Abstract

The invention discloses ticagrelor tablets and a preparation method thereof and belongs to the technical field of medicines. According to the ticagrelor tablets disclosed by the invention, mannitol, microcrystalline cellulose, low-substituted hydroxypropyl cellulose, croscarmellose sodium and magnesium stearate are selected as auxiliary materials and are compounded with the raw material medicine ticagrelor tablets so as to obtain the ticagrelor tablets, and each auxiliary material and the raw material medicine are synergetic in the defined amount range, so that the dissolution rate of the prepared ticagrelor tablets is higher than that of the conventional commercially available tablets. Moreover, the ticagrelor tablets have the same dissolution behavior as the commercially available medicines, the ticagrelor tablets have good absorption effects, and the bioavailability of the ticagrelor tablets is improved. The ticagrelor tablets disclosed by the invention are small in impurity content and are stable in performance under high-temperature illumination conditions. The method for preparing the ticagrelor tablets disclosed by the invention is simple in process flow, easy to operate and implement and suitable for industrial popularization and application.
