| titleOfInvention | Oxiracetam compound and pharmaceutical composition thereof |
| abstract | The invention belongs to the technical field of medicine, and provides an oxiracetam compound and a pharmaceutical composition thereof. The X-ray powder diffraction of the oxiracetam compound by Cu-Kalpha ray measurement has characteristic peaks when 2theta is 12.2 degrees, 14.4 degrees, 18.1 degrees, 19.6 degrees, 20.0 degrees, 21.8 degrees, 22.7 degrees, 24.6 degrees or 25.1 degrees. The oxiracetam compound has high crystal purity, and the related substance content is lower than 0.05%. The oxiracetam has favorable stability, and the moisture absorption weight gain does not exceed 0.5% even under high-humidity conditions. The tablet prepared by the pharmaceutical composition containing the oxiracetam has favorable stability, and the total impurity content is lower than 0.2% after the tablet is stored for 24 months. The injection prepared by the pharmaceutical composition containing the oxiracetam has favorable stability, and the total impurity content is lower than 0.2% after the injection is stored for 24 months. |
