanol solution with a concentration of 15% (m / v), and continue stirring for 3 min , Concentrate the solution to dryness under reduced pressure with a rotary evaporator, transfer the product to a vacuum drying oven, and continue drying at room temperature for 24 hours to obtain the product.

Abstract

The invention discloses a regorafenib solid dispersion, which comprises regorafenib, a carrier material and a synergistic agent in the mass ratio of 1: (2-20): (0.2-5), the carrier material comprises povidone and sorbitol in the mass ratio of 1: (0.1-0.5), and the synergistic agent comprises silica and Docusate sodium in the mass ratio of 1: (0.5-1). Through a certain process, the regorafenib is prepared into the sorbitol-regorafenib-povidone sandwich structure solid dispersion, dissolution of the regorafenib from inside to outside is promoted, the solubility of the regorafenib is greatly improved, safe, non-toxic and volatile ethanol is used as a solvent in the preparation process, and no security risk is caused by residual solvent. At the same time, the aging phenomenon in the long time storage process of the regorafenib solid dispersion can be avoided, and stability is improved.
