  • Patent number: 10370376
    Abstract: The present invention relates to an amorphous form of Idelalisib and its methods of preparation. Using a Cu-K? radiation, the X-ray powder diffraction (XRPD) pattern does not contain sharp diffraction peaks at a diffraction angle expressed in degrees 2?, and the X-ray powder diffraction pattern is shown in FIG. 1. The present invention also provides a preparation method for the amorphous form of Idelalisib. The amorphous form of Idelalisib of the present invention increases the solubility of Idelalisib and improves bioavailability of the drug product. As compared to the existing crystalline forms of Idelalisib, its solubility increases significantly, which improves body's absorption of the drug and makes it more efficacious in the clinical therapeutic treatment of diseases. Under the stress test conditions, the amorphous material can maintain good physical and chemical stabilities. The preparation method of amorphous Idelalisib according to the present invention is simple to operate and easy to implement.
