Abstract: The present disclosure relates to a novel method for preparing apixaban. The method of the present disclosure is economical since no expensive reagents or solvents are used. In addition, the method is applicable to mass production on an industrial scale because it requires no special conditions or complicated processes and no hazardous reagents or solvents are used. Furthermore, because no toxic solvent is used in the final step of apixaban synthesis and in a purification process, high-purity apixaban can be prepared stably at high yield without the concern of residual solvents.

Abstract: Disclosed are a sustained release solid formulation comprising a drug, for example, oxycodone or its pharmaceutically acceptable salt, in a water-insoluble matrix, which comprises a wax type excipient and copovidone, and thus, has increased compressibility and fluidity and reduced adhesiveness, and a method of preparing the same.
