Abstract

The invention discloses an axitinib tablet and a preparation method thereof. The preparation method comprises the following steps: controlling crystallization process so as to obtain an axitinib-mesoporous silica compound, then mixing the axitinib-mesoporous silica compound with a filler and a disintegrating agent, carrying out granulation and drying, adding a lubricant into dry particles and then carrying out tableting. Compared with the prior art, the axitinib tablet prepared in the invention can be rapidly dissolved out in water, and the preparation method is simple in process and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to an axitinib tablet and a preparation method thereof. Background technique [0002] Axitinib was approved by the FDA on January 27, 2012, for the treatment of advanced renal cell carcinoma (Renal Cell Carcinoma, RCC) ineffective by other systemic treatments. Axitinib was developed by Pfizer with the trade name Inlyta. Similar to Sunitinib, another anticancer drug of Pfizer, axitinib is also a multi-target tyrosine kinase inhibitor, which can inhibit the vascular endothelial cell growth factor receptors VEGFR1, VEGFR2, VEGFR3, platelet-derived growth Factor receptors and c-KIT. [0003] The chemical name of axitinib is N-methyl-2-[[3-[(1E)-2-(2-pyridyl)vinyl]-1H-indazol-6-yl]thio]-benzo Amide, the structural formula is as follows: [0004] [0005] Molecular formula: C 22 h 18 N 4 OS, molecular weight: 386.47 [0006] Axitinib is a white to slightly yellow p...
