[0010] Edoxaban is a basic compound with good solubility in acidic aqueous solution, but decreased solubility in neutral solution (such as neutral pH6.8 buffer)
The poor dissolution rate of edoxaban in the medium under neutral conditions may also affect the absorption of the drug in the intestine, which will lead to a decrease in bioavailability, which is not conducive to clinical treatment

Abstract
The invention discloses a toluenesulfonic acid edoxaban tablet and a preparation method thereof. Raw materials of the toluenesulfonic acid edoxaban tablet include the following substances by mass: 20.2 parts of toluenesulfonic acid edoxaban, 10.1-101 parts of polymeric carrier, 2.02-10.1 parts of surfactant, 30-45 parts of filler and 0.4-0.8 part of lubricant. The polymeric carrier is preferably amixture of PVP K-30 and HPMCAS with the mass ratio of (2-4):1. The preparation method includes dissolving the toluenesulfonic acid edoxaban, the polymeric carrier and the surfactant in a solvent; spraying and drying to obtain a solid dispersion of the toluenesulfonic acid edoxaban; 2) mixing the solid dispersion of the toluenesulfonic acid edoxaban with other accessories and conducting tabletting. The tablet can significantly improve the dissolution rate and the solubility of a drug, increase the drug absorption and improve the bioavailability. In particular, the tablet significantly improvesthe dissolution behavior in a buffer solution of neutral pH 6.8 compared with the existing preparations.
